Résumé
The aim of the current study is to investigate the first and second lumbrical nerves as potential fibers donors to the deep motor branch of the ulnar nerve to avoid intrinsic atrophy in high ulnar nerve injuries. Sixteen fresh frozen cadaveric hands were dissected, the radial lumbrical nerves accessed, and a coaptation, either in reverse end-to-side or in double end-to-side through a bridge nerve graft, was created to the deep motor branch of ulnar nerve. Semithin sections were taken from samples of donor and recipient nerves for qualitative (nerve architecture) and quantitative studies (fiber count and donor/recipient ratio). The first lumbrical showed a robust trunk and a superior axon density (9,126.50 ± 2,923.41 axons/mm A transfer from the first lumbrical nerve to the deep motor branch of the ulnar nerve in palm is suitable to avoid intrinsic atrophy.
