An irreducible closed dorsal dislocation of the distal interphalangeal (DIP) joint of the finger is a rare injury, often caused by factors such as the interposition of the volar plate, entrapment of the flexor digitorum profundus (FDP) tendon behind the head of the middle phalanx, or the buttonholing of the middle phalanx head through the volar plate or flexor tendon. This case report presents a rare instance of FDP avulsion combined with dorsal dislocation of the DIP joint in a 42-year-old male who sustained trauma to his right middle finger during a workplace accident. Clinical examination and imaging confirmed FDP avulsion along with dorsal dislocation of the DIP joint. Urgent surgical intervention was performed, successfully reducing and repairing the FDP tendon and stabilizing the DIP joint. Subsequent follow-up showed satisfactory functional outcomes. This case highlights the importance of prompt diagnosis and appropriate surgical management in treating complex finger injuries.
手指远侧指间关节(DIP)不可复位的闭合性背侧脱位是一种罕见的损伤,通常由掌板嵌入、指深屈肌腱(FDP)在中节指骨头后方卡压、或中节指骨头经掌板或屈肌腱穿出等因素引起。本病例报告展示了一名42岁男性在工作事故中右手食指受伤,出现罕见的FDP撕脱合并DIP关节背侧脱位的情况。临床检查和影像学检查证实了FDP撕脱以及DIP关节背侧脱位。紧急进行了手术干预,成功复位并修复了FDP肌腱,稳定了DIP关节。随后的随访显示功能结果令人满意。本病例强调了在治疗复杂手指损伤时及时诊断和适当手术管理的重要性。
