Banking a fillet flap to aid in reconstruction following a hindquarter amputation

A hindquarter amputation and hemipelvectomy for recurrent malignancy presents a reconstructive challenge to the plastic surgeon. Tumour resection leaves a considerable defect, with exposure of bone, neurovascular structures, pelvic and abdominal organs. A free lower leg fillet flap is a recognised method of providing soft tissue coverage, but ischaemic time is often lengthy as described in the literature. We present a unique method of providing soft tissue coverage using a free lower leg fillet flap, and minimising ischaemic time by banking the flap on the ulnar artery during the hindquarter amputation and tumour resection.Level of Evidence: Level V, therapeutic study.
