title: [RECONSTRUCTION OF AVULSED INJURIES OF HEEL WITH A SENSORY PREFABRICATED FLAP].
abstract: OBJECTIVE
  To investigate the effectiveness of using a sensory prefabricated flap to repair the heel avulsion injury.
  
  
  METHODS
  Between August 2012 and August 2013, 6 cases of heel avulsion injury were treated. There were 4 males and 2 females, aged 16-54 years (mean, 29 years). The causes were crush injury in 4 cases and wheel twist injury in 2 cases. The injury to admission time was 2-6 hours (mean, 4 hours). The size of skin avulsion ranged from 5 cmx3 cm to 15 cmx8 cm. Avulsion skin had no replanted condition. At one stage operation, the avulsed heel skin soft tissue was made the full thickness skin graft which was fostered on the anterolateral thigh with lateral circumflex femoral artery perforator, and the lateral femoral cutaneous nerve was put beneath the skin to prefabricate the prefabricated flap; at two stage operation, the prefabricated skin flap pedicled with lateral circumflex femoral artery was used to repair the wound, and the lateral femoral nerve was anastomosed with the calcaneal nerve to reconstruct the feeling.
  
  
  RESULTS
  Six prefabricated flaps all survived, and re-plantation flaps survived after operation. The wounds healed by first intention at donor site and recipient site. The patients were followed up 1-2 years (mean, 1.5 years). The flaps had satisfactory appearance and soft texture. At 1 year after operation, the sensation of the flaps was S3, with two-point discrimination of 22-27 mm (mean, 24.3 mm). According to ZHANG Ming's evaluation standards, the results were excellent in 5 cases, and good in 1 case. The patients could walk normally or with weight-bearing; only linear scar formed at the donor site.
  
  
  CONCLUSIONS
  For patients with heel soft tissue avulsion injury without replantation qualification, a sensory prefabricated flap by the avulsed heel skin soft tissue can transplanted to repair the heel defect. Satisfactory effectiveness can be obtained in heel appearance and function recovery.
