闭合复位经皮穿针内固定治疗Bennett骨折

Treatment of Bennett's fracture with closed reduction and percutaneous Kirschner wire fixation

目的:评价一种新型的经皮穿针内固定方法治疗Bennett骨折的疗效。方法:采用闭合复位经皮穿针内固定方法治疗Bennett骨折13例,其中男8例,女5例;年龄20～45岁(平均32岁);受伤至手术间2～7d,平均4.3d。术后拇指"人"字石膏固定30～41d(平均35d)。以关节面复位情况、疼痛症状及功能评价术后疗效。结果:所有病例均获随访,时间4～9个月(平均6.4个月),所有病例均达骨性愈合,关节面复位良好。仅有1例活动时有轻度疼痛。患者的握力有不同程度影响。结论:闭合复位经皮穿针内固定操作方法简单、固定确切、效价比高,特别适用于三角形骨块较小的Bennett骨折。

Objective ：To evaluate clinical effect of new method of percutaneous Kirschner wire fixation in treating Bennett＇s fracture. Methods ：Thirteen patients with Bennett＇s fracture were treated with close reduction and percutaneous Kirschner wire fixation. There were male 8 cases and female 5 cases with an average age of 32 years （range from 20 to 45 years）. The mean time from injury to operation was 4.3 days （range from 2 to 7 days）. External fixation with plaster slab was applied after operation with an average of 35 days （range from 30 to 41 days）. The reduction of articular surface, symptom of ache and function of thumb after operation were evaluated. Results：All the patients were followed up with an average of 6.4 months （range from 4 to 9 months）. All fractures united and the articular surfaces were reduced well. Only 1 case has mild pain when activity. The grasp force decreased in all patients. Conclusion： Close reduction and percutaneous Kirschner wire fixation has advantage such as simply operation, precisely fixation, high potency ratio. The method especially fits Bennett＇s fracture with small triangular fragment.
