目的:回顾总结热损伤后手部皮肤瘢痕挛缩的特点及矫形治疗。方法:自2014年1月至2019年6月我们共收治手部皮肤热损伤后指掌侧瘢痕挛缩畸形患者21例(24指)。所有患者掌指关节或指间关节屈曲畸形，患指无法完全伸直，关节总活动度为(152.71±17.41)°。根据手部瘢痕挛缩畸形程度以及皮片(瓣)供区情况，采用瘢痕切除松解、“Z”字改形或瘢痕切除后植皮、皮瓣移植修复，术后进行系统康复治疗。结果:术后21例患者均获得随访，时间为3～24个月，平均8个月，皮片、皮瓣均成活，受累关节得到完全或基本矫正。矫正患指时无需松解神经血管束，其中1例机器热压伤病例合并关节附属结构挛缩。术后关节总活动度为(227.83±28.09)°。术后各患指指端指腹痛温觉、两点分辨觉与术前无明显差异，亦无血运障碍，基本恢复患手形态及功能。结论:明确患指挛缩及受损程度，术前评估时可不必重点考虑指血管神经束挛缩和关节退化问题，与屈曲挛缩角度、范围无明显相关，患指屈曲挛缩矫正后无感觉及血运障碍。“,”Objective:To summary the feature and experience of orthodontic treatment in scar contracture malformation of hand after thermal injury.Methods:From January 2014 to June 2019, 21 cases (24 fingers) of scar contracture malformation of hand after thermal injury were treated. All the patients had flexion deformity of metacarpophalangeal joint or interphalangeal joint, and the affected fingers could not be extended completely. The total active motion of joint was (152.71±17.41)°. According to the degree of hand scar contracture malformation and the condition of skin (flap) of the donor site, the scar removal and release, “Z” shape modification or skin grafting and flap transplantation after the scar removal were performed. The systematic rehabilitation treatment were carried out after operation.Results:All the 21 patients were follow-up for 3 to 24 months with an average of 8 months. The skin and flap survived and the affected joint was completely or basically corrected. There is no need to release the neurovascular bundle in the correction of the affected fingers, and one case of mechanical thermal injury combined with the contracture of the joint accessory structure. The total active motion of joint was (227.83±28.09)° after operation. There was no significant difference in the pain and temperature perception and two-point discrimination of the fingertip and volar finger before and after the operation, and there was no blood circulation disorder. The shape and function of the hands were basically restored.Conclusion:It is necessary to determine the extent of the contractures and injuries of the affected finger. It is not necessary to focus on the neurovascular bundle contracture of the fingers and the degeneration of the joints during the preoperative evaluation, which is not related to angle and range of flexion contracture. There is no sensory and blood circulation disturbance after correction of flexion contracture of the affected finger.
