Laminectomy with posterior wiring and fusion for cervical ossification of the posterior longitudinal ligament, spondylosis, ossification of the yellow ligament, stenosis, and instability: a study of 5 patients.

Cervical laminectomy with posterior wiring and fusion is valuable for the management of cervical ossification of the posterior longitudinal ligament (OPLL), spondylosis, ossification of the yellow ligament (OYL), stenosis, and instability. Within 1.5 years, five patients averaging 73 years of age developed severe myelopathy. Dynamic radiographs confirmed an intact cervical lordosis with active subluxation and instability at one or two levels, whereas magnetic resonance and computed tomography scans showed OPLL, spondylosis, OYL, and stenosis. After multilevel laminectomy with posterior wiring and fusion and immobilization in cervicothoracic orthoses, patients fused in an average of 3.6 months. All patients improved, showing mild to moderate residual postoperative myelopathy an average of 13 months later (range, 6-19 months). With an intact cervical lordosis, laminectomy with posterior wiring and fusion was used successfully to manage five patients with OPLL, spondylosis, OYL, stenosis, and instability.
