: Average follow up was 9.6 months in the transposition group and 16.0 months in the nontransposition group. Transposition of the ulnar nerve was found to be an independent variable associated with ulnar neuritis (P<0.001). The incidence of ulnar neuritis was 33% (16 of 48) with transposition and 9% (eight of 89) without transposition (P = 0.0003)
