目的探讨关节镜下利用单个锚钉固定治疗急性期前交叉韧带(ACL)止点撕脱骨折的手术效果。方法 5例急性期ACL止点撕脱骨折(Meyers and MckeeverⅢ型)患者,采用硬腰联合麻醉或单侧肢体神经阻滞麻醉,膝关节镜前内、前外侧及髌韧带正中入路,...目的探讨关节镜下利用单个锚钉固定治疗急性期前交叉韧带(ACL)止点撕脱骨折的手术效果。方法 5例急性期ACL止点撕脱骨折(Meyers and MckeeverⅢ型)患者,采用硬腰联合麻醉或单侧肢体神经阻滞麻醉,膝关节镜前内、前外侧及髌韧带正中入路,刨刀清理骨折端,在胫骨撕脱面骨床的后缘处打入直径5.0 mm带双缝线锚钉1枚,将缝线环绕撕脱的ACL骨块建立胫骨隧道,将缝线引出胫骨表面后打结收紧固定。观察预后效果。结果 5例患者术后随访时间5~12个月,中位随访时间9.6个月。ACL撕脱骨折均达到接近解剖复位上的愈合,中位愈合时间3.8个月。Lysholm评分结果优4例,良1例。恢复过程中,均未发生骨折块移位、锚钉缝线松脱、关节感染、锚钉异物反应等。结论关节镜下利用单个带线锚钉固定治疗急性期ACL止点撕脱骨折具有操作相对简单、骨块固定牢靠、创伤小、经济可行的优点,术后配合膝关节支具保护及口服消炎止痛药,能获得骨折愈合,并恢复膝关节正常功能,值得临床推广。展开更多
