关节镜辅助内固定治疗胫骨髁间嵴骨折11例临床体会

Clinical experience of 11 cases of avulsion fracture of the tibial eminence to approach the anterior cruciate ligament insersion under arthroscope

目的探讨关节镜辅助下治疗胫骨髁间嵴前交叉韧带止点撕脱骨折的手术方式。方法对11例患者根据髁间嵴骨折不同的形态类型,分别选择丝线、克氏针、可吸收螺钉、空心螺钉固定前交叉韧带止点撕脱骨块,术后指导功能锻炼。结果所有病例随访3～36个月,术后3～4个月骨折部位均愈合,采用Lysholm膝关节评价疗效,平均得分92.6分。结论关节镜辅助下根据髁间嵴撕脱骨折的不同类型选择不同内固定方式,可得到准确的复位、良好的骨折愈合及满意的膝关节功能恢复。

Objective To discuss the operation approach which treats avulsion fracture of the tibial eminence to approach the anterior cruciate ligament insersion under arthroscope.Methods 11 cases respectively chose silk suture,Kirschner wire,absorbed screw,hollow screw to fix avulsion bone on the anterior cruciate ligament insersion according to different types of the tibial eminence fracture,and postoperative functional exercise were directed.Results All cases were followed up from 3 to 36 months,all cases healed after 3 to 4 months on fracture part.According to the Lysholm knee joint score which was used to evaluate the curative effect,the average score was 92.6.Conclusion Through different internal fixation under arthroscope according to different avulsion fracture of the tibial eminence,we can abtain precise reduction,good union of fracture and satisfactory functional recovery of knee joint.
