Influence of Preoperative Severity on Postoperative Improvement Among Patients With Myeloradiculopathy Following Anterior Cervical Discectomy and Fusion

Study Design: Retrospective cohort. Objective: The aim was to determine how neck pain and disability improve following anterior cervical discectomy and fusion among patients with myeloradiculopathy. Summary of Background Data: Neck pain and disability have traditionally been assessed using the neck disability index (NDI) and visual analog scale (VAS). Few studies have investigated how neck pain/disability improve differently among patients with symptoms of both myelopathy and radiculopathy. Methods: Patients were identified through retrospective review of a prospective surgical database from 2013 to 2020. Patient-reported outcome measures (PROMs) collected included VAS neck and arm, NDI, 12-Item Short Form physical composite score (SF-12 PCS), Patient-Reported Outcomes Measurement Information System physical function (PROMIS PF), and Patient Health Questionnaire 9 (PHQ-9). PROMs were collected preoperatively and up to 1-year postoperatively. Patients were categorized by preoperative symptom severity: high VAS arm (>7); high NDI (>55); high VAS arm and NDI; and moderate symptoms. Linear and logistic regression evaluated the impact of preoperative symptom severity on PROM scores and achievement of minimum clinically important difference (MCID), respectively. Results: A total of 187 patients were included, 98 with neither high VAS arm nor NDI (moderate group), 14 with high NDI, 46 with high VAS arm, and 29 with high NDI and VAS arm. Postoperativel...
