Introduction: In this study we aimed to identify prognostic factors of ulnar neuropathy at the elbow (UNE) and developed a scoring system to establish the prognosis. Methods: We collected baseline clinical, electrophysiologic, and ultrasonographic data from 2 cohorts. The outcomes for all patients were determined on follow-up. Prognostic factors were determined using single and multiple variable analyses. A points system was developed to determine the risk for an unfavorable outcome. Results: Of the 220 patients with UNE 178 (81%) could be re-evaluated. Four variables were retained in the prediction model for a points system. An unfavorable outcome was associated with right-sided UNE, more severe weakness of the abductor digiti minimi (ADM), and more pronounced ulnar nerve thickening. A compound muscle action potential amplitude reduction across the elbow of >= 16% (particularly if >= 50%) was associated with a more favorable outcome. Conclusion: Outcome in UNE may be predicted by scoring 4 parameters.
