Free fat autotransplantation for the cosmetic treatment of first web space atrophy.

The results of free fat autotransplantation for the correction of first web space atrophy were reviewed for 25 patients who sustained war injuries resulting in ulnar nerve palsies. In anticipation of partial graft resorption, a 30% overcorrection of the first web space deformity was performed compared with the normal hand. Average follow-up was 5 years. All patients were satisfied with their cosmetic results. Whereas 21 patients (84%) demonstrated less bulk when compared to their normal side, 4 (16%) retained slight overcorrection of the web space. After 1 year of follow-up, there was no further evidence of graft resorption. There were no long-term complications. We conclude that free fat autotransplantation for the cosmetic correction of atrophy of the first web space is a safe and effective procedure. Although graft resorption was encountered, overcorrection provided patients with dramatic cosmetic improvement.
