Differences were evaluated with chi-square statistics, except for “age at the time of the first surgery,” where one-way ANOVA was used. Statistically significant differences are marked in bold. Values are mean (SD), percentage, and count (n). MRI: magnetic resonance imaging. a values for electrophysiology and MRI are based on the examinations evaluating affection of the ulnar nerve and spinal nerve root(s), respectively.
