- Abstract
Background: In this study, it was aimed to evaluate the patients who underwent cable plate fixation due to a Vancouver-type B1 periprosthetic femur fracture and their clinical results., Methods: Vancouver-type B1 patients who were operated on for periprosthetic fractures between 2014 and 2019 were investi-gated. Age, gender, body mass index (BMI), follow-up time, operation time, bleeding amount, non-union fracture, last surgery before fracture, the time between previous surgery and fracture, implant survival, patient survival, and complications were recorded. In addi-tion, the postoperative clinical functions of these patients were compared., Results: 23 patients who met the study criteria (Vancouver type B1 fracture) were identified. The mean age of the patients was 60 (49-76) years, the mean BMI was 26.3 (17.5-40.7), and the postoperative mean follow-up period was 14 (6-36) months. Considering the gender distribution, there were 5 (22%) men and 18 (78%) women. The mean time between the last surgery before the fracture and the fracture was 6 months (0-30). While the mean operation time was 95 min (60-180), the average amount of bleeding was 310 mL (150-600). Functional evaluations of patients: In total, five patients had decreased ambulatory abilities after surgery. Nonunion was observed in 2 patients during the follow-ups, and these patients underwent open surgery for treatment., Conclusion: Cable and locking plate applications are successful in Vancouver type B1 fractures, which are one of the most common forms of periprosthetic fractures. In this technique, the duration of the operation can be shortened under ideal conditions, and the need for blood and blood products is reduced as blood loss is reduced. If there is a complication, you still have the chance to treat it with the option of revision arthroplasty.

- Abstract
Introduction In this study, we aimed to compare the clinical and radiological results of patients who underwent medial retinaculum plication (MRP) combined with lateral retinacular release (LRR) or lateral retinacular lengthening (LRL) with the diagnosis of patellofemoral (PF) instability. Methods In our study, we retrospectively analyzed 75 knees of 75 adult patients (43 females and 32 males) who underwent MRP+LRR or MRP+LRL due to PF instability without osseous pathologies. Patients were divided into two groups (MRP+LRR and MRP+LRL) according to the surgical method. The clinical and radiological results of the two groups were compared. Results MRP+LRL surgery was performed on 45 knees and MRP+LRR surgery on 30 knees. The mean age was 26.5 (18-43) years. There was no significant difference between the two groups in the change in patellar lateral shift (PLS) (p=0.429) and congruence angle (CA) (p=0.218) values. However, there was a significant difference between the two groups in the change in patellar tilt angle (PTA) (p=0.009) and lateral patellofemoral angle (LPFA) (p<0.001) values. The change in PTA and LPFA values was higher in the MRP+LRL group. There was no significant difference between the two groups in terms of pre-operative and post-operative Lysholm knee scoring scale (p=0.205, p=0.228), Kujala pain scale (p=0.393, p=0.596), and Tegner activity level scale values (p=0.121, p=0.899). Conclusions MRP+LRR or MRP+LRL provided successful results for correcting the instability in PF instability without osseous pathologies such as patella alta, tibial tubercle-trochlear groove (TT-TG) dysplasia, trochlea dysplasia, genu valgus, and tibial-femoral torsion. While PTA and LPFA values improved more with the MRP-LRL method, clinical results were similar in both methods., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Saylik et al.)

- Abstract
Objectives: In this study, we aimed to evaluate the outcomes of patients undergoing unilateral knee arthroplasty (UKA) and to analyze risk factors that may lead to revision in patients who undergo UKA., Methods: We included patients who underwent mobile or fixed UKA owing to osteoarthritis and who had at least 24 months of follow-up in the postoperative period. We recorded information on patient age, sex, side, body mass (kg/m
2 ), follow-up duration, Knee Society Score, Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain, WOMAC function, WOMAC stiffness, mechanical axle angle, femoral component compliance, tibial component compliance, accumulated experience of the surgeon, and revision status., Results: In total, we evaluated 131 knees in 118 patients. 50 (38%) who underwent mobile UKA and 81 (62%) who underwent fixed UKA. The effect of obesity on mobile and fixed UKA revision was significant. The likelihood of revision decreased with greater experience of the surgeon performing UKA., Conclusion: Our study showed that the clinical results of mobile and fixed UKA procedures are similar. We also revealed that obesity poses a risk for revision in both fixed and mobile UKA, and the revision rate decreases with increased experience of the surgeon.- Published

- Abstract
Management of pediatric pulseless supracondylar humerus fractures is a point of continuous debate. In this article, we present three cases admitted to the emergency department with pulseless, but well-perfused hands. The fractures were reduced and fixed using the antecubital approach. Prior to reduction, the brachial arteries of all three patients were entrapped in the cancellous bone of the proximal fragment segment. The arteries could only be released after freeing the adventitia by carefully scraping the adjacent bone with the tip of a hemostat. One case required thrombectomy through an arteriotomy using No. 3 Fogarty catheter. In two cases, the pulse returned after a brief period of waiting with no need for vascular intervention. Proceeding with closed reduction, as proposed by the recent guidelines, would result in further damage to the entrapped vasculature, which may go unnoticed due to collateral circulation.

- Abstract
Background: Proximal humerus fractures are quite common, constituting 5% of all fractures. Plate osteosynthesis of comminuted fractures in the elderly with osteoporotic bones is prone to complications, including loss of reduction, intraarticular protrusion of screws, avascular necrosis and non-union. Hemiarthroplasty may be preferred to achieve a stable fixation, which permits early shoulder motion. Prerequisites for the successful functional outcome of this surgical technique are to have an intact rotator cuff, which is often torn, and achieve proper soft tissue balance, which is technically demanding. In RSA design, deltoid muscle replaces the function of the supraspinatus, compensating for a dysfunctional rotator cuff or a displaced tuberculum. We designed a retrospective study to evaluate the results of proximal humerus fractures treated with reverse shoulder arthroplasty using Humelock II reversible prosthesis in elderly patients., Methods: Thirty-one patients (25 females, six males) above 65 years old who underwent reverse shoulder arthroplasty between 2014 and 2019 for Neer 3-4 part fractures or head split injuries were included in this study. Patients with a previous internal fixation attempt, cases with neurological deficit or previous upper extremity fractures, patients who presented later than three weeks after the trauma, cases with less than six months follow-up and patients with additional fractures were excluded. Twenty-eight patients were available for final analysis. Fracture mechanism, time from trauma till surgery, hospital stay and preoperative ASA scores were noted. Humelock II Reversible (FX Solutions) implants were used in all cases. Patients' shoulder range of motion and functional outcome using UCLA, DASH and Constant scores at minimum six months follow-up were evaluated., Results: The mean age was 72.2 (65-95) years, and mean follow-up time was 15.5 (6-48) months. The mean UCLA, Constant and Dash scores at the last follow-up were 27.6 (14-35), 67.9 (38-80) and 30.8 (9.9-79.2), respectively. Mean shoulder flexion, abduction, internal and external rotation were 130 (110-160), 100 (70-140), 40 (15-60) and 39 (15-75) degrees, respectively., Conclusion: RSA is a very reliable treatment for proximal humerus fractures in patients over 65 years old. Early active and passive shoulder exercises can be started postoperatively, and good functional outcome and wide ROM can be achieved with this age group. Although stable fixation of the tuberculum is not required for shoulder abduction, it facilitates external rotation and should be attempted in all cases. Clinical outcomes of patients who underwent RSA due to proximal humerus fracture are as good as the outcomes of patients with different etiologies.

- Abstract
Objective: The aim of this study was to compare the efficacy of popliteal artery and the capsule of the posterior knee (IPACK) block and genicular nerve block on postoperative pain scores, the need for rescue analgesics, range of motion (ROM), walking distance, and perioperative monitorization variables in patients undergoing total knee replacement (TKR) surgery., Methods: Sixty American Society of Anesthesiologists (ASA) physical status I-III patients were enrolled in this study and then were randomly assigned into three groups: the IPACK block group (17 female, 3 male; mean age=67.5±1.4 years), genicular nerve block (16 female, 4 male; mean age=68±1.76 years), and the control group (13 female, 7 male; mean age=63±1.67years). All the patients underwent TKR under spinal anesthesia. The visual analog scale (VAS) score, mobility, pre- and intra-operative monitorization of systolic and diastolic holding area, non-invasive blood pressure, heart rate, and SPO 2 were compared between the groups., Results: Patients in the IPACK and genicular block groups had a significantly lower visual analogous scale (VAS) at postoperative 4 hours (p<0.01), 8h (p<0.01), 12h (p<0.01), and 24h (p<0.05). VAS score was significantly lower in the genicular block group at the postoperative 4h (5.5±0.55) and 8h (5.0±0.53) in the mobile state compared to the IPACK (8.0±0.47 and 8.0±0.43, respectively) and the control group (9.5±0.20; 10±0.28, respectively) (p< 0.01). The use of patient-controlled-analgesia (PCA) devices and button push count for analgesics demand were significantly lower in the genicular block group on the immediate postoperative period (p<0.01 at the postoperative 0 to 4 h). The total consumption of morphine equivalents on the postoperative day 0 was significantly lower in the genicular block group (p<0.01, and p<0.001 for IPACK and control groups, respectively). The degree of flexion was significantly higher in the genicular block group at the postoperative 12h compared to the IPACK and the control group (p<0.001). The length of hospital stay was significantly lower in the genicular block group compared to the IPACK and the control group (p<0.05 for both variables)., Conclusion: IPACK and genicular blocks both are effective in improving patient comfort during and after TKR surgery and reducing the potential need for systemic analgesic and opioids. The genicular block seems to be a promising technique that can offer improved pain management in the immediate and early postoperative period without adverse effects on systemic and motor variables.

- Abstract
Background: Anterior shoulder dislocation is the most common shoulder injury in patients presenting to the emergency department (ED). Up to 25% of these injuries are fracture-dislocations. In general, the standard approach is to obtain plain radiographs before and after reduction. Fresno-Quebec Rules (FQR) are described to identify the patients who require an x-ray before reduction to reduce radiation exposure and delays in treatment. We aimed to evaluate the efficacy of clinical predictors used in the Fresno-Quebec algorithm for detecting a shoulder fracture-dislocation., Methods: Records of patients who presented to the Emergency Department with presumed shoulder dislocation were retrieved and retrospectively analyzed according to 'Fresno-Quebec Rule (FQR)'. Sensitivity, specificity, and predictive values of FQR for detecting associated injuries were calculated., Results: Eighty-nine (65.9%) men and 46 (34.1%) women were included. The mean age of patients was 46 years (16-89). Ninety-nine (73.3%) of the cases had their shoulder dislocated for the first time, whereas 36 (26.7%) patients had a recurrent dislocation. Fifty percent of the patients (18 cases) with recurrent dislocation presented with an atraumatic episode. The remaining 18 patients with a history of recurrent dislocations had their shoulder dislocated as a result of trauma, and four (22%) of them had fracture-dislocation. Using the Fresno-Quebec rules yielded 100% specificity for the diagnosis of fracture-dislocation. The severity of the injury mechanism was not predictive in traumatic but recurrent dislocations. Only one of four patients with a fracture-dislocation in the traumatic recurrent dislocation group had high energy trauma., Conclusion: FQR has 100% sensitivity in detecting fracture-dislocations in patients admitted to ED with anterior shoulder dislocation. It utilizes simple parameters that are easy to use and recall. Using these rules, 30% of unnecessary radiographs can be avoided, saving time and money and reducing radiation exposure in anterior dislocations.

- Abstract
Head lice infestation caused by Pediculus humanus capitis De Geer, 1767 is one of the most common public health problems. The relationship between humans and head lice dates back millions of years ago that differentiated into different phylogenetic clades. Treatment of head lice infestation usually based on insecticide-based products, which promotes the resistance in the head lice populations. In the present study, we aimed to screen the presence of permethrin resistance among collected P. h. capitis specimens in Turkey. Three mutation sites (T917I, L920F, and M815I) were screened using real-time PCR and resistance was identified by melt analysis. Of the studied specimens, resistance allele frequency (RAF) was found 0.98 for T917I, 0.99 for L920F, and 1.00 for M815I. The phylogenetic study revealed that Clade A and Clade B are present and overlap in Turkey. The present study is first to screen the resistance among Turkish head lice specimens. To not stimulate the pyrethroids resistance in head lice populations, early detection of resistance is crucial and will help the health professionals to choose suitable formula in the treatment. We suggest that the resistance status needs to be screened in randomly selected populations before any treatment application is given., Competing Interests: Declaration of Competing Interest On behalf of all authors, the corresponding author states that there is no conflict of interest., (Copyright © 2020 Elsevier B.V.

- Abstract
Objectives: This study aims to compare the antibiotic release and biological effectiveness of bead type and articulating spacers of different cement types with antibiotics added at alternative phases of cement preparation., Materials and Methods: Four gram vancomycin was added into two types of antibiotic-free cement (Simplex®, Biomet®) with similar viscosity and also gentamycin-containing cement (Refobacin®). Prepared specimens were used to create cement beads and articulating hip spacers, making a total of six different groups. Two alternative groups were formed by adding the Vancomycin while the cement was in dough phase. Antibiotic release and biological activity were evaluated with immunoassay techniques and agar-disk diffusion methods., Results: All groups showed initial antibiotics surge in the first week, which was 2 to 4 times more evident in the beads group. Antibiotic release and change in release rate were significantly different between Simplex-alternative and Simplex, Biomet, Refobacin-beads, and between Biomet-spacer and Refobacin-beads groups (p<0.05). Elution of antibiotics was not different between mobile spacers prepared with conventional or alternative methods (p>0.05). Biomet cement showed larger diffusion inhibition zone in agar. There was no difference between biological activity of the bead and mobile designs of the Biomet brand (p>0.05). Inhibition zone analyses of agar and disk diffusion tests revealed significant differences between several groups (p<0.05)., Conclusion: Cement beads provide superior antibiotic release regardless of cement type or preparation method. Simplex P® cement has lower anti-bacterial efficiency than Biomet®. Different methods for cement and antibiotics mixing and addition of extra vancomycin into the commercially drug loaded cement do not have any effect on the results.

- Abstract
Objective This study was performed to compare the clinical and radiological outcomes of displaced femoral neck fractures (FNFs) treated with either hemiarthroplasty or total hip arthroplasty (THA) in elderly patients. Morbidity and mortality were also evaluated. Methods Twenty-two patients who underwent hemiarthroplasty and 16 patients who underwent THA for treatment of Garden type 3-4 FNFs from 2012 to 2015 were enrolled in this study. All patients were >65 years of age. Cox regression analysis was performed for mortality evaluation. Results The postoperative blood loss volume, decrease in the hemoglobin level, and transfusion rate were significantly higher in the THA group. The univariate mortality risk was higher in patients with a Charlson comorbidity score of >4, American Society of Anesthesiologists score of >2, Singh index of <3, and postoperative hospitalization of >1 week. Conclusion This study revealed no significant difference in the short-term clinical and radiological results between cementless hemiarthroplasty and THA in elderly patients with displaced FNFs. However, morbidity and mortality were associated with the presence of additional systemic diseases. THA is the preferred surgical technique in patients with displaced FNFs and low comorbidities.

- Abstract
Objectives: This study aims to investigate whether the axial shape of the distal femur is different between normal and osteoarthritic female knees using statistical shape analysis., Patients and Methods: A total of 126 knee magnetic resonance images of 126 female patients were examined in this study conducted between May 2013 and May 2014. Patients were divided into two groups as study and control groups. The study group consisted of 41 patients (median age 65 years; min. 36 - max. 88 years) who were determined to have knee osteoarthritis, while the control group consisted of 85 patients (median age 43 years; min. 20 - max. 81 years) without knee osteoarthritis. Anatomic and constructive landmarks were selected and marked on each two-dimensional digital image in the axial section of the distal femur. The mean axial shapes of the distal femur were compared between the groups by statistical shape analysis. Shape deformations were investigated by thin plate spline analysis., Results: There were significant differences between the groups regarding the axial shape of the distal femur. Maximal deformation was observed in the femoral notch area., Conclusion: This study showed that there are deformations in the axial shape of the distal femur in female patients with knee osteoarthritis. Further studies are required to determine whether these differences are important for implant design and surgical technique of total knee replacement.

- Abstract
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<0.05). Five patients (71.4%) had excellent or good outcomes on the MEPI. The mean Q-DASH Score was improved from 93.2 to 34.5 (p<0.01). Two humeral components had aseptic loosening, and 1 of them was revised., Conclusion: Semiconstrained total elbow arthroplasty can be a reliable choice of treatment if other internal fixation methods fail. Significant pain relief and improvements in elbow function and stability can be achieved with semiconstrained elbow arthroplasty in patients with distal humeral nonunion.

- Abstract
Purpose: The purpose of the present study was to determine whether the axes aligned with the sulcus between the tibial spines and the middle of the posterior cruciate ligament at the knee and with the tibialis anterior tendon at the ankle provide a neutral rotational and coronal alignment of the tibial component in total knee arthroplasty (TKA)., Methods: In a cohort of 45 TKA patients, CT scans were taken to quantify coronal and rotational positioning of the components. All patients received a posterior stabilised total knee replacement with a fixed insert (PFC Sigma; DePuy Orthopaedics, Inc; Warsaw, IN, USA). The tibial guide was aligned with the sulcus between the tibial spines and the middle of the posterior cruciate ligament at the knee and with the tibialis anterior tendon at the ankle., Results: The average post-operative coronal mechanical alignment was 1° varus (range 4.5° varus-1.5° valgus; SD ±1.51). The average post-operative rotational deviation from the transepicondylar axes (TEA) was 0.78° of internal rotation (1.50° of internal rotation - 3.5° of external rotation) for the tibial component. The whole-extremity mechanical axis deviation was outside the tolerance range of 3° in 4 patients (8.9 %). Deviation of the tibial component rotational position relative to the TEA was 3° or less in 94.5 % of the patients., Conclusions: When the tibial component is aligned using the axis drawn from the centre of the PCL to the sulcus between the tibial spines on the proximal tibia and to the tibialis anterior tendon at the ankle, good alignment will be achieved in both the coronal and axial planes., Level of Evidence: IV.

- Abstract
Purpose: This study aimed to research which was the most reliable of the four techniques based on local anatomic markers used to determine tibial component rotation in total knee arthroplasty, and whether the markers varied in knees with varus deformity., Methods: The study included 33 knees with a normal anatomic axis and 32 knees with a varus deformity and osteoarthritis. On the MR images, the femoral transepicondylar axis (TEA) was determined and transposed to the standard tibial resection level. At this level, four axes were drawn on the axial sections: tibial posterior condylar line (PC), tibial plateau anterior line (AC), a vertical line (AA) drawn to Akagi's line, and the maximal mediolateral distance (MMLD). The relationships of these lines and the transposed TEA were compared between two groups., Results: In all the knees, the mean values of the PC, AA, and MMLD axes compared to TEA reference were 5.5° ± 5.7 (mean ± SD), 7° ± 3.2, and 6.7° ± 8.1 internal rotation, respectively, and the AC axis was 8.9° ± 6.7 external rotation. In the AC, AA, and MMLD axes, the change occured because of varus deformity was statistically meaningful. For all the observers, the axis with the least SD and the most accuracy was the AA axis., Conclusions: Of the four axes used to determine tibial component rotation, only the PC axis is not affected by varus deformity, and the least affected axis according to the observers was the AA axis, and thus the AA and PC axes can be used for guidance in determining the rotation of the tibial component., Level of Evidence: Prognostic studies-investigating natural history and evaluating the effect of a patient characteristic: High-quality prospective cohort study with >80% follow-up, and all patients enrolled at same time point in disease, Level I.

- Abstract
Objectives: The aim of the present study was to compare the scapular manipulation technique and the Kocher's method in terms of efficacy, safety, and the intensity of pain felt by the patient in the reduction of acute anterior shoulder dislocation., Patients and Methods: Between July 2009 and January 2010, a total of 64 patients with acute traumatic anterior dislocation of the shoulder were evaluated. Of the 64 patients assessed, three patients were excluded because of cardiopulmonary problems. The remaining 61 patients (41 males, 20 females; mean age 42±18.5 years; range 17 to 87 years) were enrolled in this prospective randomized study and divided into two groups. Thirty-one patients were treated with scapular manipulation (group 1) and 30 patients were treated by the Kocher's method (group 2). A procedural sedation/analgesia was applied before the reduction to meet the target sedation score of 1 or 2 according to the Ramsay sedation scale. A visual analog scale was used to determine the intensity of the pain felt by the patients during reduction., Results: Reduction was successfully achieved with the scapular manipulation method in 96.7% of the patients, and with the Kocher's method in 93.3% (p>0.05). The degree of pain experienced by group 1 was lower than group 2 (p<0.01)., Conclusion: Both scapular manipulation and Kocher's techniques are successful and reliable methods when procedural sedation/analgesia is used routinely. Scapular manipulation is a less painful method of reduction of an anterior shoulder dislocation in comparison with the Kocher's technique.

- Abstract
Background: We evaluated the results of intertrochanteric hip fractures treated with closed reduction and external fixation (minimally invasive and biological osteosynthesis) in patients with high surgical risk., Methods: Twenty-three patients (14 females, 9 males; mean age 74 [65-88]) with intertrochanteric hip fracture classified as group III and IV according to American Society of Anesthesiologists (ASA) criteria were treated with closed reduction and unilateral external fixation under short-term anesthesia. Fourteen fractures were stable (60.8%) and nine were unstable (39.2%). The mean follow-up was 23.8 months (4-58). We evaluated the operation time, hospitalization time, union time, mobilization capacity, complications, and mortality rates., Results: The mean duration of operation was 25 minutes (15-40), mean duration of hospital stay 4 days (2-9) and average union time 13 weeks. Five patients (21.7%) died due to additional health problems in the first six months after surgery. Superficial pin tract infection occurred in 11 cases (47.8%). There was no implant failure. In the last follow up, an average 5° varus (range: 0-8°) and 1 cm shortening (range: 0-3) in stable fractures and an average 15° varus (range: 8-20°) and 3 cm shortening (range: 2-5) in unstable fractures were determined., Conclusion: The treatment of intertrochanteric hip fractures with closed reduction and external fixation is an easy, effective and safe biological fixation method with minimal damage to surrounding tissues, especially in patients with high surgical risk.

- Abstract
Objectives: In this study, we investigated the radiologic changes of feet in sagittal plane under weightbearing either with or without plantar fasciitis., Methods: The study includes 64 feet of the 42 subjects with heel pain (Group 1: 32 women, 10 men, mean age 48 years, range 33-57 years) and 80 feet of the 40 patients (Group 2: 30 women, 10 men, mean age 47.2 years, range 35-56 years) without heel pain. Calcaneal inclination angle (CIA), calcaneal-first metatarsal angle (CMA), and plantar fascia length (PFL) were measured in the lateral radiographs of the weightbearing and non-weightbearing foot. The values of Group 1 and Group 2 were compared., Results: The mean CIA was 26° (range 18-35°), CMA was 121° (range 115-133°), and PFL was 131 mm (range 110-158 mm) in non-weightbearing position for Group 1. The mean CIA was 27° (range 17-38°), CMA was 122° (range 110-135°), and PFL was 136 mm (range 120-155 mm) in non-weightbearing position for Group 2. The mean CIA was 13.6° (range 5-25°), CMA was 138° (range 130-153°), and PFU was 143.8 mm (range 118-158 mm) in weightbearing position for Group 1. The mean CIA was 9.9° (range 4-25°), CMA was 145° (range 130-155°), and PFU was 151.4 mm (range 137-167 mm) in weightbearing position for Group 2. The difference between CIA, CMA, and PFL values were -13°, 17°, and 12 mm under condition of weightbearing and nonweightbearing position values for Group 1; and -17°, 23°, and 15 mm for Group 2. The differences were significant between weightbearing and non-weightbearing position values (p<0.05)., Conclusion: The reduced CIA, CMA, and PFL changes during weight bearing might show reduced foot mobility and plantar fascia elasticity, which may lead to posterior heel pain syndrome.

- Abstract
Background: The results of surgical treatment of ankle fractures and influential factors were evaluated., Methods: The study ( 1999-2003) included 40 patients (28 men, 12 women) with a mean age of 37.7 years (15-83) who underwent surgical treatment for ankle fractures. The mean follow-up period was 29.6 months (5-66) According to Lauge-Hansen classification, the mechanism of occurence was supination-external rotation in 21 (52.5%), pronation-external rotation in 8 (20%) and supination-adduction in 5 (12.5%) patients, while 6 patients (15 %) were not assessed. Fractures were also classified (Danis-Weber ) as Type A (n= 8; 20%) , B (n = 22; 55%) and C (n =10; 25%) , including 35 (87.5%) bimalleolar fractures. Roberts criteria were used for the final evaluation of the patients., Results: Satisfactory union was obtained in all fractures. According to objective criteria, the results were good in 33 (82.5%) , moderate in 3 (7.5%) and poor in 4 (10%) patients, while corresponding subjective results were obtained in 34 (85%), 3 (7.5%) and 3 (7.5%) patients respectively., Conclusions: Improved outcomes can be obtained by anatomical reduction and restoration of the ankle joint, and the tilt of talus, fibular shortening and the dysfunction of the syndesmotic joint can be prevented. In our opinion our method of surgical treatment influenced better outcomes obtained.
