PURPOSE: To investigate the utility of cannulated screw in operative treatment of the clavicular fracture. MATERIALS AND METHODS: From December 1999 to December 2002, 23 patients with clavicular fracture were underwent operative treatment with cannulated screw. Their mean age was 40.1 years and the sites of fracture were 16 cases in middle 1/3, 7 cases in lateral 1/3, 12 cases were comminnuted fracture. The clinical and radiological results were evaluated. RESULTS: According to the Kang's criteria, the clinical results were excellent in 18 cases (78.3%), good in 4 cases (17.4%) and fair in 1 case. Radiologically, all cases showed bone union and the average time was 7.9 weeks. Complications such as infection, nonunion, metal failure has not been observed. CONCLUSION: Open reduction and internal fixation with cannulated screw could be considered as an alternative method of treatment in clavicular fracture, when indications for primary surgical treatment are presents.
