C2-Involving Cervical Ossification of the Posterior Longitudinal Ligament (OPLL): Dome-like Laminoplasty Versus Laminectomy With Fusion.

ABSTRACT: Study DesignRetrospective cohort study.ObjectivesTo compare the outcomes of C2 dome-like laminoplasty (C2-Dom LP) and C2 laminectomy with fusion (C2-LF) in patients with C2-involving ossification of the posterior longitudinal ligament (OPLL) and to identify radiological predictors that guide optimal surgical selection.MethodsA retrospective analysis of 143 patients (C2-Dom LP, 71; C2-LF, 72) was performed. Radiological evaluations were C2 cross-sectional area (CSA), cervical range of motion (ROM), canal-occupying ratio, and sagittal alignment parameters. Clinical outcomes were assessed using Japanese Orthopedic Association (JOA) scores, neck disability index, and visual analog scale. Subgroup analysis was conducted according to canal compromise severity. A propensity-matched analysis using
