A 66-year-old woman presented 10 days after dropping a knife onto her right foot. She was diagnosed with a complete, retracted extensor hallucis longus (EHL) rupture. A recommendation for acute repair was made, but she opted against surgery and was treated with observation and supportive care. At 1 year, the patient regained active extension of her big toe and had no gait disturbances or functional impairment.
There is no literature on the natural history of a retracted EHL rupture. Surgery is typically advised to prevent symptomatic drop toe and theoretical subsequent deformity. This case illustrates the potential for restoration of extension of the hallux without surgical repair.
一名66岁女性在右脚被刀割伤10天后前来就诊。她被诊断为拇长伸肌（EHL）完全性回缩断裂。建议进行急诊修复，但她选择不做手术，而是接受观察和支持治疗。1年后，患者大脚趾恢复了主动背伸，没有步态障碍或功能受损。
目前尚无关于回缩性EHL断裂自然病程的文献报道。通常建议手术治疗以预防症状性足下垂及理论上随后出现的畸形。本病例说明了拇趾背伸无需手术修复即可恢复的可能性。
