Abstract

Among many techniques independently reported to manage neuroma formation, manipulation of the nerve stump inside muscle and vein is the most advantageous technique. This study aimed to enrich the basic data of macroscopic appearance and histo-pathology regarding which technique generates less neuroma: nerve stump implantation inside vein or inside muscle. An experimental study with posttest-only control-group design was conducted in 24 rats that were randomly arranged into 3 groups. One centimeter of the lateral branch of the right ischiadic nerve was cut. Group A served as the control group, where the proximal nerve stumps were left as they were after the excision; whereas the stumps of groups B and C were implanted inside muscles and veins, respectively. The samples were assessed with histologic examination after 4 weeks to measure the morphometric changes in the nerve endings. The data were statistically analyzed with t test. All rats healed uneventfully. No thrombosis was found within group C, and the stumps were free of neuroma formation. The muscle group formed smaller neuroma than the control group. Statistical analysis showed significant differences between the groups (P < 0.05). The outcome of nerve stump implantation inside the lumen of a vein is superior to the implantation inside a muscle in preventing neuroma formation.
