人工真皮复合自体刃厚皮片移植治疗烧伤后关节瘢痕挛缩

目的观察人工真皮复合自体刃厚皮片移植治疗烧伤后关节部位瘢痕挛缩的疗效。方法选择深度烧伤后期瘢痕严重增生挛缩造成关节畸形的患者40例，共46个关节部位。在全身麻醉下切除挛缩瘢痕，彻底松解，矫正关节畸形，先用人工真皮覆盖创面，后移植自体刃厚皮片。嘱患者早期行功能锻炼。术后随访6个月，对术后局部外形、弹性、硬度、关节功能等进行效果评价。结果所有患者利用人工真皮复合自体刃厚皮片移植后皮瓣全部成活，外形、质地及关节功能明显改善。结论人工真皮复合自体刃厚皮片移植术可用于治疗深度烧伤患者关节部位的瘢痕挛缩。

Treatment of the cicatricial joint contracture after burn with artificial derma combined with autologous razor thin graft

Objective To observe the effect of artificial derma combined with autologous razor thin graft for treating the cicatrieial joint contracture after burn. Methods A total of 40 patients （46 joints） with joint malformation caused by severe cicatricial hyperplasia and contracture after deep burn were selected in this stud- y. Under general anaesthesia, contractural scar was removed and released completely to correct the joint malfor- mation by covering the wound with artificial dermis and transplanting the autologous razor thin graft. Following up was performed after operation for 6 months and the local contour, flexibility, hardness and joint function of recipient site were observed and evaluated. Results All flaps survived and the contour, texture and joint func- tion were improved obviously. Conclusion Artificial dermis combined with autologous razor thin graft is a new and good way to repair the eicatricial joint contracture after burn.
