改良AO张力带与记忆合金聚髌器治疗髌骨骨折比较(附58例报告)

A comparison between improved AO-tension-band method and memory alloy patelllar concentrator method for the treatment of patellar fracture:Reports of 58 cases

目的 :探讨改良AO张力带与记忆合金聚髌器治疗髌骨骨折的最佳适应症。方法 :采用改良AO张力带法治疗 45例 ,记忆合金聚髌器治疗 13例。比较两种方法治疗各型髌骨骨折的疗效及各自的优缺点。结果 :观察 5 6例 ,其中最短随访 5个月 ,最长 6年。改良AO张力带固定 45例 ,优 39例 ,良 6例 ,可 2例。记忆合金聚髌器固定 13例 ,优 10例 ,良 3例。AO张力带法与记忆合金聚髌器疗效无显著差异。结论 :对于横行或相对大块的粉碎性骨折 ,AO张力带法应视为有效、可靠的选择 ;多平面、严重粉碎性髌骨骨折 。

Objective:To study the optimum indications of improved AO-tension-band method and Nickel-Titanium patellar concentrator(NT-PC) for the treatment of patellar fracture.Method:45 cases were treated with AO-tension-band and 13 cases were treated with NT-PC.The advantages and disadvantages of the two methods in treating various types of patellar fracture were compared.Results:All of 58 patients were followed-up for 5 months to 6 years.In 45 cases treated with improved AO-tension-band method:the result of the treatment was evaluated as excellent in 39 cases,good in 6 cases,fair in 2 cases.In 13 cases treated with NT-PC:excellent in 10 cases,good in 3 cases.'AO'is no more fine than NT-PC(P>0 05).Conclusion:Tension-band method is applicable for transverse fracture or comminuted fracture.NT-PC is the best selection for all of patellar fractures,especially for several comminuted fracture.
