目的 探讨双排锚钉桥式缝合及改良Duncan环治疗急性后交叉韧带撕脱骨折的安全性和有效性.方法 2012年1月至2015年2月,采用双排锚钉植入结合桥式缝合及改良Duncan环治疗急性后交叉韧带撕脱骨折12例.所有病例均行膝关节后方小切口,使用双排锚钉,采用桥式缝合及改良Duncan环固定骨折块.所有病例在术前、术后随访均采用Lysholm膝关节评分评估其疗效.结果 12例获得平均12.6个月随访.Lysholm评分,术前:(42.17±0.93)分,末次随访:(90.35±1.14)分,差异有统计学意义(P<0.05).结论 双排锚钉结合桥式缝合及改良Duncan环治疗急性后交叉韧带下止点撕脱骨折安全、有效.“,”Objective To explore the clinical outcomes of the treatment for acute posterior cruciate ligament avulsion fracture using double-row suture anchor insertion combined with suture-bridge and improved Duncan loop. Methods From January 2012 to February 2015, 12 patients with acute posterior cruciate ligament avulsion fracture were treated by using double-row suture anchor insertion combined with suture bridge and improved Duncan loop. Small incision surgery was performed on all patients on the posterior side of knee and double-row suture anchor technique was used. Suture-bridge and modified Duncan loop were used for fracture fixation. Clinical evaluation adopted Lysholm score system pre-operation and post-operation. Results Twelve cases received an average follow-up of 12.6 months. The Lysholm score was ( 42.17 ± 0.93 ) pre-operation and ( 90.35 ± 1.14 ) post-operation. The differences were statistically significant ( P < 0.05 ). Conclusions Double-row suture anchor insertion combined with suture-bridge and improved Duncan loop is a safe and effective method for acute posterior cruciate ligament avulsion fracture.
