肩锁钩板治疗不稳定性锁骨外侧段骨折的临床研究

目的：比较肩锁钩板和传统克氏针内固定治疗不稳定性锁骨外侧段骨折的疗效。方法：54例不稳定性锁骨外侧段骨折的患者接受了手术治疗，内固定分别是锁骨钩板或克氏针，根据国外的锁骨外侧段骨折肩部功能评价标准进行6－12个月的术后随访，随访结果运用统计学方法进行分析处理，结果：克氏针内固定组的手术优良率为77．3％，并发症发生率为27．3％，骨折愈合率为81．8％；锁骨钩板内固定组的手术优良率为100％，并发症发生率为3．1％，骨折愈合率100％。两组数据统计学差异有显著性，结论：在不稳定性锁骨外侧段骨折的手术治疗中，锁骨钩板较传统克氏针内固定有较高的手术优良率和骨折愈合率，且并发症的发生率较低，因此，它是一种疗效满意的内固定方法。

Study on Treating Unstable Fractures of Distal with Hook-Plate

Objective: To evaluate the effects of the two kinds of fixation on treatment of unstable distal clavicular fractures. Methods: Fifty four patients with unstable fractures of distal clavicle were fixed with Kirschner Wire(K-wire) or hook plate. Those patients were followed up and their function of the shoulder was assessed by L'Insalata's method 6-12 months after operation. The results of two groups were analysed statistically. Results: The excellent or better results were 77. 3% and 100% espectively and the rate of complications were 27. 3% and 3. 1% respectively in the K-Wire fixation and hook plate groups. The differences between two groups were significant. Conclusion: The group of fixation with hook plate is better than K-Wire fixation group in function restoration of shoulder and low rate of complications, it is therefore worth while to treat unstable fracture of distal clavicle in clinical practice.
