Original article: Surgical treatment of multilevel cervical radiculomyelopathy caused by the concomitant ossification of the ligamentum flavum and the posterior longitudinal ligament

A two-stage operation is essential for patients with cervical spine myelopathy that is the result of concomitant ligamentum flavum and posterior longitudinal ligament ossification. Modified open door laminoplasty with a miniplate and screw from the posterior approach was carried out first. Then anterior decompression and fusion with a Casper plate and Surgibone at the C5-6 intervertebral space were carried out 1 week after the first operation. One week after the second procedure, the postoperative Nurick score improved from four to two. The patient withstood the whole procedure well and within one week was noted to have improved muscle strength. The two-stage operation is a safe and effective choice for treating concomitant OPLL and OLF in the cervical spine with radiculomyelopathy. [PUBLICATION ABSTRACT]
