Scapular morphology is an extrinsic factor playing role in rotator cuff tear (RCT) etiology. The objective of this study was to evaluate the relationship between critical shoulder angle (CSA) and acromion index (AI) with partial-bursal side and full thickness RCT and the size of the RCT.The hypothesis was that CSA and AI would be greater in partial bursal-side RCT and full-thickness RCT patients and would increase with the size of the RCT.This retrospective study assessed 218 patients who had standard shoulder radiographs and magnetic resonance imaging. Patients were divided into three groups: intact rotator cuff (68), partial bursal-side RCT (34) and full-thickness RCT (116). In the second part, full-thickness RCT patients were divided into four groups according to RCT size; small (1cm), medium (1-3cm), large (3-5cm) and massive (5cm). AI and CSA measurements were evaluated from radiographs.The mean CSA was 32.8̊ in control group, 34.3̊ in partial group and 36.9̊ in full-thickness group. The mean AI was 0.66, 0.68 and 0.72 respectively. Significant difference was found in AI and CSA between full thickness RCT and intact RC group (p0.01), and partial RCT and full thickness RCT group (p0.05) in paired comparisons. In full thickness RCT size groups the mean CSA was 34.2̊, 36.4̊, 39.0̊ and 40.8̊ and mean AI was 0.70, 0.71, 0.73 and 0.79 respectively. Significant difference was found between small-large, small-massive, medium-massive groups for CSA in paired comparisons and between small-massive, medium-massive groups for AI.CSA and AI were significantly greater in full-thickness RCT patients and the size of the RCT increased with CSA and AI. The greater CSA and AI could be predictors for larger RCT.III; Cross-Sectional Design; Prognosis Study.

Objective The aim of this study was to determine the effect of intravenous (IV) tranexamic acid (TRX) use on visual clarity during arthroscopic rotator cuff repair. Methods This prospective, randomized, double-blinded, placebo-controlled study was conducted in patients scheduled for an arthroscopic rotator cuff repair. In total, 60 patients were randomly distributed into two groups: control (28 patients: 11 male, 17 female; mean age=53 years, age range=19-65) and TRX (32 patients: 15 male, 17 female; mean age=50, age range=18-69). In the TRX group, the arthroscopy was performed through the bolus IV administration of 10 mg/kg TRX in 100 ml isotonic saline solution. In the control group, the arthroscopy was performed through the bolus IV administration of 100 ml isotonic saline solution. In both the groups, the IV administration was carried out after the induction of anesthesia. At the end of each procedure, the surgeon rated the visual clarity on a scale from 1 to 10. In addition, operation time (minutes), irrigation amount used in operation (lt), and the need of pressure increase because of bleeding were recorded. Results No adverse effects were seen during the study period. Visual clarity in TRX group was significantly better than the control group (the mean visual clarity scores=8.1/10 (range=7-10) vs 7/10 (range=5-9); p=0.018). The amount of solution was significantly less in the TRX group (10.2 lt (range=3.5-21)) than in the control group (15.8 lt (range=5.8-27); p=0.007, post-hoc power=95.7%), although the operation time was slightly longer in the TRX group (106 minutes (range=50-210)) than in the control group (99 minutes (range=45-165); p=0.24). Moreover, the need for the increase in pressure owing to bleeding was found significantly less in the TRX group (5.8 times (range=(0-9)) than in the control group (9.6 times (range=0-13); p=0.04, post-hoc power=94.5%). Conclusion Preoperative IV TRX administration seems to be effective in improving visual clarity and reducing the need for high pressure and the amount of irrigation fluid during the arthroscopic rotator cuff repair.

Context: ideal rehabilitation method following arthroscopic capsulolabral repair surgery for anterior shoulder instability has not been proven yet. Although rapid or slow protocols were compared previously, home- or hospital-based protocols were not questioned before. Objective: the aim of this prospective unrandomized controlled clinical trial is to compare the clinical outcomes of home-based and hospital-based rehabilitation programs following arthroscopic Bankart repair. Design: non-randomized controlled trial. Setting: orthopedics and physical therapy units of a single institution. Patients: fifty-four patients (49 males and 5 females) with an average age of 30.5 (9.1) years, who underwent arthroscopic capsulolabral repair and met the inclusion criteria, with at least 1-year follow-up were allocated into 2 groups: home-based (n = 33) and hospital-based (n = 21) groups. Interventions: both groups received identical rehabilitation programs. Patients in the home-based group were called for follow-up every 3 weeks. Patients in the hospital-based group admitted for therapy every other day for a total of 6 to 8 weeks. Both groups were followed identically after the eighth week and the rehabilitation program continued for 6 months. Main Outcome Measures: Clinical outcomes were assessed using Disabilities of Arm Shoulder Hand, Constant, and Rowe scores. Mann-Whitney U test was used to compare the results in both groups. Wilcoxon test was used for determining the progress in each group. Results: groups were age and gender matched (P =.61, P =.69). Average number of treatment sessions was 13.8 (7.3) for patients in the hospital-based group. Preoperative Disabilities of Arm Shoulder Hand (27.46 [11.81] vs 32.53 [16.42], P =.22), Constant (58.23 [14.23] vs 54.17 [10.46], P =.13), and Rowe (51.72 [15.36] vs 43.81 [19.16], P =.12) scores were similar between groups. Postoperative scores at sixth month were significantly improved in each group (P =.001, P =.001, and P =.001). No significant difference was observed between 2 groups regarding clinical scores in any time point. Conclusions: we have, therefore, concluded that a controlled home-based exercise program is as effective as hospital-based rehabilitation following arthroscopic capsulolabral repair for anterior shoulder instability., NA

Objective: This study aimed to present middle-term functional and radiological outcomes of the transfer of the lesser tuberosity in the management of reverse Hill-Sachs lesions following posterior dislocations of the shoulder. Patients and methods: With a diagnosis of neglected posterior shoulder dislocation (8 locked, 5 recurrent), 13 male patients (age range: 28-72; mean age: 39.3 years) who underwent the transfer of the lesser tuberosity due to reverse Hill-Sachs lesions, were retrospectively reviewed based on functional and radiological data. The etiologies were: epilepsy in 9 patients, a traffic accident in 2 patients, and fall in 2 patients. To assess the patients' functional level, American Shoulder and Elbow Surgeons (ASES) and Constant Scores were used, and the patients' range of motion at the last follow-up was measured. To evaluate the development of arthrosis, the final follow-up control plain radiographs were examined. The average size of the defects calculated from the axial computed tomography sets was 27% (range: 20%-40%). Results: The average length of follow-up was 30 months (range: 12-67 months). At the last follow-up visit, the main ASES and Constant Scores were 78 and 85, respectively, and the average degrees of flexion, abduction, and external rotation were 163,151, and 70 respectively. The concentric reduction was observed postoperatively. Conclusion: McLaughlin procedure appears to be a safe and effective method in the treatment of neglected posterior shoulder dislocations with reverse Hill-Sachs lesion.

Objectives: In intraarticular distal humerus fractures, internal fixation with double plates is the gold standard treatment. However the optimal plate configuration is not clear in the literature. The aim of this study was to compare the biomechanical stability of the parallel and the orthogonal anatomical locking plating systems in intraarticular distal humerus fractures in artificial humerus models. Methods: Intraarticular distal humerus fracture (AO13-C2) with 5 mm metaphyseal defect was created in sixteen artificial humeral models. Models were fixed with either orthogonal or parallel plating systems with locking screws (Acumed elbow plating systems). Both systems were tested for their stiffness with loads in axial compression, varus, valgus, anterior and posterior bending. Then plastic deformation after cyclic loading in posterior bending and load to failure in posterior bending were tested. The failure mechanisms of all the samples were observed. Results: Stiffness values in every direction were not significantly different among the orthogonal and the parallel plating groups. There was no statistical difference between the two groups in plastic deformation values (0.31 mm-0.29 mm) and load to failure tests in posterior bending (372.4 N-379.7 N). In the orthogonal plating system most of the failures occurred due to the proximal shaft fracture, whereas in the parallel plating system failure occurred due to the shift of the most distal screw in proximal fragment. Conclusion: Our study showed that both plating systems had similar biomechanical stabilities when anatomic plates with distal locking screws were used in intraarticular distal humerus fractures in artificial humerus models.

Introduction The purpose of this study is to investigate the incidence of os acromiale in patients who had reverse shoulder arthroplasty (RSA) for rotator cuff tear arthropathy and the effect of presence of os acromiale on the functional results. Hypothesis We hypothesize than in the presence of os acromiale, the contraction strength of the deltoid would decrease due to the dynamic downward depression of the bony fragment leading to less favorable clinical results. Material and method A total 46 patients with a mean age of 70.8 who had RSA and a minimum follow-up of 24 months were included in this study. Preoperative radiographs, computerized tomography scans and magnetic resonance images were examined to determine the presence of os acromiale. Results A total of 10 patients out of 46 (22%) with os acromiale, all of which were of mesoacromion type, were followed up for 59.7 months. While both groups had significant improvements in Constant, Q-DASH and VAS scores compared to their preoperative status, a significant difference between the groups could not be found. The radiological evaluation showed that the average acromiohumeral distance significantly increased postoperatively in both groups. The acromiohumeral distance was significantly shorter in patients with os acromiale. Discussion While the presence of os acromiale does not have an adverse effect on the clinical results of the RSA, the loose fragment can migrate distally in the postoperative period due to the tension in the deltoid. Level of evidence III, case-control study.

Background: Latissimus dorsi (LD) and teres major (TM) tendon transfers are effective surgical procedures to improve shoulder abduction and external rotation for children with obstetrical brachial plexus palsy (OBPP). Open pectoralis major (PM) tendon Z-plasty and arthroscopic subscapularis (SS) release are 2 options for the release of internal rotation contractures to enhance muscle transfers. This study compared the functional results of LD and TM tendon transfers with open PM tendon Z-plasty or arthroscopic SS release. Methods: the study included 24 patients who underwent LD and TM tendon transfers for OBPP (9 arthroscopic SS release, 15 open PM tendon Z-plasty) with a mean follow-up of 41.33 months (range, 36-60 months) and 47.2 months (range, 36-60 months), respectively. Functional evaluation was made according to range of motion and Mallet scoring system. Results: shoulder abduction–external rotation degrees and scores in all sections of the Mallet scoring system significantly increased in both groups (P, NA

Infection after open fractures is a common complication. Treatment options for infections developed after intramedullary nailing surgery remain a topic of controversy. We therefore used a rat fracture model to evaluate the effects of infection on osseous union when the implant was maintained.In a rat model, (1) does infection alter callus strength; (2) does infection alter the radiographic appearance of callus; and (3) does infection alter the histological properties of callus?An open femoral fracture was created and fixed with an intramedullary Kirschner wire in 72 adult male Sprague-Dawley rats, which were divided into two study groups. In the infection group, the fracture site was contaminated with Staphylococcus aureus (36 animals), whereas in the control group, there was no bacterial contamination (36 animals). No antibiotics were used either for prophylaxis or for treatment. We performed biomechanical (maximum torque causing failure and stiffness), radiographic (Lane and Sandhu scoring for callus formation), and histologic (scoring for callus maturity) assessments at 3 and 6 weeks. The number of bacteria colonies on the femur, wire, and soft tissue inside knee were compared to validate that we successfully created an infection model. The number of bacteria colonies in the soft tissue inside the knee was higher in the infection group after 6 weeks than after the third week, demonstrating the presence of locally aggressive infection.Infection decreased callus strength at 6 weeks. Torque to failure (299.07 ± 65.53 Nmm versus 107.20 ± 88.81, mean difference with 95% confidence interval, 192 [43-340]; p = 0.007) and stiffness at 6 weeks (11.28 ± 2.67 Nmm versus 2.03 ± 1.68, mean difference with 95% confidence interval, 9 [3-16]; p = 0.004) both were greater in the control group than in the group with infection. Radiographic analysis at 6 weeks demonstrated the fracture line was less distinct (Lane and Sandhu score of 2-3) in the infection group and complete union was observed (Lane and Sandhu score of 3-4) in the control group (p = 0.001). Semiquantitative histology scores were not different between the noninfected controls and the rats with infection (score 10 versus 9).Retaining an implant in the presence of an underlying infection without antibiotic treatment leads to weaker callus and impedes callus maturation compared with noninfected controls in a rat model. Future studies might evaluate whether antibiotic treatment would modify this result.This model sets the stage for further investigations that might study the influence of different interventions on fracture healing in implant-associated osteomyelitis. Future observational studies might also evaluate the histological properties of callus in patients with osteomyelitis.

OBJECTIVES In arthroscopic rotator cuff surgery for postoperative analgesia opioids, nonsteroid analgesics, and local anesthetics can be used. This study aimed to compare the effectiveness, additional analgesic requirements, patients satisfaction, and complications of single-shot interscalene and supraclavicular blocks. METHODS After obtaining the ethics committee's approval and informed consent, 50 ASA I-II patients were randomized to either the interscalene (GISB) or supraclavicular (GSCB) group. Preoperatively, patients received an ultrasonography-guided block using 30 ml of 0.5% bupivacaine. In the postoperative period, morphine patient-controlled analgesia was administered as a 0.3-mg/h basal dose and 1-mg bolus dose, with a 20-min lockout time. Postoperative visual analog scale (VAS; 0-10 cm) scores of the patients were evaluated at 4, 8, 12, and 24 h postoperatively; additional analgesic requirements, adverse effects, and complications were recorded. Patient satisfaction (PS) scores were evaluated after 24 h. RESULTS VAS scores at 4 h were lower in the GSCB group than in the GISB group, and the VAS scores at 8, 12, and 24 h were lower in the GISB group than in the GSCB group, with no statistical significance. Additional analgesic requirements was 28% in the GISB group and 68% in the GSCB group (p < 0.05). Total morphine consumption was lower in the GISB group than in the GSCB group (18.95±9.2 mg vs. 30.6 ± 9.6 mg; p < 0.001). PS scores were higher in the GISB group than in the GSCB group (7.0±1.0 vs. 6.1±0.9; p < 0.01). Adverse effects and complication rates were similar in both the groups. In GISB group, seven patients (28%) had nausea/vomiting, whereas in the GSCB group, 12 patients (48%) had nausea/vomiting. This difference was statistically insignificant. CONCLUSION Supraclavicular block can be considered as an alternative to interscalene block for arthroscopic shoulder surgery.

Objective: The aim of this study was to evaluate the long-term radiological and functional results of distraction interposition arthroplasty using an Achilles tendon allograft.Methods: The study included 5 patients (3 females and 2 males; mean age: 31 years, range: 25 to 41 years) who underwent distraction interposition arthroplasty for stiff elbow and arthrosis due to intrinsic factors between 2001 and 2010. Interposition with fresh-frozen Achilles allograft and collateral ligament reconstruction were performed in all patients. Mean follow-up period was 87.6 (range: 40 to 131) months. Mean distraction time with an external fixator was 7 (range: 6 to 8) weeks. Elbow motion was allowed in the first postoperative day in all patients. Radiological evaluation was performed pre- and postoperatively. Elbow ROM, and the Mayo Elbow Performance Score (MEPS) and DASH scores were recorded for functional evaluation.Results: Mean preoperative flexion-extension range was 24° (range: 0° to 80°) and mean supination-pronation range was 15°. Two patients had elbow ankylosis in 90° and 60° of flexion at the preoperative examination. Mean postoperative flexion-extension range increased significantly to 81° (range: 50° to 110°) (p, Amaç: Bu çalışmada Aşil tendon allogrefti kullanılarak yapılan distraksiyon interpozisyon artroplastisinin uzun dönem radyolojik ve fonksiyonel sonuçlarının değerlendirilmesi amaçlandı.Çalışma planı: 2001-2010 yılları arasında intrensek kaynaklı dirsek sertliği ve artrozu nedeniyle distraksiyon interpozisyon artroplastisi uygulanan 5 hasta (3 kadın, 2 erkek; ortalama yaş: 31, dağılım: 25-41) çalışmaya alındı. Tüm hastalarda taze donmuş Aşil allogrefti ile interpozisyon ve kollateral bağ rekonstrüksiyonu uygulandı. Hastaların ortalama takip süresi 87.6 (dağılım: 40-131) ay idi.

Objective: The aim of this study was to clinically and radiologically evaluate patients treated with plate osteosynthesis with structural allografts for severely valgus-impacted fractures of the proximal humerus.Methods: The study included 10 patients (average age: 57 years; range: 34 to 77 years) with valgus-impacted Neer Type 4 proximal humerus fractures. Fractures were classified according to the Robinson classification. Patients were called for an up-to-date examination and evaluated radiologically and clinically with Constant and DASH scores.Results: Average follow-up period was 22.5±12.2 (range: 12 to 50) months. Average DASH score at the final follow-up was 7.6±4.5 (range: 2.5 to 16.7) and average Constant score was 87.7±4.4 (range: 83 to 94). None of the cases had early or late head collapse. There was no avascular necrosis. One early screw penetration was observed.Conclusion: Surgical treatment of valgus-impacted proximal humerus fractures achieved successful results. However, the cavity under the humeral head may lead to failure due to mechanical insufficiency. Plate osteosynthesis with structural allografts warrants initial mechanical support until union, thus avoiding complications related to head collapse., Amaç: Bu çalışmada yapısal allogreftlerle yapılan plak osteosentezi ile ileri derecede valgus impakte kırıkları üzerinde alınacak sonuçların klinik ve radyolojik açıdan değerlendirilmesi amaçlanmıştır.Çalışma planı: Valgus impakte Neer Tip 4 proksimal humerus kırığı tanısı alan ve ortalama yaşı 57 (dağılım: 34-77) olan 10 hasta çalışmaya dahil edilerek, kırıkları Robinson sınıflamasına göre sınıflandı. Hastalar güncel muayeneleri için çağrıldı; Constant ve DASH skorları ile klinik ve radyolojik olarak değerlendirildiler.Bulgular: Ortalama takip süresi 22.5±12.2 (dağılım: 12-50) ay olarak kaydedildi. Son kontrol sırasında ortalama DASH skoru 7.6±4.5 (dağılım: 2.5-16.7) ve Constant skoru 87.7±4.4 (dağılım: 83-94) olarak ölçüldü. Hastaların hiçbirinde erken ve geç baş çökmesi veya avasküler nekroz görülmedi. Bir hastada erken vida penetrasyonu saptandı.Çıkarımlar: Valgus impakte kırıkların cerrahi tedavisi ile başarılı sonuçlar elde edilmiştir. Bununla birlikte, humerus başının altında ortaya çıkan kavite, mekanik yetersizlik nedeniyle başarısızlığa yol açabilir. Yapısal allogreftler ile yapılan plak osteosentezi, başlangıç aşamasından kaynamaya dek yeterli mekanik desteği sağlayarak, baş çökmesi ile ilişkili komplikasyonlar oluşmasına engel olmaktadır.

Powerful contractions during epileptic seizures may cause shoulder dislocation and instability. The aim of the study is to evaluate the functional and radiographic results of the Latarjet procedure for anterior shoulder dislocation in patients with epilepsy and compare the functional results of these patients with the results of patients without epilepsy.Is latarjet procedure effective in epileptic patients as non-epileptic patients with anterior shoulder instability?Eleven shoulders of 9 patients with epileptic seizures causing anterior shoulder instability were evaluated retrospectively. All patients had a Latarjet procedure after neurologic evaluation and treatment arrangement. Epileptic seizures after the operation and shoulder dislocation after a seizure were investigated. For functional evaluation, ROWE, ASES and Constant scores were utilized whereas standard X-ray views were used for radiologic evaluation. The results of epileptic patients with Latarjet procedure were compared with non-epileptic patients (53 patients, 54 shoulders) for anterior shoulder instability.Three (33%) of the 9 epileptic patients had recurrent seizures after Latarjet procedure, whereas 1 of the 11 shoulders (9%) had dislocation after an epileptic seizure. Functional scores were found to be significantly improved in epileptic (P0.001) and non-epileptic patients (P0.001). No significant differences for functional results were found between epileptic and non-epileptic patients after Latarjet procedure for anterior instability (P0.05). One shoulder of 11 in the patients with epilepsy group (9%) and one shoulder of the 54 shoulders non-epileptic patients group (1.8%) had a redislocation. The rate of postoperative redislocation was significantly higher in patients with epilepsy (P=0.008).Epileptic patients have a high rate of recurrent seizures even with proper medical treatment. Significant functional improvements and shoulder stability may be achieved after Latarjet procedure in epileptic patients. These functional results were comparable with those of non-epileptic patients with Latarjet procedure for anterior shoulder instability.III (case-control study).

To investigate anatomic relation of standard and coaxial ankle arthroscopy portals with neurovascular structures during different degrees of ankle motion. Twenty posterior ankles of ten fresh cadavers were assessed. Posteromedial, posterolateral and coaxial (transmalleolar) portals were created using 4-mm Steinmann pins in accordance with the defined technique in neutral position. The ankles were then dissected, and the distance from the portals to the peroneal tendons, short saphenous vein and sural nerve was measured laterally and that from the tibial nerve, flexor hallucis longus tendon and posterior tibial artery was measured medially. Changes in the distance between these structures were noted in neutral positions, 15° of dorsiflexion and 30° plantar flexion. In the neutral position, the mean distance of the conventional posterolateral portal to the sural nerve was 6 mm (SD 2.9, range 2.7–14.5). The mean distance of the posterolateral coaxial portal to the peroneal tendon was 1.6 mm (SD 0.55, range 1.1–2.9). The mean distance of the posteromedial portal to the FHL was 2.11 mm (SD 1.1, range 0–4.7). The mean distance of the posteromedial coaxial portal to the posterior tibial artery was 6 mm (SD 1.4, range 3.9–9.5). Although not statistically significant, the distance between the portal and neurovascular structures increased in dorsiflexion for the portals placed posteriorly to the neurovascular structures and increased in plantar flexion for the portals placed anterior to the neurovascular structures. In comparison with the portals made in the neutral position, the distance between neurovascular structures and portals changes with portal placement in plantar flexion and dorsiflexion. In clinical practice, therefore, it might be safer to place the posteromedial–posterolateral portals in dorsiflexion and posterolateral–posteromedial coaxial portals in plantar flexion. The tibial nerve is closer to the posteromedial coaxial in dorsiflexion and could be in danger if making this portal with the foot in this position.

Background Patients with obstetrical brachial plexus palsy (OBPP) sequela exhibit adduction and internal rotation contractures. The muscular imbalance may result in secondary bony changes. Tendon transfers and muscular releases may improve shoulder function in these patients. The aim of this study is to evaluate the functional and radiological results of pectoralis major tendon Z-plasty with transfer of latissimus dorsi and teres major tendons to rotator cuff tendons without release of subscapularis muscle in patients with mild sequela of OBPP. Materials and methods Twenty-six consecutive patients, who were treated with tendon transfer and met the eligibility criteria, were included in the study. No additional humeral osteotomy or subscapularis tenotomy was performed. Functional evaluation is made according to range of motion and Mallet scoring system. Preoperative radiologic evaluation was made according to the grading system of Waters. Results A significant increase in shoulder function was found in all patients. Postoperative radiographs revealed glenohumeral congruity was maintained in all patients. Improvement in shoulder abduction and external rotation was higher in patients who were operated before the age of 7. Discussion/conclusion Pectoralis major tendon lengthening with transfer of latissimus dorsi and teres major tendons to rotator cuff is an effective and reproducible technique and can improve shoulder functions in patients with OBPP. Subscapularis release is not always required to overcome internal rotation contracture. Secondary glenohumeral changes might also be prevented with this approach.

OBJECTIVES Arthroscopic rotator cuff surgery can result in severe postoperative pain. We compared a continuous subacromial infusion to a continuous interscalene block with levobupivacaine for patients undergoing arthroscopic rotator cuff surgery. METHODS Sixty patients were randomized to two groups: 1) interscalene block with 0.5% levobupivacaine (30 mL) followed by a postoperative subacromial infusion: 0.125% levobupivacaine 5 mL/h basal infusion, 5 mL bolus dose and a 20 min lockout time or; 2) interscalene block with 0.5% levobupivacaine (30 mL) followed by a postoperative interscalene infusion: 0.125% levobupivacaine 5 mL/h basal infusion, 5 mL bolus dose and a 20 min lockout time. Infusions were maintained for 48 hours. RESULTS The VAS scores in the postanesthesia care unit and at 4 h were not different. The VAS scores at 8, 12, 24, 36 and 48 h were lower than 4 in both groups; but they were significantly lower in the interscalene group. Additional analgesic requirements were lower in the interscalene group (16.6% vs 53.3%, p

Introduction: Hemophilia is a hereditary bleeding disorder that presents with primarily hemarthrosis and hematoma. The most common and frequent complication, especially in severe hemophilia, where factor VIII or IX is not administered prophylactically, is the hemophilic arthropathy that develops as a result of recurrent bleeding. In this study, the relationship between arthropathy development and timing of the prohylaxis and orthopedic interventions in hemophiliacs was presented. Materials and Methods: The data of 99 haemophilia (HA) and hemophilia B (HB) patients under the age of 25 years at our center were reviewed retrospectively. Age, type of disease, factor level, follow-up duration, prophylaxis dose and frequency, annual bleeding rate (ABR), target joints, arthropathic joints, applied radioactive synovectomy and orthopedic interventions were recorded. Results: Seventy-six HA and 23 HB were included. The median age was 14 (range 1-25) years old. Ten of them (10.1%) were mild, 15 (15.2%) were moderate and 74 (74.7%) were severe. Severe hemophiliacs were most of the patients in both types. Eighty-nine (89.9%) patients including 17 of mild-to-moderate type with target joint and / or surgical intervention were under prophylaxis and 10 (10.1%) were receiving on-demand therapy. The annual bleeding rate was 1.38. Twelve (12%) patients (8 HA, 4 HB) with degenerative hemophilic arthropathy had a mean age of 22 years old and a mean age of application was 12.3 years, a mean annual bleeding rate was 1.54 and a mean follow up and prophylaxis time was 9.5 years. Six patients (4 HA, 2 HB) with median age 21.8 years (range: 18-25) had 9 major orthopedic surgeries (arthrodesis (2), radial head resection (2), TEP, contracture releasing, acyloplasty, deformity correction, arthroscopic sinovectomy) and 22 patients with median age of 17.8 years had 29 minor orthopedic interventions (radiosynovectomy (28), closed reduction to femur fracture). Orthopedic interventions were performed at an advanced age, often who met with prophylaxis too late. Discussion: In our study, it has been shown that who had prophylaxis at an early age and prophylaxis for a longer period had less arthropathies which is the most important complication and additionally less arthroplasties. The fact that, the prevalence of permanent musclosceletal deformity was 59% before year 2000 (historical data) which reduced to 12% nowadays shows the sensitivity of hemophilia care in our center. Early and regular prophylaxis remains the most current treatment modality for the prevention of hemophilia complications. Disclosures No relevant conflicts of interest to declare.

Here, we report a series of 5 patients (6 shoulders) diagnosed with neuropathic arthropathy of the shoulder joint in our clinic between 2005 and 2008. Initial diagnosis, previous treatment, and radiological and clinical follow-up findings were reviewed. The mean age at diagnosis was 44.2 years. Four patients had unilateral and 1 patient had bilateral involvement. The presenting symptoms were pain, swelling, and loss in range of motion. Active forward flexion and abduction ranged from 0° to 90°. Hypoesthesia and loss of temperature sense was evident in 3 patients. Radiographs showed massive osteolysis of humeral head and glenoid process, and magnetic resonance imaging showed periarticular fluid collection, and degeneration at the rotator cuff and shoulder joint, resembling chronic septic arthritis or sarcoma. Biopsy was performed in 4 patients before definitive diagnosis, and synovial hypertrophy and necrotic bone was found. Two patients had a history of operated cervical syringomyelia, and the remaining 3 patients were later diagnosed to have syringomyelia and referred to neurosurgery clinic, where 2 of those were operated. Four patients were followed-up with symptomatic therapy, and 1 patient underwent an unsuccessful shoulder arthroplasty in another clinic. As a conclusion, neuropathic arthropathy of the shoulder is rare, and correct diagnosis is possible by careful physical and neurological examination and pathologic evaluation when needed.

Objectives: The role of intermittent ultrasound in the conservative treatment of subacromial impingement syndrome (SIS) has not been clarified. We aimed to evaluate the efficacy of ultrasound treatment in SIS.Methods: Thirty-six patients (29 females, 7 males; mean age 51 years; range 40 to 69 years) with type II SIS were randomized to two groups to receive intermittent ultrasound (group 1, n=20) and placebo ultrasound (group 2, n=16) for three weeks (15 sessions). All the patients received the same standard physical therapy and rehabilitation modalities besides ultrasound treatment. Evaluations were made before and three and six weeks after treatment. Functional results were assessed by the Constant score, pain was assessed by a visual analog scale, and range of motion was measured.Results: Within-group comparisons showed significant improvements in both groups three and six weeks after treatment (p0.05). The Constant score improved from 43.7±12.9 to 65.7±7.7 in group 1, and from 43.9±16.4 to 65.3±7.6 in group 2. Pain scores decreased from 5.5 to 2 and from 5 to 1 in group 1 and 2, respectively. Improvements in Constant scores and pain scores were similar in both groups (p>0.05).Conclusion: Our findings suggest that intermittent ultrasound added to conservative treatment of SIS do not provide an additional benefit to the patients., Amaç: Kesikli ultrasonun subakromiyal sıkışma sendromunun (SSS) tedavisindeki yeri şimdiye kadar yeterince incelenmemiştir. Bu çalışmada ultrasonun SSS’nin konservatif tedavisindeki etkisi araştırıldı.Çalışma planı: Tip II SSS tanısı konan 36 hasta (29 kadın, 7 erkek; ort. yaş 51, dağılım 40-69) randomize olarak iki gruba ayrıldı. Yirmi hastaya (grup 1) kesikli ultrason, 16 hastaya (grup 2) plasebo ultrason uygulandı. İki grupta da tedavi 15 seans (3 hafta) sürdürüldü. Tüm hastalara ultrason dışında aynı standart fizik tedavi ve rehabilitasyon programı uygulandı. Değerlendirmeler, tedaviden önce ve tedaviden üç ve altı hafta sonra yapıldı. Fonksiyonel sonuç Constant skoru, ağrı görsel analog skala ile değerlendirildi; hastaların hareket açıklıkları ölçüldü. Sonuçlar: İki grupta da tedavinin üçüncü ve altıncı haftalarındaki düzelmeler anlamlı bulundu (p0.05). Grup 1 ve 2’de tedavi öncesinde sırasıyla 43.7±12.9 ve 43.9±16.4 olan ortalama Constant skoru altıncı hafta sonunda 65.7±7.7 ve 65.3±7.6’ya yükseldi. Grup 1’de tedaviden önce 5.5 olan ağrı skoru son kontrolde 2’ye, grup 2’de ise 5’ten 1’e düştü. Constant skoru ve ağrı skorundaki düzelmeler iki grup arasında anlamlı farklılık göstermedi (p>0.05).Çıkarımlar: Bulgularımız, SSS tanısı konan hastaların konservatif tedavisinde kesikli ultrason uygulamasının ek yarar sağlamadığını göstermektedir.

Objectives: The purpose of this study was to determine the calcaneal angles on radiograms of individuals without a calcaneal fracture.Methods: We retrospectively analyzed a total of 308 digital records of lateral ankle or foot radiographs taken from 268 patients (106 males, 162 females; mean age 42 years; range 18-79 years) without a calcaneal fracture. On these radiographs, the reference lines were drawn with the use of an angle measurement software with a sensitivity of 1/100 mm and the Böhler (BA) and Gissane (GA) angles were measured. The distribution characteristics of the angles with respect to age, gender, and side of the body were analyzed and compared with those of previous studies.Results: The mean BA was 33.8±4.8° (range 20° to 46°) and the mean GA was 115.0±6.5° (range 100° to 133°). There were no significant differences for both angles with respect to measurements obtained from the right and left sides (for BA, p=0.198; for GA, p=0.601) and from both sexes (for BA, p=0.177; for GA, p=0.412). The highest (35.2°) and lowest (32.3°) means of BA were seen in the age brackets of 41-50 and 61-83 years, respectively. The corresponding age brackets for GA were 21-30 and 51-60 years with 115.7° and 114.4°, respectively. There were no significant differencesbetween the age groups for both angles (for BA, p=0.086; for GA, p=0.955). Of note, the mean BA was significantly higher than those reported in previous studies. There was no correlation between BA and GA (r=0.018; p=0.76), nor between the calcaneal angles and age (for BA, r=-0.092; p=0.11 and for GA, r=-0.070; p=0.22).Conclusion: The calcaneal angles show considerable variations in diverse ethnic groups and populations in terms of normal range, age, gender, and side. The ranges herein reported (20-46° for BA, 100-133° for GA) can be used as reference values for the Turkish population., Amaç: Kalkaneus kırığı bulunmayan kişilerin radyografilerinde ölçülen kalkaneus açılarının dağılımı ve normal sınırlarının belirlenmesi amaçlandı.Çalışma planı: Çalışmada, kalkaneus kırığı bulunmayan 268 hastaya ait (106 erkek, 162 kadın; ort. yaş 42; dağılım 18-79) 308 adet dijital yan ayak ve ayak bileği grafisi geriye dönük olarak incelendi. Bu grafiler üzerinde, 1/100 mm duyarlıkta açı ölçümü yapan bir yazılım yardımıyla referans çizgileri çizilerek, Böhler (BA) ve Gissane (GA) açıları ölçüldü. Açıların dağılım özellikleri, cinsiyet, yaş ve taraf ile olan ilişkileri incelendi. Saptanan dağılım özellikleri literatürdeki diğer çalışmaların sonuçlarıyla karşılaştırıldı. Sonuçlar: Böhler açısı ortalama 33.8±4.8° (dağılım 20°-46°), GA ise ortalama 115.0±6.5° (dağılım 100°-133°) bulundu. Her iki açı için sağ ve sol taraf ortalamaları arasında (BA için p=0.198; GA için p=0.601) ve cinsiyetler arasında (BA için p=0.177; GA için p=0.412) anlamlı fark bulunmadı. En yüksek (35.2°) ve en düşük (32.3°) ortalama BA değerleri sırasıyla 41-50 ve 61-83 yaş gruplarında görüldü. Gissane açısı için en yüksek (115.7°) ve en düşük (114.4°) ortalama değerler sırasıyla 21-30 ve 51-60 yaş grubunda idi. Yaş grupları arasında anlamlı farklılık saptanmadı (BA için p=0.086; GA için p=0.955). Ortalama BA değeri literatürdeki diğer sonuçlardan anlamlı derecede farklı bulundu. Korelasyon analizinde BA ve GA arasında anlamlı ilişki saptanmadı (r=0.018; p=0.76). Kalkaneus açılarıyla yaş arasında da anlamlı bir ilişki yoktu (BA için: r=-0.092; p=0.11 ve GA için: r=-0.070; p=0.22).Çıkarımlar: Kalkaneus açıları farklı ırk ve toplumlarda farklı normal sınırlar; yaş, cinsiyet ve tarafa göre farklı dağılım gösterebilir. Örnek grubumuzda saptanan BA için 20°-46°, GA için 100°-133° aralığı Türk toplumu için referans değerleri olarak kullanılabilir.

Objectives: We evaluated functional results of patients treated with open reduction and internal fixation with the parallel-plate technique for complex distal humerus fractures.Methods: Twenty-one patients (14 males, 7 females; mean age 47 years; range 16 to 85) underwent open reduction with olecranon osteotomy and internal fixation with the parallel-plate technique for distal humerus fractures accompanied by highly intra-articular or metaphyseal comminution (n=10), intra-articular comminution and osteoporosis (n=7), and intra-articular and metaphyseal comminution with bone loss (n=4). According to the AO classification, there were 12 C3, six C2, and three C1 type fractures. Eight patients had open fractures. The mean time to surgery was six days (range 1 to 17 days). Functional results were evaluated using the Mayo elbow performance score, Jupiter elbow score, and DASH (Disabilities of the Arm, Shoulder and Hand) score. The mean follow-up was 28 months (range 12 to 48 months).Results: The mean total range of motion was 90.2±31.1°, flexion was 118.1±17.4°, and extension was 27.8±17.4°. The mean Mayo elbow performance score and DASH score were 86.1±12.6 and 7.6±9.5, respectively. According to the Jupiter elbow scores, the results were excellent in seven patients, good in 11 patients, moderate in two patients, and poor in one patient. Radiographically, solid union was achieved in all the patients. Heterotopic ossification of varying degrees was seen in seven patients, two of whom underwent resection of heterotopic ossification due to severe limitation of movement. Debridement was performed in one patient due to the development of deep infection. Chondrolysis of the elbow occurred in one patient. Patients with open fractures had significantly lower range of motion than those with closed fractures (p0.05).Conclusion: Functional results are satisfactory in distal humerus fractures treated with stable osteosynthesis and parallel-plate technique that allow early active motion., Amaç: Kompleks humerus distal uç kırığı nedeniyle açık redüksiyon ve paralel plak tekniğiyle internal tespit uygulanan hastaların fonksiyonel sonuçları değerlendirildi.Çalışma planı: Kompleks distal uç humerus kırığı nedeniyle 21 hasta (14 erkek, 7 kadın; ort. yaş 47; dağılım 16-85) olekranon osteotomisi ile açık redüksiyon ve paralel plak tekniğiyle tedavi edildi. Kırıklara ileri derecede eklemiçi veya metafizer parçalanma (n=10), eklemiçi parçalanma ve osteoporotik özellikler (n=7), eklemiçi ve metafizer parçalanma ile birlikte kemik kaybı (n=4) eşlik etmekteydi. AO sınıflamasına göre, kırıkların 12’si C3, altısı C2, üçü C1 kırık idi. Sekiz hastada açık kırık vardı. Kırık ile ameliyat zamanı arasındaki süre ortalama altı gün (dağılım 1-17 gün) idi. Fonksiyonel sonuçlar Mayo dirsek performans skoru, Jupiter dirsek skoru ve Kol, Omuz ve El Engellilik (DASH) skoru ile değerlendirildi. Ortalama takip süresi 28 ay (dağılım 12-48 ay) idi.Sonuçlar: Toplam hareket açıklığı ortalama 90.2±31.1°, fleksiyon 118.1±17.4°, ekstansiyon 27.8±17.4° bulundu. Mayo dirsek performans skoru ortalama 86.1±12.6, DASH skoru 7.6±9.5 idi. Jupiter dirsek skoruna göre sonuçlar yedi hastada mükemmel, 11 hastada iyi, iki hastada orta, bir hastada kötü olarak değerlendirildi. Radyografik olarak, hiçbir hastada kaynama sorunuyla karşılaşılmadı. Yedi hastada (%33.3) değişik derecelerde heterotopik ossifikasyon görüldü; iki hastaya ciddi hareket kısıtlılığı nedeniyle heterotopik ossifikasyon rezeksiyonu yapıldı. Bir hastada derin enfeksiyon nedeniyle debridman yapıldı. Bir hastada ise dirsek ekleminde kondroliz gelişti. Açık kırıklı hastaların hareket açıklığı anlamlı derecede daha düşük bulunurken (p0.05). Çıkarımlar: Erken harekete izin verecek stabilitede osteosentez tekniği ve paralel plaklama tekniği ile tedavi edilen distal humerus kırıklarında fonksiyonel sonuçlar tatmin edicidir.

Objectives: Despite the developments in chemotherapy protocols, improvement in the survival rates of osteosarcoma has been limited. We evaluated the effect of certain prognosis-related proteins on survival of patients with osteosarcoma.Methods: Data from 45 patients (24 males, 21 females) who were treated and followed-up for osteosarcoma were reviewed. Following neoadjuvant chemotherapy, 41 patients underwent extremity saving surgery, and four patients underwent amputation. The most frequent localization was the lower end of the femur (n=23, 51.1%), followed by the upper end of the tibia (n=10, 22.2%). Three patients had metastasis on admission. Surgical resection samples were retrieved from the pathology archive and analyzed immunohistochemically for the expression of p-glycoprotein p170, p53, heat-shock protein 27 (HSP27), HSP90, and nm23. The effect of these proteins on prognosis and survival was assessed with survival analysis using the Kaplan-Meier method. The mean follow-up was 49.7 months (range 6 to 185 months).Results: Three patients with metastasis on admission died within five years due to pulmonary metastasis. New metastases developed in 29 patients. Total 5-year and 10-year survival rates were 60% and 43%, respectively. The corresponding diseasefree survival rates were 41% and 24%. Five-year survival was 29% in patients who developed metastasis. Among clinical factors, survival was influenced only by the presence of metastasis on admission (p=0.044). Five-year and 10-year survival rates were significantly different between patients with and without p53 positivity (p=0.04), while the other proteins were not significantly associated with survival.Conclusion: Our data suggest that p53 may be used as a prognostic marker in osteosarcoma due to its significant association with survival., Amaç: Kemoterapi rejimlerindeki gelişmelere rağmen osteosarkom sağkalımında çok az ilerleme olmuştur. Bu çalışmada, osteosarkomlu hastalarda prognoz ile ilişkili bazı proteinlerin sağkalım ile ilişkisi değerlendirildi.Çalışma planı: Tedavisi ve izlemi hastanemizde yapılan 45 hastanın (24 erkek, 21 kadın) verileri geriye dönük olarak incelendi. Osteosarkom nedeniyle, neoadjuvan kemoterapi sonrasında, 41 hastaya ekstremite koruyucu cerrahi, dört hastaya amputasyon yapılmıştı. En sık tutulum 23 hasta (%51.1) ile femur alt uç, 10 hasta (%22.2) ile tibia üst uçta görüldü. Üç hastada başvuru anında metastaz vardı. Cerrahi rezeksiyon örnekleri patoloji arşivinden çıkartılarak, p-glikoprotein p170, p53, ısı şok proteini 27 (HSP27), HSP90 ve nm23 proteinlerinin ekspresyonu immünohistokimyasal yöntemlerle incelendi. Bu proteinlerin prognoz ve sağkalım üzerindeki etkileri Kaplan-Meier yöntemi ile değerlendirildi. Hastaların ortalama takip süresi 49.7 ay (dağılım 6-185 ay) idi.Sonuçlar: Başvuru anında metastaz saptanan üç hasta beş yıl içinde akciğer metastazından yaşamını yitirdi. Yirmi dokuz hastada metastaz gelişti. Beş ve 10 yıllık genel sağkalım oranları sırasıyla %60 ve %43 bulundu. Hastalıksız sağkalım oranı ise beş yıl için %41, 10 yıl için %24 idi. Metastaz gelişen hastalarda beş yıllık sağkalım oranı %29 idi. Klinik faktörler içinde, sağkalımı anlamlı etkileyen sadece başvuru anında metastaz varlığı idi (p=0.044). p53 proteininin pozitif ve negatif ekspresyonları arasında beş yıl ve on yıllık sağkalım oranları açısından anlamlı fark görülürken (p=0.04), incelenen diğer proteinler sağkalımla ilişkili bulunmadı.Çıkarımlar: p53 ekspresyonu ile sağkalım arasındaki ilişki, p53’ün osteosarkomda prognostik gösterge olarak kullanılabileceğini düşündürmektedir.

We compared time-dependent changes in the biomechanical properties of single-and double-row repair of a simulated acute tear of the rotator cuff in rabbits to determine the effect of the fixation techniques on the healing process. A tear of the supraspinatus tendon was created in 80 rabbits which were separated into two equal groups. A single-row repair with two suture anchors was conducted in group 1 and a double-row repair with four suture anchors in group 2. A total of ten intact contralateral shoulder joints was used as a control group. Biomechanical testing was performed immediately post-operatively and at four and eight weeks, and histological analysis at four and eight weeks. The mean load to failure in group 2 animals was greater than in group 1, but both groups remained lower than the control group at all intervals. Histological analysis showed similar healing properties at four and eight weeks in both groups, but a significantly larger number of healed tendon-bone interfaces were identified in group 2 than in group 1 at eight weeks (p < 0.012). The ultimate load to failure increased with the number of suture anchors used immediately post-operatively, and at four and eight weeks. The increased load to failure at eight weeks seemed to be related to the increase in the surface area of healed tendon-to-bone in the double-row repair group.

Objectives: The purpose of this study was to evaluate early postoperative biomechanical changes in plicated joint capsules and to determine the effect of debridement to create a bleeding inner capsular surface on the healing process.Methods: Fifty-four mature New Zealand white rabbits were used. Plication was performed in unilateral medial knee joint capsules of 48 rabbits either alone (n=24) or following debridement (n=24) to create a bleeding inner capsular surface. Six rabbits remained untreated for the control group. The operated knee joints were immobilized in flexion postoperatively. The rabbits from the two study groups were sacrificed in groups of six immediately after operation, in the first, second, and third weeks, of which five were evaluated in tensile tests and one was evaluated histologically.Results: Compared to the controls, tensile strengths were significantly higher in both study groups until the third week (p0.05). The strength of the plicated capsules was significantly higher in the first week in both study groups than those measured in subsequent weeks (p0.05). Compared to its absence, the use of debridement was associated with a significantly lower strength in the first week (p0.05). Histological findings were similar in the two study groups and were characterized by healing with increased fibrosis starting from the first week.Conclusion: A plicated capsule would not be weaker than an intact one. Our findings do not favor debridement for a more rapid and better healing process. Rather, it might have adverse effects on the biomechanical properties of the capsule., Amaç: Plikasyon uygulanan eklem kapsülünde ameliyat sonrası erken dönemde meydana gelen biyomekanik değişimler araştırıldı ve debridman ile kapsül iç yüzünde kanamalı bir yüzey oluşturulmasının iyileşme üzerine etkisi değerlendirildi.Çalışma planı: Elli dört yetişkin Yeni Zelanda beyaz tavşanının 48'inin tek taraf diz medial eklem kapsülüne tek başına (n=24) ya da debridmanla kapsül iç yüzünde kanamalı bir yüzey oluşturulduktan sonra (n=24) plikasyon yapıldı. Altı tavşanın sağlam dizi kontrol grubunu oluşturdu. Ameliyat sonrasında tavşanların dizleri tespit edildi. Debridman uygulanan ve uygulanmayan gruplarda altışar tavşanın yaşamı sırasıyla ameliyattan hemen sonra, birinci ikinci ve üçüncü haftalarda sonlandırıldı. Her altgrupta beş tavşan mekanik testler için, bir tavşan ise histolojik değerlendirme için kullanıldı.Sonuçlar: Deney gruplarında kopma kuvveti üçüncü haftaya kadar kontrol grubundan yüksek bulundu (p0.05). Ayrıca, birinci haftadaki kopma kuvveti, ikinci ve üçüncü hafta sonuçlarından anlamlı derecede yüksekti (p0.05). Debridman uygulanmayan gruba göre, debridman uygulanan grubun birinci haftadaki kopma kuvveti belirgin olarak daha azdı (p0.05). Histolojik örneklerde deney gruplarında tüm haftalarda benzer bulgular elde edildi; birinci haftadan itibaren her iki grupta da artan fibrozisle birlikte iyileşme gözlendi.Çıkarımlar: Plikasyondan sonra kapsül, sağlam kapsülden daha zayıf değildir. Debridmanla daha hızlı veya daha iyi iyileşme olduğu gösterilememiştir. Debridman kapsülün biyomekanik özelliklerini olumsuz etkileyebilir.

Objective: The purpose of this study was to evaluate the functional and radiological results of semiconstrained Coonrad-Morrey total elbow arthroplasty for distal humeral nonunions in the mid-term period.Methods: Seven patients were treated with Coonrad-Morrey total elbow arthroplasty for distal humeral nonunion. All patients were female, and the mean age was 65.6 years (range: 64–68 years). Patients were followed for at least 5 years, and the mean follow-up time was 73 months (range: 63–84 months). Anteroposterior and lateral radiographs at preoperative and early postoperative period of the joint replacement and latest follow-up were used to detect postoperative radiological changes in terms of loosening. The Mayo Elbow Performance Index (MEPI) and Q-DASH Score were used for functional evaluation.Results: At the latest follow-up, joint stability had been achieved in all 7 patients. Six patients (85.7%) were pain free. The mean range of motion was 30° (range: 0–60°) preoperatively, and this improved to 90.7° (range: 60–110°) at the latest follow-up (p, Amaç: Bu çalışmada, distal humerus kaynamamalarının tedavisinde Coonrad-Morrey total dirsek protezinin orta dönem fonksiyonel ve radyolojik sonuçlarının değerlendirilmesi amaçlandı.Çalışma planı: Distal humerus kaynamama nedeniyle 7 hastaya Coonrad-Morrey total dirsek artroplastisi uygulanmıştır. Tamamı kadın olan n hastaların ortalama yaşı 65.6 idi. Ortalama takip süresi 73 ay iken minimum takip süresi 5 yıl olarak tespit edilmiştir. Ameliyat öncesi, hemen sonrası ve son kontrolde elde edilen dirsek anteriorposterior ve lateral grafileri ile radyolojik değişiklikler ve gevşeme değerlendirilirken, Mayo Elbow Performance Index (MEPI) ve Q-Dash skorları fonksiyonel değerlendirmede kullanılmıştır.Bulgular: Son kontrolde, 7 hastada da dirsek stabilitesinin sağlandığı görüldü. 6 hastanın(%87.5) ağrısı yoktu. Ameliyat öncesi 30° olan ortalama hareket açıklığının , son kontrolde ortalama 90.7° ye arttığı tespit edildi (p

Background and objectives: The aim of the study were to demonstrate the possible hemodynamic changes and cerebral blood flow alterations in patients who were positioned from supine to beach chair position; and to detect if the position change causes any cortical activity alteration as measured by the 4-channeled electroencephalography monitor. Methods: 35 patients were included. Before the induction, mean arterial pressure and patient state index values were recorded (T0). After the intubation, doppler-ultrasonography of the patients’ internal carotid and vertebral arteries were evaluated to acquire cerebral blood flow values from the formula. In supine position, mean arterial pressure, patient state index and cerebral blood flow values were recorded (T1) and the patient was positioned to beach chair position. After 5 min all measurements were repeated (T2). Measurements of patient state index and mean arterial pressure were repeated after 20 (T3), and 40 (T4) min. Results: There was a significant decrease between T0 and T1 in heart rate (80.5 ± 11.6 vs. 75.9 ± 14.4 beats/min), MAP (105.8 ± 21.9 vs. 78.9 ± 18.4 mmHg) and PSI (88.5 ± 8.3 vs. 30.3 ± 9.7) (all p

The aim of this study was to report our results of glucocorticoid therapy combined with pregabalin and a home exercise program in patients with frozen shoulder.Thirty-three patients (seven males, 26 females; mean age 52, range 43-71) diagnosed with primary idiopathic frozen shoulder were included in the study. Secondary causes and systemic diseases related to frozen shoulder were excluded. Administration of 0.5 mg/kg/day methylprednisolone was halved each week and ceased at the end of first month. Pregabalin, paracetamol and proton pump inhibitor was also included in the treatment. Physical therapy as a home program was initiated as the pain subsided. Patients were evaluated using the Constant, DASH and ASES scores in the sixth week and first year. Pain was evaluated with VAS and range of motion at each visit.Patients were followed up for an average period of 21 months (range 12-37). No adverse effect related to glucocorticoid therapy was observed during the treatment. The DASH, ASES and Constant scores improved significantly in the sixth week and first year (p 0.05). Average range of motion and pain improved significantly every week until full recovery (p 0.05).Glucocorticoid therapy combined with pregabalin and a home exercise program is an effective treatment in the first stage of frozen shoulder.

Transfer of the latissimus dorsi tendon to the posterosuperior part of the rotator cuff is an option in active patients with massive rotator cuff tears to restore shoulder elevation and external rotation. However, it is unknown whether this treatment prevents progression of cuff tear arthropathy.The purpose of this study was to determine whether the observed improvement in shoulder function in the early postoperative period with latissimus dorsi tendon transfer for irreparable rotator cuff tears will be permanent or will deteriorate in the midterm period (at 1-5 years after surgery).During a 6-year period, we performed 11 latissimus dorsi tendon transfers in 11 patients for patients with massive, irreparable, chronic tears of the posterosuperior part of the rotator cuff (defined as 5 cm supraspinatus and infraspinatus tendon tears with Goutallier Grade 3 to 4 fatty infiltration on MRI), for patients who were younger than 65 years of age, and had high functional demands and intact subscapularis function. No patients were lost to followup; minimum followup was 12 months (median, 33 months; range, 12-62 months). The mean patient age was 55 years (median, 53 years; range, 47-65 years). Shoulder forward elevation, external rotation, and Constant-Murley and American Shoulder and Elbow Surgeons scores were assessed. Pain was assessed by a 0- to 10-point visual analog scale. Acromiohumeral distance and cuff tear arthropathy (staged according to the Hamada classification) were evaluated on radiographs.Shoulder forward elevation, external rotation, Constant-Murley scores, and American Shoulder and Elbow Surgeons scores improved at 6 months. However, although shoulder motion values and Constant-Murley scores remained unchanged between the 6-month and latest evaluations, American Shoulder and Elbow Surgeons scores decreased in this period (median, 71; range, 33-88 versus median, 68; range, 33-85; p = 0.009). Visual analog scale scores improved between the preoperative and 6-month evaluations but then worsened (representing worse pain) between the 6-month and latest evaluations (median, 2; range, 0-5 versus median, 2; range, 1-6; p = 0.034), but scores at latest followup were still lower than preoperative values (median, 7; range, 4-8; p = 0.003). Although acromiohumeral distance values were increased at 6 months (median, 8 mm; range, 6-10 mm; p = 0.023), the values at latest followup (median, 8 mm; range, 5-10 mm) were no different from the preoperative ones (mean, 7 mm; range, 6-9 mm; p 0.05). According to Hamada classification, all patients were Grade 1 both pre- and postoperatively, except one who was Grade 3 at latest followup.The latissimus dorsi tendon transfer may improve shoulder function in irreparable massive rotator cuff tears. However, because the tenodesis effect loses its strength with time, progression of the arthropathy should be expected over time. Nevertheless, latissimus dorsi tendon transfer may help to delay the need for reverse shoulder arthroplasty for these patients.Level IV, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

Anconeus interpositional arthroplasty has been used in the treatment of radiocapitellar and radioulnar joint problems occurring after trauma. A 31-year-old male patient developed heterotopic ossification (HTO) in the elbow following surgical treatment of an isolated radial neck fracture. Treatment with implant removal and excision of the radial head resulted in recurrent HTO and a stiff elbow. We performed anconeus interposition arthroplasty with excision of the heterotrophic new bone and mobilization of the proximal radius. The anconeus muscle was mobilized and interposed between the proximal radius and ulna. Sixteen months after the operation, forearm rotation, elbow flexion and extension increased by 80°, 45°, and 60°, respectively. Control X-rays showed maintenance of the radiohumeral gap without any signs of HTO., Ankoneus interpozisyon artroplastisinin travma sonrası oluşan radikapitellar ve radioulnar eklem sorunlarının tedavisinde kullanılabileceği bildirilmiştir. Bu yazıda, ankoneus interpozisyon artroplastisi ile tedavi edilen 31 yaşında bir erkek hasta sunuldu. Hastada radius boyun kırığı osteosentezi sonrasında heterotopik ossifikasyon (HTO) gelişmişti. Ossifikasyon odakları temizlenip radius başı eksize edildikten sonra HTO ve dirsek sertliği tekrarlayan hastaya, tekrar ossifikasyon eksizyonu sonrasında ankoneus kası ile interpozisyon artroplastisi uygulandı. Ameliyattan 16 ay sonraki kontrolde, önkol supinasyonu, dirsek fleksiyonu ve ekstansiyonunda sırasıyla 80, 45 ve 60 derece kazanım sağlandığı görüldü. Kontrol radyografilerinde HTO’nun tekrarlamadığı ve radioulnar ve radiokapitellar eklemlerin açık olduğu izlendi.

Objective: The aim of this study was to examine the radiological and clinical short term results of the patients who underwent reverse shoulder arthroplasty for rotator cuff arthropathy.Methods: The study included 14 (2 male, 12 female) patients who underwent reverse shoulder arthroplasty for rotator cuff arthropathy between 2009 and 2010. The mean age of the patients was 74 (57–80) years and the mean follow–up period was 32 (21–40) months. Radiological methods as well as the range of motion, Quick DASH, Constant and VAS scores were used for the evaluation of patients preoperatively and at last the follow–up.Results: Mean active forward flexion, abduction and external rotation increased respectively from 44, 41 and 21 degrees preoperatively to 149, 105 and 37 degrees at the last follow–up. The mean QuickDash score was 59.1 degrees preoperatively, and 36.1 degrees at the last follow–up visit. The mean Constant score increased from 20.7 preoperatively to 58.9 at the last follow–up visit. The mean VAS score decreased from 7 preoperatively to 1.2 at the last follow–up visit. The mean acromion–humeral head distance increased from 5.3 mm preoperatively to 23.1 mm postoperatively.

A 17-year-old boy who was engaged in amateur weightlifting and body building presented with complaints of right elbow pain and limitation in elbow range of motion. Plain x-rays and magnetic resonance imaging showed an osteochondral defect in the medial third of the capitellum. At surgery, as a new technique, the lateral collateral ligament was detached from the humeral attachment to provide access to the capitellum with a clear and perpendicular exposure. Following removal of loose fragments within the joint, an osteochondral graft harvested from the lateral femoral condyle was implanted to the defect area of the capitellum. Postoperative radiologic controls showed that the defect was entirely filled by the graft with appropriate graft height. On follow-up examination at 12 months, the patient did not have any complaint about his elbow, and had no limitation of movement compared to the left elbow. Magnetic resonance imaging showed that the graft was successfully adapted to the recipient site without any sign of loosening. At final follow-up 40 months after surgery, the surface of the articular cartilage appeared normal. The range of elbow motion was preserved and the patient had no restriction in daily and sports activities. Considering technical difficulties posed by the narrow and complex structure of the elbow joint, this new technique involving detachment of the lateral collateral ligament facilitates perpendicular implantation of the graft. In our opinion, utilization of this new technique will improve functional and radiological results of osteochondral autograft transfer., On yedi yaşında, amatör olarak ağırlık kaldırma ve vücut geliştirme sporu ile ilgilenen erkek hasta, sağ dirsekte ağrı ve hareket kısıtlılığı yakınmalarıyla başvurdu. Düz radyografilerde ve manyetik rezonans görüntülemede kapitellumun 1/3 orta bölgesinde osteokondral lezyon saptandı. Ameliyatta, yeni bir yaklaşım olarak, lateral kollateral bağ humeral yapışma yerinden kaldırılarak kapitellum daha net ve dik açıyla ulaşılabilecek pozisyona getirildi. Eklem içindeki serbest fragmanların çıkarılmasından sonra, lateral femoral kondilden alınan osteokondral otogreft defekt bölgesine yerleştirildi. Ameliyat sonrası radyolojik incelemelerde, osteokondral greftin defektli bölgeyi tam doldurduğu ve greft yüksekliğinin iyi olduğu gözlendi. Hastanın 12. ay kontrolünde dirsekte hiçbir yakınması ve sol dirseğe göre hareket kısıtlılığı yoktu. Manyetik rezonans görüntülemede greftin alıcı saha içine iyi uyum gösterdiği ve gevşeme belirtisi olmadığı görüldü. Kırk ay sonra yapılan radyografik kontrolde eklem kıkırdağının yüzey bütünlüğü normal görünümdeydi; hareket açıklığının korunduğu ve hastanın sportif ve günlük etkinliklerinde herhangi bir kısıtlaması olmadığı görüldü. Lateral kollateral bağı kaldırarak uyguladığımız cerrahi teknik, dirseğin dar ve karmaşık eklem yapısından kaynaklanan teknik zorluklar göz önüne alındığında, greftin dik açıda yerleştirilmesini kolaylaştırmaktadır. Bu teknikle yapılan osteokondral otogreft naklinin daha iyi fonksiyonel ve radyolojik iyileşme sağlayacağı kanısındayız.

Objective: The aim of this study was to assess the effects of coracoid bone block (modified Latarjet) procedure on clinical and functional results in cases with glenoid bone defect accompanied with anterior shoulder instability.Methods: The study included 35 patients (average age: 35 years; range: 20 to 58 years) with glenoid bone defect and recurrent dislocations treated with the modified Latarjet procedure. There were 12 sports injuries, 5 post-epileptic cases and 18 recurrent anterior shoulder dislocation following non-sports-related injuries. Recurrence was reported in 7 patients formerly treated with the Bankart procedure. Average number of preoperative dislocations was 10.8±6.5 and average time range between the first dislocation and surgery was 14.9±13.2 months. All patients underwent preoperative diagnostic arthroscopy. Postoperative isometric exercises in braces were assigned for the first 6 weeks, followed by active strengthening exercises. Pre- and postoperative functional results were evaluated using the ASES (American Shoulder and Elbow Surgeons) and Rowe scores and pain using the VAS (Visual Analog Scale).Results: Osseous union of coracoid graft was achieved in all patients. Average follow-up was 24±12.2 (range: 12 to 74) months. No degenerative arthritis or continuing instability was detected in any of the patients. Average forward flexion was 165°±20° and external rotation 59°±13°. Mean preoperative ASES and Rowe scores of 49.6±10.6 and 47.9±21.5 increased postoperatively to 91.3±11 and 89.1±9.2, respectively. Mean VAS scores decreased significantly from 6.2±2.4 to 1.8±0.6 postoperatively (p, Amaç: Bu çalışmanın amacı anterior omuz instabilitesine eşlik eden glenoid kemik defektli olgularda korakoid kemik blok (modifiye Latarjet) prosedürünün klinik ve fonksiyonel sonuçlara etkilerinin değerlendirilmesi idi.Çalışma planı: Tekrarlayan çıkık nedeniyle başvuran ve modifiye Latarjet prosedürü ile tedavi edilen, glenoid kemik defektli 35 hasta (ortalama yaş: 35, dağılım: 20-58) çalışmaya alındı. On iki hastada spor travması, 5’inde epilepsi nöbetleri sonrası, 18’inde ise spor dışı travma sonrası tekrarlayan anterior omuz çıkığı hikayesi mevcuttu. Daha önce Bankart onarımı uygulanan 7 hastada nüks vardı. Hastaların ameliyat öncesi ortalama çıkık sayısı 10.8±6.5, ilk çıkıktan ameliyata kadar geçen ortalama süre ise 14.9±13.2 ay olarak kaydedildi. Girişim öncesinde tüm hastalara tanısal artroskopi yapıldı. Hastalara ameliyat sonrası ilk 6 hafta askı içinde izometrik egzersizler, sonrasında aktif güçlendirme egzersizleri uygulandı. Ameliyat öncesi ve sonrası fonksiyonel sonuçlar ASES (American Shoulder and Elbow Surgeons) ve Rowe skorları ile, ağrı ise VAS (Visual Analog Scale) ile değerlendirildi.Bulgular: Ortalama 24±12.2 (dağılım: 12-74) ay takip edilen hastaların tümünde greft kaynaması sağlandı. Hiçbir hastada dejeneratif artrit bulgusu ve devam eden instabilite saptanmadı. Ortalama öne fleksiyon 165°±20°, dış rotasyon 59°±13° olarak ölçüldü. Ameliyat öncesi ASES ve Rowe skorları, sırasıyla, ortalama 49.6±10.6 ve 47.9±21.5 iken bu değerlerin son kontrollerinde 91.3±11 ve 89.1±9.2’ye yükseldiği görüldü. Hastaların ortalama VAS skorları ise 6.2±2.4’ten iken ameliyat sonrasında 1.8±0.6 değerlerine geriledi (p

We reviewed 17 patients with distal intraarticular humeral type C fractures, treated by open reduction and internal fixation, followed by an early rehabilitation programme. The results, as judged by the criteria of Jupiter, were excellent in ten, good in five and fair in two. Non-union of the olecranon osteotomy occurred in one patient.

We report a case of stress fracture of the clavicle in which diagnosis was delayed due to the unusual localization of pain and absence of predisposing risk factors. A 34-year-old woman presented with severe right-sided pain in the shoulder, arm, neck, and hemithorax, and numbness in her right upper extremity. Systemic radiographs, cervical and brachial plexus magnetic resonance imaging (MRI) and thorax computed tomography (CT) did not show any pathology. In a retrospective review of the shoulder MRI sections, an edematous appearance was noted in the right clavicle and adjacent soft tissues, suggesting a stress fracture of the clavicle. The patient was followed-up with activity limitation and analgesic treatment and her complaints subsided gradually. Control radiographs obtained 10 months later showed fracture healing with atypical callus formation. Stress fractures of the clavicle must be kept in mind in the differential diagnosis of shoulder pain presenting as an atypical severe arm pain radiating to the upper extremity and hemithorax. In suspected cases, it may be helpful to obtain CT and MRI sections parallel to the long axis of the clavicle., Risk faktörü bulunmaması ve ağrının atipik yeri nedeniyle klavikula stres kırığı tanısı geç konan bir olgu değerlendirildi. Otuz dört yaşında kadın hasta sağ tarafta şiddetli omuz, kol, boyun ve hemitoraks ağrısı ve sağ üst ekstremitede uyuşma yakınmaları ile başvurdu. Hastanın radyografilerinde, boyun ve brakiyal pleksusa yönelik manyetik rezonans (MR) ve toraks bilgisayarlı tomografi (BT) incelemelerinde patoloji görülmedi. Geriye dönük yapılan incelemede, sağ omuz MR görüntüsünde klavikula ve çevre yumuşak dokularda ödem saptanarak klavikula stres kırığı düşünüldü. Aktivite kısıtlaması ve analjezik tedavi ile hastanın yakınmaları kademeli olarak geriledi ve 10. aydaki kontrol tomografisinde stres kırığının aberan kallus oluşumu ile iyileştiği görüldü. Omuz ağrısı nedenleri arasında klavikula stres kırığı da akılda tutulmalı ve sorunun omuzdan üst ekstremiteye ve hemitoraksa yayılan atipik şiddetli bir ağrı ile ortaya çıkabileceği unutulmamalıdır. Şüphelenilen olgularda BT ve MR incelemelerinde kesitlerin klavikulanın uzun eksenine paralel olarak alınması yararlı olabilir.

Platelet-rich plasma (PRP) is a natural concentrate of autologous growth factors now being widely tested in different fields of medicine for its potential in enhancing the regeneration of tissue with low healing potential. However, studies of PRP in enhancing rotator cuff repair have been contradictory, perhaps because of how PRP is administered. The purpose of this study is to evaluate the effect of PRP and compare two different application methods of PRP on rotator cuff healing. The supraspinatus tendons of 48 mature, male Wistar–Albino rats were detached from their insertion on the humerus. The animals were divided into four groups: (1) no repair, (2) primary repair, (3) repair plus PRP injections into the tendon–bone interface, and (4) repair plus PRP absorbed from a sponge carrier to the tendon–bone interface. The tendons were evaluated biomechanically and histologically at week 8. Cuffs repaired with PRP had significantly greater mean (SD) load-to-failure rates [11.1 (6.5) and 11.6 (3.9) N; P

Coronal plane fractures of the distal humerus involving the capitellum and trochlea are rare. Treatments have evolved from closed reduction to open reduction and internal fixation (ORIF) to achieve a stable joint that allows early mobilization.We determined the functional outcomes of treating coronal plane fractures of the distal humerus with ORIF.We reviewed the records of all patients with coronal plane fractures of the distal humerus treated by ORIF. Fractures were classified according to Bryan and Morrey. Cannulated screws were used for fixation. All patients were evaluated using the Mayo Elbow Score Performance Index (MEPI) and disabilities of the arm, shoulder, and hand (DASH) scores at least 1 year later.Of the 18 patients evaluated (12 women), the mean (SD) age was 45.3(16.5) years (range 16-70). There were seven Type-I, five Type-III, and six Type-IV fractures. Mean follow-up was 43.6 (38.1) months (range 12-120). The mean elbow range of motion in sagittal plane at last follow-up ranged from 8.9° to 132.8°. The mean MEPI score was 86.7 (15.2) points (range 60-100), corresponding to 12 excellent, 2 good, and 4 fair outcomes. The mean DASH score was 15.3 (13.5) points (range 17-35.8). Heterotrophic ossification developed in one patient with delayed fixation; 14 patients with excellent or good results returned to their previous activity levels. Functional scores did not differ by age, sex, or fracture types (P0.05 for all comparisons).ORIF with cannulated screws, which maintain a stable anatomic articular position, provides satisfactory results in coronal plane fractures of the distal humerus.Level IV case series.

The purpose of this study is to evaluate the biomechanical properties and the stability among a locking clavicle plate (LCP), a dynamic compression plate (DCP) and an external fixator (Ex-fix) in an unstable displaced clavicle fracture model under torsional and three-point bending loading.Forty-eight human adult formalin-fixed clavicles were paired according to their bone mineral density homogeneously into three groups: LCP, DCP, and Ex-fix. Each specimen was osteotomized at the midshaft. Torsional and three-point bending forces were performed for 1000 cycles with stiffness recorded at 10 cycles (initial) and then at 100-cycle intervals thereafter. Initial stiffness, failure loads, and the percentage of initial stiffness at the various intervals were compared using analysis of variance.The mean initial stiffness values (Nmm/deg) for torsion were 703.2 (LCP), 448.1 (DCP), and 365.2 (Ex-fix). The mean failure moments (Nmm) for torsion were 7671.7 (LCP), 4370.3 (DCP), and 2999.7 (Ex-fix). The mean initial stiffness (Nmm) for bending were 32.6 (LCP), 23.4 (DCP), and 20.6 (Ex-fix). The mean failure loads (N) for bending were 213.2 (LCP), 131.1 (DCP), and 102.7 (Ex-fix). For both torsion and bending, an overall significant difference among the three constructs in terms of failure loads and also a significant difference between the locking plate and the other two models only in terms of initial stiffness was seen. For torsion and bending, at all cyclic intervals, there was a significant difference between the locking plate and the other two models. After 700 cycles, a significant difference was also detected between the DCP and Ex-fix in torsion, but no difference was found between these groups at any cyclic interval in bending.The locking plate is significantly more stable than DCP and Ex-fix under torsional and bending cyclic loading in a displaced fracture clavicle model.

Objectives: Although conventional suture techniques yield satisfactory results in the treatment of meniscal ruptures, they are inherent with long operative time and high complication rates. The purpose of this study was to evaluate the results of meniscal repair with the use of the RapidLoc device.Methods: The study included 57 consecutive patients (all males; mean age 24 years; range 17 to 33 years) who underwent meniscal repair with the RapidLoc device. The mean time from injury to surgery was 20 days (range 7 to 60 days). The mean length of meniscal ruptures was 25 mm (range 10 to 35 mm). A mean of two RapidLoc fixators were used for each rupture. Thirty patients had associated anterior cruciate ligament (ACL) rupture; of whom 17 patients underwent ACL reconstruction with hamstring autografts. Thirteen patients refused ACL reconstruction and underwent only meniscal repair. Functional results were evaluated using the Tegner activity score, Lysholm score, and IKDC (International Knee Documentation Committee) subjective knee evaluation form.Clinical assessments were made using the Barrett criteria. The mean follow-up was 39 months (range 18 to 66 months).Results: The mean operation time including diagnostic and surgical arthroscopy was 25 minutes (range 15 to 35 min). Compared to the preoperative scores, all functional scores showed significant improvements (p, Amaç: Menisküs tamirlerinde konvansiyonel dikiş yöntemleri ile oldukça tatminkar sonuçlar elde edilmesine karşın, bu yöntemlerde ameliyat süresi uzun ve komplikasyon oranı yüksektir. Bu çalışmada, RapidLoc fiksatörü kullanılarak yapılan menisküs tamirlerinin klinik sonuçları değerlendirildi.Çalışma planı: Çalışmaya RapidLoc fiksatörü ile menisküs tamiri yapılan ardışık 57 hasta (hepsi erkek; ort. yaş 24; dağılım 17-33) alındı. Travma ile ameliyat arasında geçen süre ortalama 20 gün (dağılım 7-60 gün) idi. Ortalama yırtık uzunluğu 25 mm (dağılım 10-35 mm) idi. Her bir yırtık için ortalama iki adet (dağılım 1-3) RapidLoc fiksatörü kullanıldı. Ön çapraz bağ (ÖÇB) yırtığı olan 30 hastanın 17’sine, menisküs tamiri ile beraber hamstring otogreft ile ÖÇB rekonstrüksiyonu yapıldı; 13 hastaya ise rekonstrüksiyon istemedikleri için sadece menisküs tamiri yapıldı. Hastalar Tegner aktivite skoru, Lysholm skoru ve IKDC (International Knee Documentation Committee) subjektif diz değerlendirme formuna göre değerlendirildi. Klinik değerlendirmede Barrett ölçütleri kullanıldı. Ortalama takip süresi 39 ay (dağılım 18-66 ay) idi.Sonuçlar: Menisküs tamiri sırasında tanısal ve cerrahi artroskopiyi içeren toplam ameliyat süresi ortalama 25 dakika (dağılım 15-35 dk) idi. Ameliyat öncesine göre tüm fonksiyonel sonuçlarda anlamlı düzelme görüldü (p

Objectives: We evaluated the contribution of subacromial local anesthetic and corticosteroid injection to the conservative treatment of subacromial impingement syndrome.Methods: The study included 56 patients (39 women, 17 men; mean age 50 years; range 31 to 68 years) with subacromial impingement syndrome without any rotator cuff lesion. The patients were randomly allocated to injection and control groups equal in number. The former group received a single subacromial injection of 9 ml bupivacaine and 1 ml betamethasone at the beginning of the treatment. The same physical therapy and rehabilitation program was administered to both groups, consisting of 15 sessions (3 weeks). Evaluations were made before, and three and six weeks after treatment. Functional results were assessed using the Constant score, pain was assessed using a visual analog scale, and range of motion was measured with a goniometer.Results: Compared to pretreatment values, both groups exhibited significant improvements in pain score, Constant score, and range of motion measurements at three and six weeks (p0.05). Patients receiving subacromial injection had significantly higher Constant scores at six weeks (p=0.044) and significantly greater external and internal rotation at three weeks (p=0.03). Range of motion measurements did not differ between the two groups at six weeks (p>0.05).Conclusion: Subacromial injection contributes to the success of the conservative treatment through decreasing pain and enabling more effective range of motion and strengthening exercises, both of which are associated with increased functional improvement., Amaç: Lokal anestetik ve kortikosteroid enjeksiyonunun subakromiyal sıkışma sendromunun konservatif tedavisine katkısı araştırıldı.Çalışma planı: Çalışmaya subakromiyal sıkışma sendromu tanısı konan ve rotator manşet lezyonu olmayan 56 hasta (39 kadın, 17 erkek; ort. yaş 50; dağılım 31-68) alındı. Hastalar enjeksiyon grubu ve kontrol grubu şeklinde rastgele seçimle eşit sayıda iki gruba ayrıldı. Enjeksiyon grubuna tedavinin başında subakromiyal enjeksiyonla 9 ml bupivakain ve 1 ml betametazon uygulandı. Tüm hastalara üç hafta süreli (15 seans) aynı fizik tedavi ve rehabilitasyon programı uygulandı. Değerlendirmeler tedaviden önce ve tedaviden üç ve altı hafta sonra yapıldı. Fonksiyonel durum Constant skoru, ağrı görsel analog skala ile değerlendirildi ve eklem hareket açıklığı gonyometre ile ölçüldü. Sonuçlar: İki grupta da üçüncü ve altıncı haftalarda tedavi öncesine göre ağrı skorunda, Constant skorunda ve eklem hareket açıklığı ölçümlerinde anlamlı düzelmeler elde edildi (p0.05). Enjeksiyon grubunda altıncı haftada Constant skoru (p=0.044) ve üçüncü haftadaki dış ve iç rotasyon değerleri (p=0.03) kontrol grubuna göre anlamlı derecede yüksek bulundu. Altıncı haftadaki hareket açıklığı ölçümlerinde gruplar arasında anlamlı fark bulunmadı (p>0.05). Çıkarımlar: Subakromiyal enjeksiyon uygulaması ağrıyı önemli derecede azaltarak, eklem hareket açıklığı ve güçlendirme egzersizlerinin daha etkili olarak yapılmasına ve fonksiyonel sonuçların daha başarılı olmasına katkıda bulunmaktadır.

Synovial chondromatosis, is the chondroid metaplasia of the synovial membrane. Large joints such as the knee and hip are most commonly involved. Extraarticular involvement is rarely described. Synovial chondromatosis may be associated with impingement syndrome of the shoulder. We report a case of synovial chondromatosis of the subcoracoid bursa, which resulted in impingement symptoms.

Objectives: Biodegradable poly L-lactic acid (PLLA) fixators used in the repair of meniscal tears may cause adverse reactions inside the knee due to delayed degradation. This study was designed to determine the reasons for late degradation of PLLA fixators.Methods: Three unused and three used meniscal PLLA fixators (BioStinger) were analyzed. The latter were removed from three patients due to persisting symptoms within six months after knee arthroscopy. Fourier transform infrared (FTIR) spectroscopy was performed and external and internal surfaces of the samples were examined by scanning electron microscopy (SEM) and X-ray fluoroscopy (XRF). Chemical structural analyses of two samples (one from each group) were made by 1 H-nuclear magnetic resonance (1 H-NMR) spectroscopy. Degradation times of two samples (one from each group) by oxidative hydrolysis in hydrogen peroxide solution were recorded.Results: Chemical structure of used and unused fixators did not differ in FTIR analysis. With increasing temperatures, unused and used fixators showed degradation with and without melt flow, respectively. In SEM analysis, inner sections of unused fixators were homogeneous, whereas those of the used ones exhibited crystals which were found to be sodium and potassium chloride salts in XRF analysis. The 1 H-NMR spectrum of used and unused samples showed the normal pattern of lactic acid polymer. The unused and used fixators degraded in hydrogen peroxide solution in 10 days and 30 days, respectively.Conclusion: Both fixators had the same chemical structure in FTIR and NMR analyses. Formation of salt crystals seemed to be the most important cause of degradation failure, while changes in the physical properties of fixators were thought to be associated with delayed degradation., Amaç: Menisküs yırtıklarının tamirinde kullanılan biyobozunur poli L-laktik asit (PLLA) sabitleyicilerden bazıları erimeyip diz içinde birtakım reaksiyonlara neden olabilmektedir. Bu çalışmada PLLA sabitleyicilerin geç erime nedenleri araştırıldı.Çalışma planı: Çalışmada hiç kullanılmamış üç adet ve diz artroskopisinden sonra altı ay içinde üç hastada semptomların tekrarlaması nedeniyle çıkarılan üç adet PLLA sabitleyici (BioStinger) Fourier transformed infrared (FTIR) spektrometresi ile incelendi. Okların dış ve iç yüzeyleri taramalı elektron mikroskobu (TEM) ve X-ışını fluoroskopisi (XRF) ile incelenip, yüzeylerin fotoğrafları çekildi. İki gruptan birer sabitleyicinin 1H-nükleer manyetik rezonans (1H-NMR) spektrometresi ile yapısal analizi yapıldı. Ayrıca, birer sabitleyici hidrojen peroksit solüsyonu içinde bekletilerek oksidatif hidroliz süreleri kaydedildi.Sonuçlar: FTIR analizinde sabitleyiciler kimyasal yapı bakımından farklılık göstermedi. Tüm sabitleyiciler sıcaklık artışı ile bozunuma uğradı; ancak yeni sabitleyiciler akma gösterirken, kullanılmış olanlar akma göstermedi. Taramalı elektron mikroskopisinde yeni sabitleyicilerin iç yüzeylerinin kesiti homojen görünümde idi; kullanılmışlarda ise kristaller gözlendi. XRF’de bu kristallerin potasyum ve sodyum tuzları olduğu görüldü. 1H-NMR ile incelenen örneklerin ikisi de normal yapıda laktik asit polimeri idi. Yeni sabitleyici hidrojen peroksit içinde 10 günde, kullanılmış olan 30 günde eridi.Çıkarımlar: İki gruptaki sabitleştiriciler arasında, FTIR ve NMR incelemelerinde kimyasal yapı bakımından fark bulunmadı. Kullanılmış sabitleyicilerde oluşan tuzlanma erimeme nedenlerinin en önemlisi olarak kabul edilirken, fiziksel özelliklerindeki değişimlerin de erimeyi geciktirdiği düşünüldü.

Patients with facioscapulohumeral dystrophy (FSHD) are affected mostly by impaired shoulder function. Scapulothoracic arthrodesis was introduced to improve shoulder function. We evaluated the outcomes of scapulothoracic arthrodesis using multifilament cables, performed on 13 patients with FSHD (18 shoulders). There were eight males and five females (mean age, 29 years; range, 20-50 years). Outcome criteria were active shoulder forward flexion and abduction, the Disabilities of the Arm, Shoulder, and Hand (DASH) score, respiratory function tests, and a new shoulder function score. Patients were followed for a minimum of 24 months (average, 35.5 months; range, 24-87 months). Solid fusion was obtained in all shoulders (two after revision); active abduction range increased from 47.2 degrees +/- 11.6 degrees to 102.2 degrees +/- 10.0 degrees (mean +/- standard deviation) and anterior flexion range from 55.6 degrees +/- 16.1 degrees to 126.1 degrees +/- 20.9 degrees . The DASH score decreased from 33.6 +/- 8.9 points preoperatively to 11.6 +/- 8.0 points postoperatively. Shoulder function score increased from 15.9 +/- 2.4 points to 22.2 +/- 1.3 points. Scapulothoracic arthrodesis provides satisfactory function in patients with FSHD. Our data suggest use of multifilament cables for fixation is a reasonable option with an acceptable complication rate.Level IV, case series.
