上胫腓关节迟发性脱位致腓总神经麻痹（附3例报告）

作者报告了３例胫腓骨骨折致上胫腓关节迟发性脱位引起的腓总神经麻痹．结合文献分析了发病机理、临床特征和治疗方法．认为腓骨完整，或骨折已穿针内固定的胫骨不稳定骨折或胫骨缺损是迟发性上胫腓关节脱位的前提；肌肉纤维化、癜痕挛缩、过早负重等可致小腿纵向挤压力增加，是脱位的主要原因．腓总神经麻痹与其局部被固定有关。膝外侧疼痛和明显的骨性突出是常见脱位症状和体征．主张切除腓骨小头，酌情松解腓总神经．

Tibia Fibula Upper Joint Delayed Dislocation Lead to Nervus Peroneus Communis Paralysis-A Report or 3 Cases

The authors report 3 cases about nervus peroneus communis paralysis occoured from tibia fibula fracture. With reference,We analysed the pathogenesis.clinical feature and treatment. We think that unstable fracture of defect of tibia with totoal fibula (or after the internal immobilization) is the prereguisite of tibia fibula upper joint delayed dislocation. But the main reason o f abarticulation are muscular fibrosis,cicatricial contracture, early weight training and so on,leading to the augmentation of the longitudinal crush power to the leg. Nervus peroneus communis paralysis is related to the local fixation of the nervus peroneus communis branching. The common symptom and syndrome of dislocation are the pain of the lateral knee and the clear hong hernia.Resection of fibula capitulumor and lysis of nervus peroneus communis should be used.
