A 39-year-old woman sustained a forced dorsiflexion injury to the left great toe while pivoting to the right during tennis activity. Posteromedial ankle pain was reproduced with active plantarflexion and passive dorsiflexion of the great toe and, to a smaller extent, the lesser toes. Symptoms persisted for 9 months despite nonoperative treatment. Magnetic resonance imaging 5 months after injury revealed evidence of fluid surrounding the flexor hallucis longus (FHL) tendon. Operative findings 9 months after injury included scar tissue and tenosynovitis of the FHL and flexor digitorum longus tendon sheaths, with impingement of distal FHL muscle fibers and a longitudinal split tear (partial rupture) of the FHL tendon. Tenolysis, tenosynovectomy, excision of the distal muscle fibers, and repair of the partial tendon rupture were performed, resulting in resolution of symptoms. Partial rupture of the FHL tendon as a single-impact injury, or in activity other than ballet, has not been documented previously.
一名39岁女性在网球活动中向右转身时，左拇趾遭受强制背屈损伤。主动跖屈和拇趾及程度较轻的其他脚趾被动背屈时，会再现踝关节后内侧疼痛。尽管进行了非手术治疗，症状仍持续了9个月。受伤5个月后的磁共振成像显示拇长屈肌腱（FHL）周围有积液迹象。受伤9个月后的手术发现包括FHL和趾长屈肌腱腱鞘的瘢痕组织和腱鞘炎，远端FHL肌纤维受到撞击，以及FHL肌腱的纵向裂伤（部分断裂）。进行了肌腱松解术、腱鞘切除术、远端肌纤维切除术和部分肌腱断裂修复术，症状得以缓解。FHL肌腱作为单次撞击损伤或在芭蕾舞以外的活动中出现部分断裂，此前尚无文献记载。
