This anatomical study was carried out in order to discover the etiology of partial necrosis of the peroneus longus and brevis muscles after fibular osteocutaneous flap harvest. The vascular supply to the lateral compartment peroneal muscles was investigated in 10 fresh cadaveric lower limbs. The peroneal muscles are supplied by two principal sources arteries, the anterior tibial artery (ATA) and the peroneal artery (PA). The ATA is the dominant artery and supplies the proximal and middle thirds of these muscles. The PA is considered to be a supplementary vascular source and supplies the distal thirds of these muscles. After harvesting the PA in a fibular flap, regions of the peroneal muscles preoperatively vascularized by its branches become supplied through the anastomotic "choke" vessels between the ATA and the PA. Primary closure of the cutaneous defect increases the possibility of developing a pseudo-compartment syndrome with necrosis of the more precariously vascularized portions of the peroneal muscles. This complication is difficult to diagnosis early and the reason why we advocate that direct skin closure following composite harvest must be avoided. Moreover, conservation of the inferior and superior lateral branches of the ATA is imperative in order to preserve the peroneal muscles vascularization. |
