Laminoplasty compared to laminectomy and fusion for degenerative cervical myelopathy: a cost-utility analysis.

ABSTRACT:

Background

Degenerative cervical myelopathy (DCM) is a leading cause of spinal cord dysfunction in adults. Posterior surgical options include laminoplasty (LP), a motion-preserving procedure, and laminectomy with fusion (LF), which offers stabilization but at higher cost. A cost-utility comparison of these approaches is lacking.

Methods

We conducted a cost-utility analysis using a 5-year Markov state-transition model from a healthcare payer perspective. The study cohort was drawn from 3 multicenter prospective studies of patients with DCM. To reduce baseline confounding, patients who underwent LF or LP were matched 2:1 using propensity score matching. Quality-adjusted life years (QALYs) were derived from SF-6D utilities calculated from SF-36 scores at baseline and 12 months.
