Mallet finger injuries are a common presentation in the emergency department. These injuries result from a forced flexion at the distal interphalangeal joint (DIPJ) that causes extensor tendon disruption, and possibly bone avulsion, at the base of the distal phalanx. This article describes the anatomy, mechanisms, classification and assessment of mallet finger injury. It reviews different types of splints used in the conservative management of closed tendinous mallet finger injury and discusses the latest evidence regarding immobilisation methods and treatment duration. Maintaining the DIPJ in extension during treatment is essential, so the article stresses the importance of patient adherence to treatment.
锤状指损伤在急诊科较为常见。这些损伤是由于远节指间关节（DIPJ）的被迫弯曲引起的，导致伸肌腱在远节指骨底部断裂，甚至可能发生撕脱。本文描述了锤状指损伤的解剖结构、机制、分类和评估。它回顾了用于闭合性肌腱锤状指损伤保守治疗的不同类型夹板，并讨论了关于固定方法和治疗持续时间的最新证据。在治疗过程中保持 DIPJ 伸展至关重要，因此本文强调了患者对治疗的依从性的重要性。
