TiNi形状记忆合金与钛合金重建钢板内固定治疗锁骨骨折疗效比较

目的:比较形状记忆合金与重建钢板治疗锁骨骨折的疗效差异及特点.方法:采用形状记忆合金治疗锁骨中段骨折25例,重建钢板治疗锁骨中段骨折32例.结果:记忆合金出现2例松脱,重建钢板1例部分翘起,经及时处理后均达临床愈合,两组优良率均达到90%以上.结论:两者均能达良好的治疗效果,形状记忆合金具有操作简便的特点,但对于外1/3处以及粉碎性骨折要谨慎使用,应用重建钢板相比较而言更具广泛性和可靠.

Clavicular Fracture Treated by Re-setting Steel-plate Internal Fixation with TiNi Shape-memory Alloy and Titanium Alloy

Objective:Compare the curative effects and features between treating clavicular fracture with re-setting steel plate and shape-memory alloy.Methods:Treat 25 cases of mid-clavicular fracture with shape-memory alloy,32 with re-setting steel plate.Result:Loose and falling happened in 2 cases treated with memory alloy,partly protruding in 1 case with steel plate,they were all clinically cured after timely treatment,the good effective rates of both groups were above 90%.Conclusion:Two methods have good curative effect;the shape-memory alloy is simple and easy for operation,which should be carefully applied for the fracture on lateral 1/3 point,and the re-setting steel plate is more popular and reliable compared with re-setting steel plate shape-memory allooy.
