The mallet finger is a frequently encountered fingertip injury that leads to extensor lag of the distal phalanx. Classification systems stratify these injuries as ranging from soft-tissue disruption of the extensor mechanism alone to those that have articular involvement and volar subluxation. The management of mallet finger injuries varies based on injury pattern and surgeon preference. These treatment options include splinting regimens, closed reduction and percutaneous pinning, and open reduction and internal fixation. Although the final goal of treatment is to establish a congruent joint, the efficacy of each treatment modality has been shown to vary.
锤状指是一种常见的指尖损伤，导致远节指骨伸肌滞后。分类系统将这些损伤分为单纯伸肌机制的软组织撕裂，以及伴有关节受累和掌侧半脱位的损伤。锤状指损伤的治疗因损伤类型和外科医生的偏好而异。这些治疗选择包括夹板固定、闭合复位和经皮钢针固定以及切开复位和内固定。尽管治疗的最终目标是建立一个吻合的关节，但每种治疗方式的疗效已被证明有所不同。
