This 2007 meta-analysis pooled four RCTs to directly compare simple decompression (incision of the Osborne band) versus anterior ulnar nerve transposition — subcutaneous or submuscular — for cubital tunnel syndrome in patients with no prior elbow trauma or surgery, using clinical scores and motor nerve-conduction velocity as outcomes.
When operating on a cubital tunnel patient without prior elbow trauma or surgery, simple decompression is a defensible first-line choice — Level I evidence shows equivalent clinical and electrodiagnostic outcomes versus anterior transposition, with less dissection, preserved nerve vascularity, and lower cost.
Reserve transposition for cases with confirmed ulnar nerve instability, though even that subgroup showed no statistically significant outcome difference in the available data.
