Abstract

Background: Median and ulnar nerve injuries are common, whether isolated or combined injury of both nerve. A nerve graft, if performed in a tensionless manner, has been shown to generally have better results than an end-to-end approximation performed under tension. Objective: The aim of this study is to analyze the longterm results of sensory recovery after secondary reconstruction median and ulnar nerve by autograft in patients who were treated on Clinic for Plastic and Reconstructive Surgery in the period from January 1st 1993 to December 31st 2005. We analyzed the influence of the patients age, level of injury, the size of the graft and the period between the injury and operation on the late results. Patients and methods: Evaluation was performed in 55 patients with adequate follow-up. The mean follow-up period was 3,9 years. Reconstructions were applied on the median nerve in 31 patients and ulnar nerve in 24 patients. Criteria for inclusion in the study was median and ulnar nerve grafting in the forearm region. Patients were divided by age in two groups, below 25 and over 25 years, by injury level in the distal and proximal forearm injuries, by the length of autograft up to 5 cm and other group with graft length over 5 cm, by the period between injury and operation in group with denervation time up to 6 months and the group with denervation time over 6 months. Rating of sensibility was presented on the Highet Scale as modified by Dellon and more precise rating of sensibility was presented by Moberg’s rating scale of sensibility. Calculation of frequencies and percentual values was performed for all included variables. For establishment of differences between the frequencies the ÷2 – test was used (Chi square test) at the level of statistical importance (p
