The ANK device: a new approach in the treatment of the fractures of the lateral malleolus associated with the rupture of the syndesmosis.

The ANK device was developed for the treatment of fractures of the lateral malleolus occurring with rupture of the syndesmosis. While it provides the anatomic reduction of the fracture and the syndesmosis, it allows the physiologic movements of the fibula. It is not used for comminuted fractures of the lateral malleolus and in cases where fibular medullary canal is narrow. We included forty-nine patients who had the ANK device applied and at least 2 years follow-up. The mean follow-up was 41 months (range 24-124). The fractures were evaluated according to the Lauge-Hansen classification; 25 cases were evaluated as supination-external rotation, 11 cases were pronation-abduction, and 13 cases were pronation-external rotation type fractures. There were also 46 fractures of the medial malleolus and three ruptures of the deltoid ligament. Twenty-nine (59,2%) patients were evaluated as excellent, 12 (24,5%) as good, 5 (10.2%) as fair and 3 (6.1%) as poor. Arthrosis was observed in 3 (6.1%) of the patients.

Multiple diffuse fibrosarcoma of bone.

Multiple diffuse fibrosarcoma of bone is a very rare condition, with only 3 cases reported. Its presentation is like that of a multiple myeloma or a metastatic tumor, with multiple osteolytic lesions, and its extent is limited to the bones. Disseminated involvement of the vertebrae was detected in a 26-year-old man, suggesting a metastatic tumor; however, no primary organ or soft-tissue mass was identified. The histopathologic findings of the biopsy material were consistent with fibrosarcoma. Despite treatment, the patient died within 15 months.

Compression neuropathy of the peroneal nerve caused by a ganglion.

Peroneal nerve injury usually results from fracture of the fibula neck or direct pressure from an ill-fitting plaster cast. Clinically, these patients present with "drop foot." Compression neuropathy caused by a ganglion is rarely encountered. This report concerns the clinical and radiologic evaluation of a 57-year-old man admitted to our clinic with left drop foot. A mass compressing the peroneal nerve at the level of the fibula neck was excised totally and diagnosed as a ganglion.

Avascular necrosis of the femoral head in childhood: the results of treatment with articulated distraction method.

The treatment of avascular necrosis of the femoral head in children is still being debated. We performed articulated distraction in 11 children with avascular necrosis of the femoral head between March 1994 and February 1997. The reasons for avascular necrosis were: Perthes disease in eight patients, fracture of the femoral neck in two, and complication arising because of treatment of developmental hip dysplasia in one. Mean age was 7.9 years. Fixator duration time was 3.5 months and mean follow-up was 32 months. At follow-up, the femoral head was spherical and congruent in four patients, aspherical and congruent in five, and aspherical and incongruent in two according to Stulberg's criteria. The aim of the articulated distraction method is to neutralize muscle and weight-bearing forces, to prevent stress fractures of subchondral immature bone, to encourage synovial circulation, and to promote creeping substitution.

Fine needle aspiration of malignant bone lesions.

OBJECTIVE: To determine the role of fine needle aspiration (FNA) cytology in the early diagnosis of malignant bone lesions. STUDY DESIGN: Thirty-eight bone lesions that were considered malignant clinically and radiographically were evaluated by FNA. The results were compared with the histopathology of the subsequent open biopsies. RESULTS: An accuracy rate of 89.5% was achieved by FNA. Eighty-four percent of the cases were consistent with the clinical and radiographic findings. Chondrosarcoma gave the greatest diagnostic difficulty in the differential diagnosis with other chondroid tumors. Giant cell tumor cases also produced some difficulty when the cytology was hemorrhagic and low in cellularity, displaying features of other benign bone lesions containing giant cells. Ewing's sarcoma and multiple myeloma could be identified when interpreted with their coexistent clinical findings. The metastatic carcinoma cases were also easy to define, forming another group with a high rate of accuracy. CONCLUSION: FNA plays a valuable role in the initial diagnosis of malignant bone lesions. Cytologic assessment with the clinical and radiologic findings, together with the experience of the cytopathologist, can yield almost the same diagnostic accuracy in the majority of the lesions.
