Abstract

Background: Recurrent pressure sores and unstable scars over the bony prominences of the greater trochanter and ischium are a troublesome sequela of spinal injury. A reliable reconstruction is needed for patients with ‘dual-defect’ pressure sores in these locations. We modified the pedicled anterolateral thigh (ALT) flap to fit the reconstructive requirements of ‘dual-defect’ pressure sores.
Methods: Eleven consecutive patients with concurrent pressure sores (> grade III) or unstable scar in one of the ‘dual-defect’ areas and an active pressure sore in the other were identified from the Victorian state tertiary referral centre for spinal injuries. We describe the technique and clinical experience of pedicled ALT flaps for reconstruction of ‘dual-defect’ pressure sores in this patient cohort. Preoperative status and minor and major postoperative complications were recorded.
Results: Eleven consecutive pedicled myocutaneous ALT flaps were performed for reconstruction of ‘dual-defect’ pressure sores. Several key variations in the anatomical landmarks and the intra-operative flap raise technique that are integral to the use of the ALT flap for this application are described herein. The average dimensions of the cutaneous pressure sore defects were 6 x 4.9 cm (greater trochanter) and 8.2 x 6.7 cm (ischial). The average dimensions of the cutaneous paddle of the flaps raised were 27.3 x 8.4 cm. Two postoperative complications necessitated return to theatre but no incidences of flap loss were recorded.
Conclusions: The modified pedicled myocutaneous ALT provides a robust reconstructive solution for resurfacing ‘dual-defect’ pressure sores in spinal patients. Further recommendations for future technical adaptations are made.
