OBJECTIVE The repair of soft tissue defect of heel by traditional operation did not restore the sensation of the heel. METHODS In order to solve this problem, the saphenous neurovascular skin flap reinnervated by end-to-side neuro-anastomosis was designed and 3 male patients with soft tissue defects of the heel were so treated. Grossgraft of saphenous neurovascular skin flap was employed for repairing the soft tissue defects of heel and the pedicle was divided at 21 days after operation. The end-to-side neuro-anastomosis was used to reinnervate not only the skim flap, but also the skin area of the medial malleolus, medial aspect of the foot and the big toe of the donor limb. RESULTS After follow-up of 6-12 months, the walking and weight bearing functions of the affected limbs were good, the contour of the grafted area was satisfactory, and the recovery of sensation of the skin flap, the medial malleolus, the medial aspect of the foot and the big toe was observed. CONCLUSION 1. Crossgraft of the saphenous skin flap was an effective method to repair the soft tissue defect of the heel; 2. End-to-side neuro-anastomosis could restore the sensation of the skin flap.
【Abstract】 Objective To evaluate the long-term effectiveness of composite grafts of acellular dermal matrix (ADM)and autologous spl it-thickness skin in repairing deep burn wounds. Methods Between June 2002 and December 2008, 30 patients (42 wound) were treated. There were 25 males and 5 females, aged 3-52 years with a median age of 31 years. Of them, 24 burned patients had 35 wounds, including 23 deep second degree and 12 third degree wounds with a mean disease duration of 24 days (range, 3-45 days); 6 patients with hyperplastic scar had 7 wounds with a mean disease duration of 16 days (range, 9-21 days). The wound locations were neck (2 wound), hand (4 wounds), forearm and elbow (8 wounds), shoulder (3 wounds), poples (6 wounds), laps (4 wounds), ankle and legs (15 wounds), and the area of wounds ranged from 10 cm × 10 cm to 30 cm × 20 cm. After thorough debridement, tangential excision, and scar excision, ADM and autologous spl it-thickness skin graft were used to repair the wounds by one-step method. Results After operation, composite skin graft survived completely in 39 wounds of 27 patients, with a survival rate of 92.9%; partial necrosis occurred in 3 wounds of 3 patients (7.1%), and healed after dressing change and secondary skin graft. The patients were followed up 30-34 months (mean, 32 months) postoperatively. The appearance of the composite grafts were smooth and soft with good elasticity and low pigmentation. The activity and function of limbs recovered well. No scar hyperplasia was observed at the donor sites. Conclusion It can achieve good outcomes in appearance and function to use ADM and autologous spl it-thickness skin graft for repairing deep burn wounds in functional regions.
