We present a case of polyarticular synovitis following alendronate treatment for osteoporosis. The patient had no evidence of rheumatoid arthritis, pyrophosphate arthropathy, or seronegative/seropositive arthritis. Our main aim in this study is to highlight the potential adverse effects of alendronate and to warn orthopedic surgeons about the possibility of such a side effect that might lead orthopedic surgeons to administer wrong and unnecessary treatments like arthrocentesis. The withdrawal of alendronate is found to be the treatment of choice. Alendronate should be considered as a possible cause of synovitis or polyarthritis in patients treated with this agent in the absence of any other pathology. An association between alendronate and synovitis has rarely been described in the literature. We present a patient who developed polyarticular synovitis after treatment with alendronate and responded to its withdrawal. [ABSTRACT FROM AUTHOR]

From 1992 to 1997 a series of 12 multiply operated (averaging 2.5 previous operations) patients with recurrent peridural fibrosis and postlaminectomy kyphosis underwent surgery at our clinic. The surgery was designed to restore the physiological lordosis and relax tethered cord and epidural veins by transpedicular decancellation osteotomy at a vertebra other than the vertebra with peridural fibrosis. This paper presents the long-term functional outcome of these 12 patients. Clinical assessments were conducted pre-operatively and at 3-month intervals postoperatively and included X-ray assessment and evaluation of the patients’ functional status by Oswestry Disability Index (ODI) and of pain by visual analogue scale (pain VAS). All symptoms and the pain due to peridural fibrosis disappeared in the early postoperative period. Patients had lower disability and pain scores at their early and long-term follow-ups (follow-up period 24–74 months, mean 36.3 months). For patients with failed medical therapy for peridural fibrosis accompanied by lumbar kyphosis or hypolordosis, transpedicular decancellation osteotomy should be the surgical treatment of choice.

Nuri Aydin,1 Kemal Gokkus,2 Cumhur Topal,1 Ahmet Turan Aydin21Uskudar State Hospital, Istanbul, Turkey; 2Memorial Antalya Hospital, Antalya, TurkeyAbstract: Solitary synovial osteochondromas are rarely seen. Usually arising from the juxta-articular soft tissues without attaching to the bone, these lesions can be large and show clinical and radiological features of a malignant process. This report is about a 64-year-old woman with no history of trauma. She had a history of dull pain and a progressive limited range of motion that had been ongoing for 3 years. An unusual presentation of an uncommon disease that is not widely known by orthopedic surgeons is reported.Keywords: solitary synovial osteochondroma, loose body, arthroscopy, knee joint, synovial chondromatosis

An introduction to the journal is presented in which the guest editors discusses the epiphyseal growth disorder of the skeleton which known as Trevor's disease or dysplasia epiphysealis hemimelica that dealt with by a resection.

Neglected bilateral posterior shoulder dislocation is a rare injury caused primarily by an epileptic seizure. The injury is usually associated with a reverse Hill-Sachs lesion in the anteromedial aspect of the humeral head. The modified McLaughlin technique may avoid instability and osteoarthritis when 20 to 40% of the articular surface is affected by reverse Hill-Sachs. In this article, we present the clinical results of a case overlooked in the literature for the longest time, i.e., for 15 months. A 46-year-old male patient was receiving treatment for epilepsy for five years. There was no fall or trauma in the four seizures he had during this time. The last seizure was 15 months ago. When the patient presented to our clinic, both shoulders were symmetrically deformed, the anterior shoulder contour disappeared (empty socket sign), and there was a loss of upper contour. The computed tomography (CT) scan revealed a posteriorly locked dislocation with a reverse Hill-Sachs lesion in 32% of the left shoulder and 36% of the right shoulder. We applied the modified McLaughlin procedure to the dominant right shoulder and, two months later, we used it to the left shoulder (with a graft taken from the anterior superior iliac spine). At one-year of follow-up, both shoulders were moderately functional: forward elevation left 70° and right 50°, abduction left 40° and right 60°, and internal rotation: the back of the hand could touch the fifth lumbar vertebra. Meanwhile, the patient did not suffer from recurrent dislocation. The pre- and postoperative Constant-Murley Scores for the right and left shoulder were 30/52 and 11/48, respectively. Although the operational outcomes using the modified McLaughlin technique were not ideal, with no recurrence, the patient seemed to be satisfied with this outcome. In conclusion, in neglected locked shoulder fracture-dislocations, the modified McLaughlin technique is a method that can respond to the pathophysiology by eliminating reverse Hill-Sachs lesion.

Chronic cases of peroneal subluxation typically call for surgical treatment; however, research on current surgical procedures suggests nonuniformity. The purpose of this study is to remind surgeons of the efficacy of an older surgical method by using the case of a selected patient. In this study, the Ellis Jones procedure was performed on a patient who had been suffering from a chronic peroneal subluxation for 22 years, since, in this particular case, other approaches were deemed likely to be unsuccessful. The patient had hypertrophied, frayed, and swollen tendons, which were unsuitable to be rerouted, whereas the superior peroneal retinaculum was diminished and deepening procedures would not be able to establish sufficient volume for retaining the hypertrophied tendons. After the debridement and repair of the peroneal tendons, ¼ of the lateral Achilles tendon was split, passed through a hole in the fibula, and sutured onto itself, and the subluxation path of the peroneal tendons was closed with an effective tendon barrier. The patient returned to work after 8 weeks of the surgery and was followed up for 4 years postoperatively. On selected patients, the Ellis Jones surgical method might therefore still be applied. Levels of Evidence: Level V.

Gold (Au) and silver (Ag) nanostructures have widespread utilization from biomedicine to materials science. Therefore, their synthesis with control of their morphology and surface chemistry have been among the hot topics over the last decades. Here, we introduce a new approach relying on sugar derivatives that work as reducing, stabilizing, and capping agents in the synthesis of Au and Ag nanostructures. These sugar derivatives are utilized alone and as mixture, resulting in spherical, spheroid, trigonal, polygonic, and star-like morphologies. The synthesis approach was further tested in the presence of acetate and dimethylamine as size- and shape-directing agents. With the use of transmission electron microscopy (TEM), selected area electron diffraction (SAED), x-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet-visible (UV-vis) absorption spectroscopy techniques, the particle size, shape, assembly, aggregation, and film formation characteristics were evaluated. NPs' attributes were shown to be tunable by manipulating the sugar ligand selection and sugar ligand/metal-ion ratio. For instance, with an imine side group and changing the sugar moiety from cellobiose to lactose, the morphology of the Ag nanoparticles (NPs) transformed from well dispersed cubic to rough and aggregated. The introduction of acetate and dimethylamine further extended the growth pattern and morphological properties of these NPs. As examples, L5 AS, G5AS, and S5AS ligands formed spherical or sheet-like structures when used alone, which upon the use of these additives transformed into larger multicore and rough NPs, revealing their significant effect on the NP morphology. Selected samples were tested for their stability against protein corona formation and ionic strength, where a high chemical stability and resistance to protein coating were observed. The findings show a promising, benign approach for the synthesis of shape- and size-directed Au and Ag nanostructures, along with a selection of the chemistry of carbohydrate-derivatives that can open new windows for their applications.

Introduction: Many orthopaedic procedures require drilling of bone, especially fracture repair cases. Bone drilling results in heat generation due to the friction between the bone and the drill bit. A high-level of heat generation kills bone cells. Bone cell death results in resorption of bone around bone screws. Methods: We searched in the literature for data on parameters that influence drilling bone and could lead to thermal necrosis. The points of view of many orthopaedists and neurosurgeons based upon on previous practices and clinical experience are presented. Results: Several potential complications that lead to thermal necrosis are discussed and highlighted. Discussion: Even in the face of growing evidence as to the negative effects of heat induction during drilling, simple and effective methods for monitoring and cooling in real-time are not in widespread usage today. For that purpose, we propose some suggestions for the future of bone drilling, taking note of recent advances in autonomous robotics, intelligent systems and computer simulation techniques. Conclusions: These advances in prevention of thermal necrosis during bone drilling surgery are expected to reduce the risk of patient injury and costs for the health service.

Trevor's disease, also known as dysplasia epiphysealis hemimelica, is a rare nonhereditary skeletal development disorder that affects epiphyses. This type of dysplastic lesion was first reported by Mouchet and Berlot in 1926 under the name 'tarsomegaly'. The main aim of this study is to raise awareness of Trevor's disease among orthopedic surgeons and underline some important aspects of treatment by a detailed presentation of four different possible manifestations of the disease. Four different treatment methods were used on four different patients (three localized in hindfoot ankle region and one classic Trevor's disease case). Treatment methods, localization of the sides involved, different characteristics of entire lower extremity, asymetry, distal femoral lateral epiphysis involvement, and hip involvement were analyzed thoroughly and the results were compared with those found in the most recent literature. Of our four patients, three were localized (hind foot ankle) cases and one was a classic dysplasia epiphysealis hemimelica with hemimelic distribution of the entire lower extremity. We used arthroscopic resection, observation, excision, and temporary hemiepiphysiodesis treatment methods in each of our cases. Clinical follow-up results were reported to be between good and excellent. In sum, our opinion is that the treatment for this condition should be customized according to lesion localization and lesion size. Majority of cases with ankle involvement show good prognosis following excision. Observation is also an alternative in patients who refuse surgery. If an intra-articular lesion is present, the surgeon should perform an arthroscopy for assessment of lesion surface. If the lesion is adapted to the joint curvature, it should be left alone and hemiepiphysiodesis should be considered for correction. The most risky involvements that are related to deformities and limb-length discrepancies are the hip and the knee. This is usually the result of corrective osteotomy targeted at the supracondylar femoral area in immature skeletons. Hemiepiphysiodesis might be a more feasible option in those cases as it provides the surgeon with the choice to remove the staples when necessary.

The coracoid base is a very rare location for tumors. It is difficult to diagnose and approach, but easy to dismiss. In this case, the tumor (eosinophilic granuloma of the scapula) was located at the base of the coracoid, and the posterior cortex was eroded by the tumor. Accessing this lesion through the deltopectoral approach with coracoid osteotomy without penetrating the supposed tumor extending posterior soft tissue will be discussed. This approach gives a wider and safer access to the surgeon than the posterior approach. This report presents a customized solution with the deltopectoral approach, and the chevron-type osteotomy to access the coracoid base and tension band wiring to fix the osteotomy side.

Background . The aim of the study was to evaluate whether or not there was any incompatibility between four-strand hamstring tendons taken from the same knee and the dimensions of the ACL and PCL. Methods . 15 fresh frozen cadaver hamstrings were prepared as four-strand grafts and measurements made of the ACL and PCL circumferences in the midsection were made in the narrowest part of the midsection. The cross-section areas and diameters were calculated with geometric calculations used to measure the cross-sectional area of cylinders. Accepting that the geometric insertions were elliptical, the length, width, and area were calculated for entry areas. Results . A significant relationship at 96.2% was determined between the ACL mid and the hamstring diameter. A significant relationship at 96.7% was determined between the ACL and the hamstring mid area. A significant relationship at 96.4% was determined between the PCL mid and the hamstring diameter. A significant relationship at 95.7% was determined between the PCL and the hamstring mid area. Conclusion . For the reconstruction of ACL and PCL, it was determined that there is less incompatibility between the four-strand hamstring tendons taken from the same knee and the dimensions of the midsection PCL compared to the ACL dimensions., Competing Interests: The authors declare that they have no competing interests.

We would like to highlight unusual sequelae of healed distal third diaphyseal tibia fracture that was treated conservatively 36 years ago, in which we incidentally detected peripheral CT angiography. The anterior tibial artery was enveloped three-quarterly by the healing callus of the bone (distal tibia).

The painful os peroneum syndrome is widely recognized. It is often the result of trauma. However degenerative changes between the os peroneum and the articular facet is much rarer and we could only find two other case reports in the literature. This report concerns a middle aged woman with chronic plantar-lateral foot pain and a limp secondary to degenerative changes between the os peroneum and its articular facet with cuboid. The aim of this study is to remind to orthopaedic surgeons about painful os peroneum syndrome and to highlight the rarity of our case. In our case the mid term result of the excision of the os peroneum with painful articulation appear good, providing symptomatic pain relief with little alteration in the function of the foot., (Copyright © 2014 European Foot and Ankle Society.

Inferior shoulder dislocation also referred to as luxatio erecta is an unusual and rare type of shoulder dislocation. Its incidence is about 0.5% among all shoulder dislocations. After an exhaustive search of all the available literature we were unable to find a swimming accident case that did not have other associated injuries and an uneventful reduction. The mechanism of the injury was mostly related to direct axial loading and indirect hyperabduction lever arm. We would like to emphasize the importance of this being a swimming accident, a type of accident that requires awareness of the possibility of dangerous asphyxia injuries caused by panic in the water (swimming pool, river, lake, sea, etc.). We described the nature of the injury and review the literature concerning the mechanism of the injury and associated neurovascular impairment at admission time. We also presented a supplemental video to contribute to the education of young residents and orthopedic surgeons.

Herein, we report clinical, radiological, and follow-up results of seven cases of extraordinary located osteochondromas and highlight the importance of rare and unusual properties of unusual locations of osteochondromas. Seven patients with extraordinary located osteochondromas were treated in our institution (Antalya Memorial Hospital) between the period of February 2009 and March 2014 were reported. The patients were classified according to the localization, symptomatology, and the presence of neurovascular involvement or organ compression. The results were discussed with the existing literature data. Five of our patients had unusual symptomatology. Surgical excision was performed on six of seven patients. One patient was followed with scheduled outpatient visits alone. Our clinical follow-up results were good to excellent. In our case series, one patient with clavicular involvement had impaired shoulder mechanic which resulted in painful shoulder, while another with pubic ramus involvement had obstructive urination symptoms and dysuria. One patient with scapular involvement had snapping scapula symptoms, while two patients with fibular head involvement had peroneal nerve compression and tibial nerve compression symptoms in each. One patient with ischial ramus involvement had sciatica, whereas another with first rib involvement had radiological evidences for subclavian artery compression due to osteochondroma without any symptom. Based our experience, the flat bones which are usually ossified by intramembranous type of ossification during the fetal period (including the scapula, ilium, pubic ramus, ischium ramus, ribs and clavicle) are much less commonly affected and often have unusual symptoms. The osteochondromas originating from the fibular head may seem innocent to an orthopedic surgeon. However, an orthopedic surgeon should be alert to tibiofibular synostosis and nerve compression in this patient population.

Our patient was a 76-year-old female who has been operated on 2 times in 8 years for pelvic chondrosarcoma. The patient came to our clinic with a large mass in left iliac region which extended into the paravertebral area. Physical examination and preoperative imagining studies revealed a mass at the left iliac area that infiltrated sciatic notch and extended from posterior iliac region towards the anterior side of iliac bone through the sciatic notch and an incisional hernia including descending colon. The mass was also penetrating the abdominal cavity through the hernia. Surgical intervention was planned. Since the tumor infiltrated the sciatic nerve, hemipelvectomy was indicated. Patient refused hemipelvectomy. Therefore, palliative debulking surgery was considered. We treated the case with marginal excision and abdominal wall reconstruction employing prolene and vicryl suture materials in order to prevent a postoperative visceral herniation and local invasion. At the latest follow-up appointment in 2 years, the patient still had no signs of tumor recurrence. This case showed us that an incisional hernia can serve as a pathway for the recurrence invasion of the chondrosarcoma.

We present a 25-year-old male case of osteochondroma originating from ischial ramus which causes sciatica. The pelvic involvement is rare. Iliac crest of the pelvis is often involved. Ischial ramus involvement is extremely rare. In this article, we presented a rare case of ischial ramus involvement that misleading the physician to L4-L5-S1 radiculopathy.

This report concerns an unusual cause of anterior ankle impingement. The case of a young male with Trevor's disease mimicking an anterior spur of the ankle that resulted in anterior impingement and treated with ankle arthroscopy is presented. The aim of this study is to explain the different diagnostic properties of Trevor's disease from a classic anterior spur. Level of evidence IV.

The concentrations of cadmium, cobalt, chromium, copper, iron, manganese, nickel, lead and zinc were determined by ICP-AES in muscles and livers of 12 fish species sampled from the Marmara, Aegean and Mediterranean seas of Turkey. Iron showed the highest levels in examined tissues of all fish species. Following Fe, Zn generally showed the second highest levels. Metal concentrations in edible parts of fish species were 0.02-0.37mgkg(-1) for cadmium, 0.04-0.41mgkg(-1) for cobalt, 0.04-1.75mgkg(-1) for chromium, 0.32-6.48 mgkg(-1) for copper, 7.46-40.1mgkg(-1) for iron, 0.10-0.99 mgkg(-1) for manganese, 0.02-3.97mgkg(-1) for nickel, 0.33-0.86mgkg(-1) for lead, 4.49-11.2mgkg(-1) for zinc, respectively. All metal concentrations in livers were higher than those in muscles. In some stations, cadmium and chromium concentrations in both muscles and livers, and lead levels in livers of the examined species were higher than permissible safety levels for human uses., (Copyright © 2007 Elsevier Ltd.

Transient osteoporosis of the hip is a rare disease of unknown etiology. It is usually seen in middle-aged men and women in the third trimester of pregnancy and is associated with hip pain. It typically runs a benign course with eventual resolution of symptoms. We report three patients who presented with unilateral hip pain that started in the third trimester of pregnancy. Diagnosis of transient osteoporosis of the hip was made with the help of clinical and radiologic studies. Treatment was comprised of pain control therapy with diclofenac sodium (100 mg/day) for three months, bed rest for a month followed by mobilization with a walking aid. The follow-up period was at least 24 months. Clinical improvement occurred in the third month in one patient, and at the end of six months in the remaining patients. Complete radiologic improvement was seen at the end of 12 months.
