摘要
目的探讨关节镜辅助下采用双Endobutton带袢钢板内固定治疗后交叉韧带胫骨止点撕脱骨折的疗效。方法选择自2014-05—2016-04采用双Endobutton带袢钢板内固定治疗15例后交叉韧带胫骨止点撕脱骨折,关节镜监视下行骨折清创复位。比较术前、术后Lysholm评分及膝关节功能活动状态。结果 15例获得随访3~18个月,平均9.6个月。末次随访复查X线片显示后交叉韧带胫骨止点撕脱骨折均达到解剖复位或接近于解剖复位;2例出现Ⅰ度后抽屉试验阳性,其余抽屉试验结果均为阴性;术前Lysholm评分为(46.1±2.7)分,术后(94.2±3.6)分,术后Lysholm评分优于术前,差异有统计学意义(P<0.05)。术后膝关节活动度恢复正常者13例;有2例术后4~8周出现膝关节轻度屈曲受限者,活动度(0°~90°),给予非麻醉下手法松解患膝,活动度可改善至0°~120°。结论关节镜下采用双Endobutton带袢钢板复位并固定后交叉韧带胫骨止点撕脱骨折,具有创伤小、仿生物力学固定、固定可靠、骨折块大小不影响手术方案的优点,操作简单,康复快,值得推广应用。
Objective To investigate the effect of arthroscopic double Endobutton plate in the treatment of posterior cruciateligament（PCL） tibial avulsion fracture. Methods Fifteen cases of tibial avulsion fracture of PCL treated by arthroscopy fromMay 2014 to April 2016 were selected. Under arthroscopy fracture debridement and reduction were performed. Thepreoperative and postoperative Lysholm score and knee joint motion were compared. Results Fifteen cases were followed upfor 3-18 months with an average of 9.6 months. At the time of the last follow-up X-ray film showed that the fracture wasanatomically reduced or near anatomic reduction. Two patients had degree I of positive posterior drawer test,other patientshad negative drawer tests. Between preoperative （46.1±2.7） and postoperative Lysholm score （94.2±3.6）, the difference wasstatistically significant （P 〈0.05）. There were 13 patients with normal knee motion after operation, 2 patients with mild limitedknee flexion 4-8 weeks after operation, knee flexion 0-90 degree, and the motion of the knee joint recovered to 0-20 degreeafter manipulation release. Conclusion Arthroscopic double Endobutton plate in the treatment of PCL tibial avulsion fractureis minimally invasive, biomechanical, reliable fixation and the size of bone block does not affect the operation plan. Operationis simple, recovery is quick, it is worth popularization and application.
