Abstract
Objective:
The purpose of this study is to review the results of two surgical methods of simple decompression for treatment of cubital tunnel syndrome.
Methods:
Surgical procedure of simple decompression of the ulnar nerve using the conventional method requires a relatively long incision of 6-8 cm. Later with accumulating experience, we performed simple decompression using a skin incision of 2 cm or less. Between November 2005 and July 2010, simple decompression using the conventional method was performed in 10 elbows (Group 1), and simple decompression using the small skin incision method was performed in 10 elbows (Group 2). The surgical outcome was evaluated and the two groups were compared using a modified Bishop scoring system. We also compared the operation time and hospital stay between the two groups.
Results:
There were no significant differences in the outcomes between the two groups using the modified Bishop scoring system (p＞0.05). Also, there were no significant differences in the postoperative electrodiagnostic study results between the two groups (p＞0.05). However, the operation time and hospital stay were significantly shorter in Group 2 (p ＜0.01).
