Preoperative Symptom Duration Influences Neurological Recovery and Patient　Reported Outcome Measures After Surgical Treatment of Cervical Ossification of the Posterior Longitudinal Ligament

Abstract

A prospective multicenter study. Objective: To investigate the effect of preoperative symptom duration on neurological recovery for the treatment of cervical ossification of the posterior longitudinal ligament (OPLL). Summary of Background Data:The optimal timing to perform surgery in the setting of cervical OPLL remains unknown. It is important to know the influence of symptom duration on postoperative outcomes to facilitate discussions regarding the timing of surgery.
