Purpose
To evaluate the clinical results of anterior subcutaneous transposition of the ulnar nerve in patients with moderate to severely impaired cubital tunnel syndrome. Materials and Methods: Thirty seven cases in thirty six patients of cubital tunnel syndrome treated by decompression and anterior subcutaneous transposition between 1995 and 2004, were analyzed clinical results retrospectively. We evaluated the statistical correlation between follow-up period, patient’s symptom duration, age and the clinical results. The average follow-up period was 48 months (12-118). The average age of patients was 47 years (16-73). The patients evaluated by McGowan’s grading system as modified by Goldberg et al. Functional outcomes were evaluated by Akahori’s criteria. Electro-diagnostic studies were analyzed in 22 cases. Results: There were IIb in 6 cases, III in 31 cases. Final results were as evaluated excellent in 11 cases, good in 21 cases, fair in 3 cases, poor in 2 cases. In motor nerve conduction studies, the above-below elbow motor conduction velocity was improved from 31.8 m/s to 41.1 m/s in an average. In sensory nerve conduction studies, sensory action potential amplitude of little finger was improved from 3.6 uV to 9.9 uV in average. There was no statistically significant relationship between patient’s duration of symptom, follow-up period, age, and the clinical results. Conclusion: We could obtained relatively favorable result after decompression and anterior subcutaneous transposition of ulnar nerve in the moderate to severely impaired cubital tunnel syndrome. However, we could not find out statistically significant relationship between patient’s duration of symptom, follow-up period, age and the clinical results as independent factor. |
