title: [Repair of deep wound on thumb using island flap from dorsoulnar side of thumb].
abstract: OBJECTIVE
  To study the effect of island flap from dorsoulnar side of thumb in repairing deep wound on thumb.
  
  
  METHODS
  Twenty-two patients with deep wound on thumb were hospitalized from May 2007 to December 2013. The wounds ranged from 2.0 cm x 1.5 cm to 4.0 cm x 2.5 cm in area. Island flap of dorsoulnar thumb was used to repair these defects, with flap area ranging from 2.1 cm x 1.6 cm to 4.1 cm x 2.6 cm. All the donor sites were closed by transplantation of full-thickness skin from upper medial arm.
  
  
  RESULTS
  All flaps survived with good blood supply. All deep wounds of thumb were closed. Skin grafts of donor sites all survived. Patients were followed up for 6 to 12 months. The texture, color, and shape of all flaps were satisfactory, and functions of injured thumbs recovered well.
  
  
  CONCLUSIONS
  Transplantation of island flap from dorsoulnar side of thumb can be performed easily with high survival rate and satisfactory configuration, and it is suitable for repairing deep wound of thumb.
