McBride手术治疗外翻疗效分析

目的总结McBride手术治疗外翻术后5年以上长期随访结果,并分析其疗效。方法自1985年1月～1995年12月,对行McBride矫形术的外翻患者进行随访,共随访50例(90足)。随访时间为5年～10年2个月,平均7年1个月。对畸形矫正程度、局部症状及足趾功能改善情况进行比较和分析,同时在术前、术后对部分患者进行足底负重点变化观察。结果第一跖趾角大小与第一、二跖间角大小有显著的相关性,手术前后相关系数分别为0.84和0.71。两者均与外翻程度有关;手术后足部症状改善、畸形基本矫正者共64足,手术优良率为71.1%。并发症主要有趾及前足疼痛、局部麻木、外翻复发、内翻、仰趾畸形等,部分行再次手术。结论McBride手术能有效地减小已经增大的第一跖趾角;外翻矫正后,第一、二跖间角也会相应缩小。McBride矫形术通过足部软组织力量平衡,能有效地改善患者足部症状、改善足部功能、矫正外翻畸型。对轻、中度及50岁以下较年轻外翻患者是一个较好的、可靠的手术方式。并发症的发生与足部先天性畸形、外翻程度较重及手术中过多的副损伤有关。

Result of McBride operation for treatment of hallux valgus

Objective To investigate the result of McBride operation for treatment of hallux valgus with more than 5 years follow-up. Methods There were totally fifity patients who underwent McBride operation in this study. The follow-up period varied from 5 years to 10 years and 2 months (average 7 years and 1 month). The symptoms and deformity before and after operation were compared statisticly. Results The angle between first phalanx and metatarsal is strongly correlated with the angle between first and second metatarsal.The coefficience of pre- and post-operation is 0.84 and 0.71 respectively.There were 64 feet whose symptoms were eliminated and the deformity were corrected basically. The effective rate was 71.1% according to the assessment criteria discribed by doctor ZHU Lihua. The common complications were pain residue, local numbness, hallux valgus recurrence, hallux varus and claw toes. The measurment showed the angle between first phalanx and metatarsal significantly decreased after operation and the angle between first and second metatarsal also decreased following the hallux valgus correction. Conclusion McBride operation is a good and reliable method to treat young patients with mild to moderate hallux valgus. Complications are related to congenital foot deformity, severe valgus deformity and normal structure injuries during the operation.
