记忆合金聚髌器在治疗髌骨骨折中的应用

Application of the Nickel - Titanium patella concentrator in surgical treatment of patellar fracture

目的:探讨记忆合金聚髌器治疗髌骨骨折的应用价值。方法:采用记忆合金聚髌器治疗髌骨骨折53例,其中横断骨折31例,粉粹性骨折19例,纵行骨折3例。结果:术后随访0.5-5年,骨折全部愈合,关节功能恢复良好。按照改良的Bostman髌骨骨折临床疗效评估标准:优40例,良12例,可1例,优良率为98%。结论:记忆合金聚髌器治疗髌骨骨折,具有固定牢靠,术后可早期活动,并发症少等优点,值得临床推广。

Objective：To discuss the application value of the Nickel - Titanium patella concentrator （NT - PC） in surgical treatment of patellar fracture.Methods：A retrospective analysis was made on clinical data of 53 cases of patel- lar fracture treated with the NT-PC in this hospital. Results ：Re - examination of radiography at 12 weeks after surgery showed bone union was achieved in all the cases, with a smooth patell of emoral articular surface. The patella was pres erred completely in all the comminuted fracture cases. According to the Bostman＇s criteria, excellent and good outcomeswere achieved in 40 and 12 cases, respectively, the rate of excellent or good results being 98.1%. The NT - PC was removed at 6 months-5 years postoperatively without complications. Conclusions ：Application of NT - PC in the treatment of patellar fracture can preserve the comminuted patella completely, facilitate the reduction and fixation of the patellofemoralarticular surface, and make early postoperative motions available. It is worthy of being recommended.
