A Retrospective Look at Integrating a Novel Regenerative Medicine Approach in Plastic Limb Reconstruction

Abstract

Full-thickness wounds that have rendered patients candidates for amputation may require techniques that may include a combinatorial approach above traditional standard of care. The purpose of this retrospective study was to evaluate the effectiveness of an innovative approach whereby several therapies were combined to avoid amputation. Patients with full-thickness wounds who were previously recommended for amputation and were treated with the combinatorial approach of muscle flap reconstruction and concentrated bone marrow aspirate, platelet-rich plasma, INTEGRA Wound matrix, vacuum-assisted closure, and split-thickness skin grafts were assessed retrospectively. The mean age of the patients identified was 48 years (range, 34–66 years). The average size of the defects was 19.6 cm2. All defects were successfully covered with medial hemisoleus, lateral hemisoleus, or peroneus brevis muscle flaps combined with split-thickness skin grafts, concentrated bone marrow aspirate, and platelet-rich plasma. All flaps healed with an average time to fixator removal of 8.3 weeks; there was 1 above-knee amputation that occurred approximately after successful wound closing and fixator removal. The combinatorial approach described here including several regenerative medicine tools is an effective means of lower limb reconstruction to avoid amputation.
