ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of island flap from dorsoulnar side of thumb in repairing deep wound on thumb.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
