关节镜下采用Rigidfix和Intrafix系统 固定重建后交叉韧带

Arthroscopic reconstruction of posterior cruciate ligament with Rigidfix cross pins and Intrafix screw

摘要:

目的 评价关节镜下采用Rigidfix可吸收横穿钉和Intrafix膨胀挤压螺钉系统固定重建后交叉韧带的疗效。方法 2008年6月～2011年6月，对17例后交叉韧带损伤的患者，关节镜下重建时采用Rigidfix固定移植肌腱股骨侧，Intrafix固定移植肌腱胫骨侧，对患者手术前后行后抽屉试验及Lysholm评分。结果 随访时间22～46个月（平均33.7个月），所有患者膝关节不稳感均消失，关节活动度均达120°以上，Lysholm评分从术前（53.62±4.28）分增加到术后（88.5±3.4）分，手术前后比较，差异具有显著性（P <0.05）。结论 关节镜下采用Rigidfix可吸收横穿钉和Intrafix膨胀挤压螺钉固定系统重建后交叉韧带，固定可靠，临床效果满意。

Abstract:

【Objective】 To evaluate the clinical effects of arthroscopic reconstruction of posterior cruciate ligament with Rigidfix cross pins and Intrafix screw. 【Methods】 From June 2008 to June 2011, 17 cases of PCL injuries were treated. Rigidfix cross pins were used for femoral side fixation, Intrafix screw was used for tibial side fixation. Patients were evaluated by the posterior drawer test and Lysholm scores before operation and followed up. 【Results】 All cases had been followed up for 22 to 46 months(average 33.7 months), after operation, all joints unstable were disappear, the flexion degree was more than 120 in all cases. Lysholm scores raised from (53.62±4.28) before operation to (88.5±3.4) after operation. Each index was significant between before and after operation(P <0.05). 【Conclusion】 The method of Rigidfix cross pins and Intrafix screw under arthroscopy for PCL reconstruction is reliable, which can lead to good clinical results.
