Abstract:
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. Muscle Nerve 55: 698-705, 2017.
