To investigate the characteristics of blood supply of popliteal fossa middle artery pedicled flaps and the feasibility of reconstruction of postburn popliteal fossa contractures using the flaps in children.
Between January 2008 and October 2010, 6 cases of postburn popliteal fossa contractures were recontructed using popliteal fossa middle artery pedicled flaps. Of them, 2 were boys and 4 were girls, aged from 2 years and 2 months to 10 years. All burns were caused by hot water. The wound ranged from 5 cm x 4 cm to 10 cm x 8 cm after scar relaxation. The size of the flap ranged from 6 cm x 4 cm to 11 cm x 9 cm. Donor sites were covered with split-thickness skin graft in 5 cases, and sutured directly in 1 case.
All the flaps and the skingraft survived; no vascular crisis or flap necrosis occurred. All incisions at donors and wounds healed by first intention. All patients were followed up 12-24 months. The color, texture, and appearance of the flaps were good. Hyperplastic scar was found at incision of popliteal fossa in 1 case at 6 months after operation; the range of motion (ROM) of the knee joint was 0-175 degrees, and no obvious change was observed at 15 months after operation. The others had no functional disturbance of the knee joints or claudication; the ROM of the knee joint was 0-180 degrees.
The popliteal fossa middle artery pedicled flap has reliable blood supply, simple operative procedure, and good results in reconstruction of popliteal fossa contracture.
探讨腘窝中间动脉蒂皮瓣的血供特点及该皮瓣用于小儿烧伤后腘窝瘢痕挛缩畸形修复的可行性。
2008年1月至2010年10月，采用腘窝中间动脉蒂皮瓣修复6例小儿烧伤后腘窝瘢痕挛缩畸形。其中男2例，女4例，年龄2岁2个月至10岁。致伤原因均为热水烫伤。瘢痕松解后创面大小为5 cm×4 cm至10 cm×8 cm。皮瓣大小为6 cm×4 cm至11 cm×9 cm。5例供区采用中厚皮片移植覆盖，1例直接缝合。
所有皮瓣及植皮均成活，未发生血管危象及皮瓣坏死。供区及受区切口均一期愈合。所有患者随访12～24个月，皮瓣色泽、质地及外形良好。术后6个月时，1例患者腘窝处切口有增生性瘢痕；膝关节活动度（ROM）为0～175°，术后15个月时无明显变化。其余患者膝关节无功能障碍及跛行，膝关节ROM为0～180°。
腘窝中间动脉蒂皮瓣血供可靠，手术操作简单，修复腘窝瘢痕挛缩畸形效果良好。
