Kaplan's lesion is a rare complex metacarpophalangeal joint dislocation. A 7-year-old female child presented with pain, swelling and inability to move her right index finger. Her mother gave a history of sustaining a fall injury on the same hand around 3 weeks back. Radiographs showed a complex dorsal metacarpophalangeal joint dislocation. As the injury was already 3 weeks old at presentation, a few attempts at closed reduction were tried, under anaesthesia, which was unsuccessful. So, the patient underwent open reduction through a dorsal approach. At a 1-year follow-up, the patient was pain-free and had regained full range of motion of the index finger metacarpophalangeal joint. The differential diagnosis of Kaplan's lesion should be considered when a child presents with finger dislocation.

卡普兰氏病变是一种罕见的复杂掌指关节脱位。一名 7 岁女性患儿因右手食指疼痛、肿胀和无法活动而就诊。她的母亲说大约 3 周前她的手曾受过跌倒伤。X 线片显示复杂的背侧掌指关节脱位。由于就诊时损伤已经过去 3 周，因此在麻醉下尝试了几次闭合复位，但均未成功。于是，患者接受了经背侧入路的切开复位。1 年随访时，患者无疼痛，食指掌指关节活动度完全恢复。当儿童出现手指脱位时，应考虑卡普兰氏病变的鉴别诊断。
