螺钉与经皮克氏针治疗Buechler2区Bennett骨折的2年随访

Two-year follow-up of screws versus percutaneous K-wire for the treatment of Bennett fractures in Buechler zone 2

背景:治疗Bennett骨折方法颇多,对于较为多发的Buechler2区Bennett骨折目前尚无统一的治疗方案及评价标准。目的:对比切开复位螺钉内固定及经皮克氏针内固定对Buechler2区Bennett骨折固定后的功能恢复情况。方法:将Buechler2区Bennett骨折患者随机分为螺钉治疗组和克氏针治疗组,螺钉治疗组施行切开复位螺钉内固定,克氏针组施行闭合复位经皮交叉克氏针内固定。采用上肢功能评分评价其功能恢复情况。结果与结论:固定后、随访1年及随访2年,螺钉组上肢功能评分均低于克氏针组(P<0.05)。证实,短期内螺钉对于Buechler2区Bennett骨折的功能恢复优于克氏针。

BACKGROUND： There are a lot of methods for the treatment of Bennett fractures; however, there is no uniform therapeutic regimen and evaluation criterion for the more prone Buechler zone 2 Bennett fractures. OBJECTIVE： To compare the function recovery of open reduction screw fixation and percutaneous pinning for the treatment of Buechler zone 2 Bennett fractures. METHODS： Patients with Buechler zone 2 Bennett fractures were randomly divided into the screw group and the K-wire group; the patients in the screw group were treated by open reduction screw fixation and the patients in the K-wire group were purposed by close reduction percutaneous fixation. The disabilities of the arm, shoulder and hand score were used to evaluate the function recovery. RESULTS AND CONCLUSION： The disabilities of the arm, shoulder and hand score of the screw group were lower than those of the K-wire group after fixation, 1-year follow-up and 2-year follow-up （P 〈 0.05）. The functional recovery of open reduction screw fixation is better than percutaneous K-wire fixation for Buechler zone 2 Bennett fractures.
