AIM: Several studies have been conducted for the prevention of neuroma and recently published experimental studies include interventions on epineurium. The techniques which include interventions on epinerium were compared to reveal the role of epinurium in neuroma prevention. MATERIAL E METHODS: 55 Sprague-Dawley rats were divided into five groups. Two of the groups were negative and positive controls. The proximal nerve stump was left “free” in the negative control group, while the stump was implant-ed in a muscle pocket in the positive control group following sciatic nerve transection. Experimental groups include epineural ligation, epineural stripping and epineural capping procedures. Follow-up period was six months. After sacri-fication of the rats, histopathologic and immunohistochemical examinations were conducted as well as real-time PCR studies for the assessment. Statistical analysis was performed. RESULTS: The most prominent neuroma formation was detected in the epineural capping group, while the least neuro-ma was observed in the epineural ligation group. DISCUSSION: Statistically significant differences were obtained when the three experimental groups were compared with both control groups. Interestingly there was no significant difference in-between the control groups in terms of preventing neuroma formation. CONCLUSION: epineural ligation group were found to be superior to both control groups as well as experimental groups. Use of epineural capping was concluded to increase the formation of neuroma rather than preventing. Intramuscular implantation of nerve stump had no preventive effect on neuroma formation.
