During the last ten years, 109 medical cases of traumatic hand nerve lesions have been observed, implicating 78 big nerves (median 35, cubital 42, radial 1) and 37 little nerves (median 35, cubital 42, radial 1) and 37 little nerves (interosseous, collateral, digital). 81 "mixte" epiperineural sutures have been realized (according to a technical proceeding purposed by one of the authors since 1970, and practised with the only aid of a simple optical increase by dissection's magnifying-glasses) : In the same time, 38 neurilemmatic sutures have been seen at second hand and their clinical results noted. 64+ of the global results are very good or "good" concerning the "mixte" epiperineural sutures against 34% for the neurilemmatic sutures. To note : the best quality of the results for the median nerve as well for the primitive sutures, and unfavourable influence of the associated lesions.
