摘要目的:探讨削薄股前外侧穿支皮瓣（ALTP）修复手部外伤术后瘢痕挛缩畸形切除后软组织缺损的方法和疗效。方法:自2015年3月至2019年8月,应用削薄ALTP修复手部外伤术后挛缩瘢痕12例。先行手部挛缩瘢痕组织彻底切除,恢复手部正常的骨性结构及力线,手部缺损创面为5.0 cm×6.0 cm~8.0 cm×10.0 cm；遗留创面于大腿外侧设计ALTP修复,皮瓣I期显微修薄,皮瓣均不携带阔筋膜。供区直接拉拢缝合。术后门诊复查、微信随访,观察创面愈合及皮瓣外观、质地、感觉、供区瘢痕及患手活动功能恢复情况,指导其进行康复训练。结果:术后12例皮瓣全部成活,术后2例因穿支电凝处出血,血肿卡压静脉发生静脉危象,经探查后皮瓣成活。本组术后均随访,其中门诊复查6例,微信视频随访4例,电话咨询2例；随访3~20个月,平均11个月。术后皮瓣不臃肿,质软,无色素沉着,外形美观；皮瓣供区仅遗留1条线形瘢痕。患手的握、捏、对掌、对指等功能得到大部分恢复。按照中华医学会手外科学会上肢部分功能评定试用标准,TAM评定：优7例,良4例,可1例。结论:削薄ALTP修复手部外伤术后瘢痕挛缩畸形,可携带不同组织进行立体修复,术后皮瓣外形美观,供区可直接闭合,减少供区损伤,是修复手部挛缩畸形的一种有效方法。

abstractsObjective:To explore the method and effect of free thining anterolateral thigh perforator flap (ALTP) in repairing soft tissue defect of scar contracture deformity after hand trauma.Methods:From March, 2015 to August, 2019, 12 patients who suffered scar contracture after hand trauma were repaired with thin ALTP. First, completely resected the scar contracture tissue from the hands and restored the normal bone structure and force line of the hand. The area of hand wound defects were 5.0 cm×6.0 cm-8.0 cm×10.0 cm. The wound was repaired by free ALTP, and the flap was micro-thinned for the first time. The flaps did not carry broad fascia, and the donor sites were directly sutured. The wound healing, the flap appearance, texture, sensation, scarring of the donor area, and functional recovery of the affected hand were observed regularly after surgery. The patients were followed-up by outpatient review and WeChat.Results:All the flaps survived well after the operation. Two cases suffered crisis because hematoma entraps vein cause by bleeding from perforator branch. After surgical exploration, the flaps survived successfully. All 12 flaps were followed-up successfully, including 6 cases reviewed in outpatient clinic, 4 cases followed by WeChat video and 2 cases by telephone consultation. The follow-up time was 3-20 months, with an average of 11 months. The flaps were not bloated, soft, non-pigmented, and beautiful in appearance. Only linear scars remained in the donor sites. The gripp function, palm function, thumb opposition function and finger function of the affected hand were largely restored. According to the TAM method of Upper Limb Function Evaluation of the Chinese Medical Association: 7 cases were excellent, 4 cases were good, and 1 case was fair.Conclusion:The thinning ALTP can be used to repair the scar contracture deformity after hand trauma. It can carry different tissues for 3-dimensional repair. After operation, the flap has a beautiful appearance, the donor site can be closed directly, and the damage of donor site can be reduced. It is an effective method to repair the hand contracture deformity.
