Free functional muscle transplantation of an anomalous femoral adductor with a very large muscle belly: a case report

J Brachial Plex Peripher Nerve Inj. 2013 Oct 28;8(1):11. doi: 10.1186/1749-7221-8-11.

Abstract

We report the case of a 34-year-old man with a total brachial plexus injury that was treated by free functional muscle transplantation to restore simultaneously elbow flexion and finger extension. The muscle had a very large muscle belly (12 cm width), which was considered anatomically to be a fusion of the gracilis and the adductor longus muscles. Although the muscle possessed two major vascular pedicles with almost equal diameters, only the proximal vascular pedicle was anastomosed to the recipient vessels during the transplantation surgery, resulting in partial necrosis of the muscle. Several authors have reported on the successful simultaneous transplantation of the gracilis and adductor longus muscles, because they are supplied generally by a single common vascular pedicle. However, the present study suggests that when a surgeon encounters an aberrant femoral adductor with a very large muscle belly that can be considered to be a fusion of these muscles, the surgeon should assess intraoperatively the vascularity of the muscle using Doppler sonography, indocyanine green fluorescence injection, or other techniques.
