PURPOSE To evaluate the clinical and radiological results of the treatment of mid-shaft clavicular nonunions using intramedullary fixation with threaded Steinmann pin and bone grafting.
MATERIAL AND METHODS: In 16 patients treated with intramedullary fixation of threaded Steinmann pin and autogenous iliac bone grafting for the mid-shaft clavicular nonunions, 10 patients with follow-up over 1 year were investigated. All patients (10 clavicle fractures) underwent conservative treatment initially. The average age of patients was 56 years old (range, 18~70 years old). Eight cases were atrophic nonunions, two hypertrophic. A clinical assessment was evaluated postoperatively after 5 months according to the evaluation method of Kona et al. RESULTS According to the evaluation method of Kona et al, four cases achieved excellent results, five cases good, and one case achieved a fair result. The average period until bony union was 9 weeks (range, 7~12.5 weeks) without infection, pin migration or breakage. One case showed skin irritation by lateral margin of Steinmann pin, which was subsided by pin removal after bony union. CONCLUSION We obtained satisfactory results and have concluded that intramedullary fixation with threaded Steinmann pin and bone grafting could appropriately treat nonunions of the mid-clavicular fracture occurred after conservative treatment, because it minimizes soft tissue injury, gets relatively stable fixation and early ROM, predicts early bone union, facilitates pin removal under local anesthesia.
PURPOSE To investigate the usefulness of closing wedge osteotomy with threaded steinmann pin and wiring for the treatment of cubitus varus deformity after elbow fracture during childhood. MATERIALS AND METHODS From February 1994 to February 2002. We performed closing wedge osteotomy with threaded steinmann pin and wiring in 16 elbows with cubitus varus deformity. There are 11 men and 5 women. Mean age was 21.6 years and mean follow-up was 19.2 months. Mean deformed carrying angle was varus 21.7 degree. Mean period from initial injury to treatment was 16.5 years. RESULTS Mean angle that was corrected by above operation methods was valgus 12 degree. Average periods of immobilization was 27.8 days. One tardy ulnar nerve syndrome before surgery was solved at 8 weeks after operation. 2 cases with superficial infection was treated easily. 14 cases of all were estimated as good with Oppenheim's criteria. CONCLUSION Closing wedge osteotomy with threaded steinmann pin and wiring makes early range of motion exercise being possible as rigid fixation. The supracondylar closing wedge osteotomy with threaded Steinmann pin and wiring is thought to be the useful method.
