急性后交叉韧带下止点撕脱骨折患者的双排锚钉桥式缝合治疗12例报告

Efficacy of the treatment for acute posterior cruciate ligament avulsion fracture using double-row suture anchor insertion combined with suture-bridge and improved Duncan loop:report of 12 cases

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.
