目的探讨形状记忆合金环抱器治疗锁骨骨折的疗效及适应证。方法采用形状记忆合金环抱器治疗锁骨骨折36例,其中锁骨中段骨折33例,中外1/3骨折3例。结果35例获平均随访16个月(8～20个月),X线片示术后平均2.8个月(2～4个月)骨折临床愈合,根据韩平良等的疗效标准,优22例,良11例,可2例,优良率94.3%。结论形状记忆合金环抱器治疗锁骨骨折具有创伤小,固定可靠,操作安全等优点,适用于锁骨中段、内侧段骨折,骨折位于锁骨外1/3弯曲处时应慎用。

Clinical evaluation of the shape memory alloy embracing fixator for treatment of clavicular fractures

Objective To study the effect and indication of the shape memory alloy(SMA)embracing fixator for treatment of clavicular fracture.Methods Thirty-six cases with clavicular fr acture were treated with SMA embracing fixator,of which 33we re middle third fracture and 3were between middle and lateral fracture.Results Thirty-five cases were followed up f or an average of 16months(from 8to 20months)and the average clinical healing was 2.8months(between 2and 4months).The results were evaluated accordi ng to Han Pingliang' s criteria and showed that 22cases wa s excellent,and 11cases was good.The excellent and good rate was 94.3percent.Conclusion The internal fixation with SMA embra cing fixator is less traumatic,stab le,safly effective to treat clavicular fracture.It is recommendable for treatment of clavicu lar fracture located in the middle an d proximal.The SMA embracing fixator must be pru dently used when the fracture is in th e curvature of clavicle.
