Predictors of functional outcomes after simple decompression for ulnar neuropathy at the elbow: a multicenter study by the SUN study group.

Abstract Objective To identify predictors of surgical outcome for ulnar neuropathy at the elbow (UNE). Design Prospective cohort followed for 1 year. Setting Clinics. Participants Patients diagnosed with UNE (N=55). Intervention All subjects had simple decompression surgery. Main Outcome Measures The primary outcome measure was patient-reported outcomes, such as overall hand function through the Michigan Hand Outcomes Questionnaire (MHQ). Predictors included age, duration of symptoms, disease severity, and motor conduction velocity across the elbow. Results Multiple regression models with change in the overall MHQ score as the dependent variable showed that at 3 months postoperative time, patients with Conclusions Subjects with
