骨折後伸拇長肌攣縮為少見之情況，其可能造成拇趾變形及活動受限。我們報告一例25 歲女性有脛骨及腓骨中段骨折後伸拇長肌攣縮，病人以Z 延長術治療成功。此罕見病例強調此攣縮可能發生在腓骨中段骨折，且是由肌肉起點結痂造成的。

Contracture of the extensor hallucis longus (EHL) after fractures is an uncommon condition. It causes deformity and limitation of the big toe. We report a case of 25-yearold woman had contracture of EHL after tibial and fibular midshaft fractures. The patient was successfully managed with Z-lengthening of the EHL tendon. This report highlights the rarity of the present case, which was possibly caused by fibular midshaft fracture and induced scarring of muscular origin.
