钢丝张力带治疗Bennett骨折

目的探讨以钢丝张力带固定Bennett骨折的手术方法及临床疗效。方法对28例Bennett骨折患者行钢丝张力带内固定术，术后对第一腕掌关节功能、疼痛及拇指的捏力、握力进行评估。结果本组28例，全部得到随访，随访时间13-18个月，影像学显示均达到骨性愈合，愈合平均时间为5周。第一腕掌关节屈伸平均达到48°，拇指外展平均达到80°，捏力及握力平均达到7．3kg和41．0kg。结论采用钢丝张力带固定Bennett骨折．是一种有效的内固定手术方法。

Use of tension band wiring for the treatment of bennett fractures

Objective To report the use of tension band wiring technique for the treatment of Bennett fractures. Methods From May 2007 to July 2010, 28 Bennett fractures in 28 patients were treated by using tension band wiring. Outcome assessments included range of motion of the thumb and pinch and grip strength of the hand. Results Fracture healing was achieved in all patients at a average time of 5 weeks. Followed-up ranged from 13 to 18 months. The mean extension-flexion arc of the first carpometacarpal joint was 48~. The mean thumb abduction was 80~. The mean pinch and grip strength of the injured hands were 7.3 and 41.0 kg, respectively. Conclusion Tension band wiring is an useful and rehable technique, and presents another fixation option for the treatment of Bennett fractures.
