Abstract

Objectives: Knowledge is scarce about the outcome of revision surgery for recurrent or persistent ulnar nerve entrapmentat the elbow (UNE). We studied the outcome of subcutaneous (SCT) and submuscular (SMT) ulnar nerve transpositionsdue to UNE, analyzing both primary and revision surgeries, aiming to identify predictors for revision surgery.Methods: All surgically treated UNE cases (2004-2008) at our department were studied retrospectively. The initial populationof surgically treated patients included 285 primary and 52 revision surgeries. Forty-three of the former were transpositions(15 SCT and 28 SMT) and 44 (7 SCT and 37 SMT) of the latter, which were the ones included in the present study.Medical records, including electrophysiological protocols, were reviewed and the postoperative outcome was graded as 1)cured/improved, and 2) unchanged/exacerbated symptoms, based on the patient-reported and surgeon-evaluated outcome.Results: The frequency of concomitant systemic diseases (p
