镍钛聚髌器内固定治疗粉碎性髌骨骨折

Effect of nitinol patellar concentrator on comminuted patellar fracture

目的探讨镍钛聚髌器内固定治疗粉碎性髌骨骨折的疗效。方法对54例粉碎性髌骨骨折采用镍钛聚髌器内固定治疗,并与克氏针张力带法治疗的54例进行回顾性比较和分析。结果术后随访6个月￣3年,克氏针张力带法治疗粉碎性骨折优良率50.0%,镍钛聚髌器法治疗粉碎性骨折优良率90.7%,两者比较差异有显著性(P<0.05)。结论镍钛聚髌器可作为粉碎性髌骨骨折的首选方法。

[Objective] To investigate the effect of Nitinol Patellar Concentrator on comminuted patellar fracture. [Methods] We retrospectively reviewed the treatment of comminuted patellar fracture with Nitinol Patellar Concentrator in 54 patients, comparing with other 54 patients treated by Kirsehner-wire internal fixation. [Results] The follow-up time was 6-36 months. Of 108 cases, the excellent rate of treatment on comminuted pateUar fracture was 50% by Kirschner-wire internal fixation, and 90.7% by Nitinol Patellar Coneentrator. The effect of Nitinol Patellar Concentrator was better than that of Kirschner-wire internal fixation （P 〈0.05）. [Conclusion] The Nitinol Patellar Concentrator can be the best therapy on eomminuted patellar fraeture.
