摘要
目的探讨锚钉内固定治疗后交叉韧带(PCL)胫骨止点撕脱性骨折的临床疗效。方法对32例膝关节PCL胫骨止点撕脱骨折患者,采用膝关节后内侧倒"L"形入路切开复位,以锚钉内固定治疗,术后给予石膏托固定膝关节屈曲30°约4周,拆除石膏外固定后适当行膝关节伸屈功能锻炼。结果 30例获得随访,时间7～30个月,平均(13±5.2)个月。术后2～4个月均获骨性愈合,平均为(3±0.6)个月。手术6个月后依据Lysholm等膝关节评分系统评估膝关节功能,评定优26例,良3例,可1例,优良率96.7%。结论膝后内侧"L"形入路应用锚钉内固定治疗PCL胫骨止点撕脱骨折是安全有效、内固定可靠的,可在早期有效地重建膝关节的稳定性,恢复膝关节功能。
Objective To investigate the clinical efficacy of the treatment for tibial avulsion fracture of the posterior cruciate ligament （PCL） with open reduction and anchor screw internal fixation. Methods 32 patients of tibial avulsion fracture of the posterior cruciate ligament were treated with open reduction and anchor screw internal fixation through inverted L-shaped posterior-medial approach. All the patients were given postoperative plaster immobilization of knee at 30° flexion for about four weeks. The patients were allowed to appropriate functional exercise of knee flexion and extension after removal of the plaster. Results 30 patients were followed up for seven to 30 months with an average of （13±5.2 ） months. The bony union was achieved in all the patients after operation in two to four months, （3±0. 6） months in average. According to Lysholm knee score system, six months after surgery, 26 cases were excellent, three cases were good and one case was fair. The excellent rate was 96.7%. Conclusions Inverted L-shaped posterior-medial approach and anchor screw internal fixation is a safe, effective method for tibial avulsion fracture of PCL. Reliable internal fixation may be effective in the early reconstruction of the knee stability and restoring knee function.
