Closed traumatic flexor injuries of the hand involving the pulley mechanism are a relatively common injury seen in rock climbers but are very rare in nonclimbers, including bowlers. The injury was first described in 1990. Since then, several studies have shed more light on the diagnostic and therapeutic considerations. Early diagnosis of pulley injuries is crucial since delayed diagnosis can lead to limited range of motion, particularly at the proximal interphalangeal joint. Flexion contractures at the proximal interphalangeal joint have also been cited in the literature. We discuss a case of pulley injury in a bowler and briefly review the anatomy of the pulley architecture, mechanism of injury, imaging manifestations, and clinical management of this injury.
涉及滑车机制的手部闭合性创伤性屈肌损伤在攀岩者中较为常见，但在包括保龄球运动员在内的非攀岩者中极为罕见。该损伤于1990年首次被描述。自那时以来，多项研究对其诊断和治疗考量有了更深入的了解。滑车损伤的早期诊断至关重要，因为延迟诊断会导致活动范围受限，尤其是近端指间关节。近端指间关节的屈曲挛缩在文献中也有提及。我们讨论一例保龄球运动员的滑车损伤病例，并简要回顾滑车结构的解剖、损伤机制、影像学表现及该损伤的临床处理。
