Use of free serratus anterior muscle slips for the reconstruction of dorsal-side defects of the hand resulting from hot press injury

Abstract

Mutilation of the hand as a result of hot press injury, the common characteristics of which are extensive soft tissue and extensor tendon loss, metacarpal and phalangeal necrosis, exposition of multiple joints, and infection, presents a serious challenge to the hand surgeon. Free transfer of the inferior three slips of the serratus anterior muscle is a useful surgical option for the reconstruction of dorsal-side defects in the hand. The versatility of the three separate slips, which are easily divisible for contouring, enables individual reconstruction of the different digits. Long vascular pedicle, low donor-site morbidity, and durability are other advantages. Four male patients with hot press injury of the dorsal side of the hand were treated with free transfer of serratus anterior muscle slips and split-thickness skin grafts. Follow-up period ranged between 5 and 12 years. Late functional and cosmetic results are presented.
