An elite collegiate boxer developed extensor tendon subluxation in the small finger of his dominant right hand. He was thought to have a radial sagittal band disruption and was allowed to complete his season with custom padding. Surgical exploration revealed intact sagittal bands with divergent dislocation of the two extensor tendons to the small finger with underlying capsular rupture. These lesions were repaired and he successfully returned to boxing. Soft tissue injuries to the dorsal MCP joint may involve the collateral ligaments, the sagittal bands, the extensor tendons, or the joint capsule. Symptoms usually involve persistent pain, swelling, and tendon subluxation or dislocation. Accurate recognition and treatment is crucial as nonoperative treatment is generally unsuccessful and surgical reconstruction is required for optimal return to function.
一名精英大学拳击手的优势右手小指出现了伸肌腱半脱位。他被认为存在桡侧矢状带断裂，并被允许使用定制衬垫完成赛季。手术探查发现矢状带完整，但两条伸肌腱向小指发散性脱位，伴有深层关节囊破裂。对这些损伤进行了修复，他成功重返拳击赛场。掌指关节背侧的软组织损伤可能累及侧副韧带、矢状带、伸肌腱或关节囊。症状通常包括持续疼痛、肿胀以及肌腱半脱位或脱位。准确的诊断和治疗至关重要，因为非手术治疗通常不成功，需要进行手术重建才能实现功能的最佳恢复。
