Tension Band Fixation for Type II Fracture of the Distal Clavicle

PURPOSE: To evaluate the efficacy of the tension band wire fixation for type II distal clavicle fractures. MATERIALS AND METHODS: Twenty one patients with type II distal clavicle fractures were evaluated, who were operated with tension band fixation technique with sparing AC joint, from May 2000 to December 2003, and could be followed-up for more than 1 year after operation. Average age at injury is 40.7 years old (14~73). 13 cases were males and 8 were females. And 16 cases were classified as type IIa and 5 cases as type IIb. Judgement of union was based on plain x-ray and clinical finding and postoperative assessment was evaluated on ASES and Constant scoring system. RESULTS: Outcomes in all patients showed more than good, average ASES score was 96.1 (88~98) and Constant score was 93.1 (82~100). Radiologic union was achieved at 11.7 (6~16) weeks postoperatively. One patient suffered from non union, and there was no other significant complications such as K-wire migrations, breakage, infection, and AC joint arthritis. CONCLUSION: Tension band fixation technique for type II distal clavicle fracture seems to be a useful and effective method, which is relatively simple and provides rigid fixation without violating the AC joint.
