PG - e288-e295 LID - S1878-8750(22)00004-3 [pii] LID - 10.1016/j.wneu.2022.01.001 [doi] AB - OBJECTIVE: To assess differences in postoperative patient-reported outcome measures (PROMs) and minimal clinically important difference (MCID) attainment following single-level anterior cervical discectomy and fusion based on predominant preoperative pain symptom. METHODS: Patients undergoing primary, single-level anterior cervical discectomy and fusion were identified. PROMs included visual analog scale (VAS) arm and neck, 12-item short-form physical component summary (SF-12 PCS), Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), and Neck Disability Index, collected preoperatively and postoperatively. Patients were placed in preoperative predominant arm pain (pAP) and preoperative predominant neck pain groups. chi(2) test compared demographic and perioperative characteristics, and MCID attainment rates. Student t test evaluated change from preoperative to postoperative PROM values and compared PROMs between groups. RESULTS: There were 110 patients assessed (52 neck pain, 58 arm pain). Patients with preoperative predominant neck pain improved significantly from preoperative to postoperative at 12 weeks to 1 year for PROMIS-PF, 6 months and 1 year for SF-12 PCS, 6 weeks to 1 year for VAS neck, 6 weeks to 6 months for VAS arm, and 6 weeks to 2 years for Neck Disability Index (all P
