摘要
[目的]探讨胫骨内侧高位楔形截骨治疗膝内翻畸形的疗效。[方法]1998年7月～2007年10月,采用胫骨内侧张开式高位楔形截骨结合植骨钢板内固定术治疗膝内翻畸形共49例72个膝关节。患者术前、术后8周、术后1.5年行患肢全长X线片检查,测量胫股角、胫股内侧关节间距大小。按HSS膝关节功能评定标准评定术前、术后膝关节功能。[结果]72膝术后随访18～128个月,平均58个月;胫股角术前187.5°±5.3°,术后172.6°±3.6°,膝关节功能由(47.2±17.6)分增至(83.2±15.3)分,胫股内侧关节间距由(2.4±1.2)mm增至(4.3±1.2)mm。植骨均愈合满意,无膝内翻复发。术后疼痛缓解及行走功能改善显著。术中出现关节内骨折3例,无神经血管损伤。术后皮肤感染切口延迟愈合2例。[结论]胫骨内侧高位楔形截骨结合植骨钢板内固定术,可作为治疗膝内翻畸形的有效方法之一。
[Objective]To discuss the efficacy of medial wedged proximal tibial osteotomy for treating genu varus deformity.[Methods]From July 1998 to October 2007,49 patients with genu varus deformity were treated by medial wedged proximal tibial osteotomy combined with internal fixation.Full-length anterior-posterior radiographs were taken preoperatively at 8 weeks and 1.5 years postoperatively.The parameters including the femorotibial angle and the medial joint space were measured on the radiographs.The pre-and postoperative function of knee were evaluated according to the HSS score system of the knee.[Results]All the 49 patients were followed up from 18 to 128 months.The mean postoperative femorotibial angle decreaced from 187.5°±5.3° to 172.6°±3.6°.The mean postoperative HSS score significantly improved from 83.2±15.3 to 47.2±17.6 points after 1.5 years of operation.The medial joint space increased from（2.4±1.2） mm to（4.3±1.2） mm.There were complications in 5 cases： 3 cases of intra-articular...更多 fracture during operation and 2 of postoperative superficial wound infections.There were no delayed union,no recurrence of varus deformity,and no blood vessels or nerves injury in all cases.The pain relieved and walking function improved significantly postoperativly.[Conclusion]Medial wedged proximal tibial osteotomy combined with internal fixation is an effect approach to treat genu varus deformity.
