Lipofilling (fat grafting) in the secondary prevention of ischial tuberosity and pelvic pressure ulcers.

Abstract

Retrospective study. Lipofilling was proposed to adult chronic spinal cord injury patients with history of ischial tuberosity pressure ulcers surgery, at risk of recurrence of pressure ulcers due to unsatisfactory adipose tissue thickness. Fondation Hopale, Berck, France. The three staged (Coleman) procedure for fat grafting consisted of water-jet assisted liposuction (Harvest-Jet), decantation, and reinjection of the autologous fat in three-dimensional plan. Ten consecutive patients (eight paraplegics and two tetraplegics) benefited from bilateral ischial lipofilling, with additional lipofilling of the sacrum (three patients) and the trochanters (two patients). All patients attended the seating clinic with pressure mapping before and after lipofilling for appropriate cushion prescription. Mean follow-up time was 16 months (4-24 months). Complications were limited to stage I (two patients) and stage II (one patient) pressure ulcers, due to negligence. Excellent results with minimal fat wasting (between 10% and 25%) underneath the ischial tuberosity were seen in eight patients, with significant improvement of adipose tissue thickness. Total fat waste was seen in two patients, one of whom following dramatic weight loss. Results were always good in the sacrum and trochanteric areas. Lipofilling allowed longer sitting times (three patients), improved skin quality (nine patients), improved quality of life (six patients), 'a better feeling of positioning in their wheelchair' (four patients), and decrease in pelvic pain (three patients). Pelvic lipofilling is safe, cost-effective, and can now be considered in the primary prevention of pelvic pressure ulcers in patients with insufficient adipose tissue.
