Spontaneous rupture of the extensor pollicis longus is a rare injury. Distal radius fractures and rheumatisms are the principal causes, but there is an increase in cases related to some professional or sports activities. We report a case of a semi-professional bodybuilder who presented with a full loss of interphalangeal thumb extension and retropulsion following trivial trauma of the left wrist. Ultrasound confirmed the diagnosis of spontaneous rupture of extensor pollicis longus, and MRI revealed a very rare and aggressive anatomical variant of Lister's tubercle. The patient underwent a transfer of the extensor indicis propius, which is the most popular technique used for hyperextension and retropulsion restitution. Aggressive anatomical forms of Lister's tubercle can explain the frequent occurrence of spontaneous rupture of extensor pollicis longus in patients who practice sports or professions with a repetitive movement of the wrist.
拇长伸肌自发性断裂是一种罕见的损伤。桡骨远端骨折和风湿病是主要病因，但与某些职业或体育活动相关的病例有所增加。我们报告一例半职业健美运动员，其在左手腕轻微创伤后出现拇指指间关节完全伸直丧失和拇指后推。超声确诊为拇长伸肌自发性断裂，磁共振成像显示了一种非常罕见且侵袭性的李斯特结节解剖变异。患者接受了示指固有伸肌转移术，这是用于恢复过伸和后推的最常用技术。李斯特结节的侵袭性解剖形式可以解释在从事手腕反复运动的体育或职业的患者中拇长伸肌自发性断裂频繁发生的原因。
