BACKGROUND: Muscle-in-vein conduits are a good alternative solution to nerve autografts for bridging peripheral nerve defects since enough graft material is available and no loss of sensation at the harvesting area is expected. The purpose of this study was to compare regeneration results after digital nerve reconstruction with muscle-in-vein conduits, nerve autografts, or direct suture. PATIENTS AND METHODS: 46 patients with 53 digital nerve injuries of the hand subjected to direct suture (n = 22) or reconstruction of 1-6 cm long defects with either nerve autografts (n = 14) or muscle-in-vein conduits (n = 17) between 2008 and 2012, were examined using the two-point discrimination and Semmes-Weinstein Monofilaments. RESULTS: The follow-up examinations took place 12 to 58 months after surgery. A median reduction of sensibility of 2 Semmes-Weinstein monofilaments compared with intact digits was observed after direct suture (DS) and of 2.5 and 2 Semmes-Weinstein monofilaments after reconstruction with autologous nerve grafts (ANG) and muscle-in-vein conduits (MVC), respectively. No statistically significant differences between all three groups could be found with a significance level set by a P < 0.006 (PDS-ANG = 0.24, PDS-MVC = 0.03, PANG-MVC = 0.52). After harvesting a nerve graft, reduction of sensibility at the donor site occurred in 10 of 14 cases but only in one case after harvesting a muscle-in-vein conduit. CONCLUSIONS: Muscle-in-vein conduits may be a good alternative solution to autografts for the reconstruction of digital nerves, since no significant differences could be demonstrated between the two methods.
