title: [Reconstruction of phalangeal defect with free mesio-forearm flap based on perforator of ulnar artery].
abstract: OBJECTIVE
  To discuss the therapeutic effect and clinical experience of a new technique of digital reconstruction with the free mesio-forearm flap based on perforator of ulnar artery.
  
  
  METHODS
  We marked the line from the pisiformis to the condylus medialis humeri as the axis of the flap. We used Doppler to detect the site of the mesio-forearm ulnar perforator which is usually 9-10 cm proximal to the condylus medialis humeri as center of the flap. We designed the flap that contained perforator artery with its accompanying vein of the ulnar artery and a superficial vein around the center spot along the axis of ulnar artery. The wound at donor site was sutured directly. Neurorrhaphy was not conducted in any cases.
  
  
  RESULTS
  From June 2005 to June 2009, all 12 flaps survived with good quality and aesthetic contour. And no necrosis occurred. We conducted 6-36 months follow-up, and the result was satisfactory. The function of the fingers was reserved. Two-point discrimination differed from 6 cm to 12 cm.
  
  
  CONCLUSIONS
  The free ulnar perforator flap on mesio-forearm can repair digital defect with good therapeutic effect, leaving less morbidity at donor site.
