Cubital tunnel syndrome - Simple nerve decompression or decompression with subcutaneous anterior transposition?

The purpose of this prospective, randomised and controlled study was to evaluate which kind of operative technique for treatment of cubital tunnel syndrome is favourable: subcutaneous anterior transposition or nerve decompression without transposition. This study included 66 patients suffering from pain and/either neurological deficits with clinically and electrographically proven cubital tunnel syndrome. 32 patients underwent nerve decompression without transposition, whereas 34 underwent subcutaneous transposition of the nerve. Follow-up examinations evaluating pain, motor and sensory deficits as well as motor nerve conduction velocities were performed three, nine and 24 months post-operatively. Irrespectively of operative procedures (simple decompression vs. subcutaneous anterior transposition) there were no significant differences between the outcomes of the two groups at either postoperative follow-up examination (p > 0.05).
