The limited incision harvest of the rectus femoris flap for complex groin wound management.

Abstract

Muscle flaps can be effective in the protocol of complex groin wound management, yet donor-site morbidity remains a continued concern. The purpose of this study was to present a minimally invasive approach to the harvest of the rectus femoris flap (RFF) for groin wound vascularized tissue coverage. A retrospective study examined all patients undergoing RFF coverage and reconstruction of a complex groin wound between July 1, 2010, and December 31, 2011. During the study period, the senior author (S.K.K.) performed all RFF harvests through a minimally invasive approach, whereas all other surgeons performed the RFF harvest through a standard approach. Patients who underwent a minimally invasive RFF approach were compared with those who underwent the standard incision. Forty-three patients underwent RFF coverage procedures, 11 of which were carried out using the minimally invasive technique. The patients in the minimally invasive cohort were older (P = 0.03) but had similar rates of medical comorbidities. Minimally invasive RFF harvests were more commonly performed in the planned, salvage setting (P = 0.03). No difference was found in the vascular surgery procedure type (P = 0.13), presence of exposed prosthetic graft material (0.2), or rate of culture-positive wound (P = 0.67). Importantly, no differences in operative time (184.4 [45.5] minutes vs 169.3 [31.7] minutes, P = 0.45) or postoperative complications were observed, with no graft losses or major limb-related morbidity in either group. The RFF continues to be a workhorse flap for complex groin wounds, most often in the salvage setting. This study demonstrates that a minimally invasive approach can be used for flap harvest with equivalent results to that of the standard longitudinal incision.
