Sensate anterolateral thigh perforator flap for ischiatic sores reconstruction in meningomyelocele patients

Recidivating pressure sores are a frequent complication in meningomyelocele patients because of their limitation in motility and their scarce ability to monitor the pressure applied on insensate areas while seated. We report the utilization of the sensate pedicled anterolateral thigh perforator flap for reconstruction of ischiatic sores in meningomyelocele patients. Between May 2011 and September 2013, five patients underwent transfer of a sensate pedicled anterolateral thigh flap, by an intermuscular passageway through the upper thigh, to reach the ischial defect. Flap was properly harvested from the thigh after assessment of the lateral cutaneous femoral nerve sensitive area with the Pressure-Specified Sensory Device. In all cases the flap reached the ischial defect harmlessly, healing was uneventful with no immediate nor late complications. Each patient showed persistence of sensitivity at the reconstructed area and no recurrent ischiatic sore was observed at mean follow-up of 26.4 months. The sensate pedicled anterolateral thigh flap is a valuable solution for coverage of recurrent ischial sores in meningomyelocele patients, in which pressure consciousness is fundamental. The intermuscular passageway allows to reduce the distance between flap's vascular pedicle origin and the ischial defect, hence to use the more reliable skin from the middle third of the anterolateral thigh.
