目的探讨膝关节镜下空心钉内复位固定治疗青少年前交叉韧带(ACL)下止点撕脱骨折的手术方法和疗效。方法对17例青少年前交叉韧带(ACL)胫骨止点撕脱骨折均采用关节镜下前外侧入路单或双枚空心钉内固定。结果 17例均获随访3~12个月X线片示骨折复位满意,均骨性愈合,功能满意末次随访时Lysholm评分92~100分,平均96.7分。结论膝关节镜下单或双枚空心钉内固定前交叉韧带胫骨止点撕脱骨折技术具有微创便捷固定可靠的优点,值得推广。
Objective To investigate the surgical methods and curative effects of hollow nail fixation under knee arthroscopy in the treatment of avulsion fractures of adolescent anterior cruciate ligament (ACL). Methods Seventeen cases of avulsion fractures of the anterior cruciate ligament (ACL) tibia were treated with arthroscopic anterolateral approach with single or double cannulated screw fixation. Results All the 17 cases were followed up for 3 to 12 months. The X-ray showed that the fractures were satisfied and the bony union was satisfied. The Lysholm scores at the final follow-up ranged from 92 to 100 with an average of 96.7 points. Conclusions The technique of single or double hollow nail fixation for anterior cruciate ligament tibial avulsion fracture under knee arthroscopy has the advantage of minimally invasive and convenient fixation and reliability and is worthy of popularization.
