Posterior Decompression for Cervical Ossification of the Posterior Longitudinal Ligament
Characteristics of ossification of the posterior longitudinal ligament (OPLL) in the cervical spine are (1) reducing the space available for the spinal cord (SAC) and causing compressive myelopathy, (2) extending cranially to C2 or above, (3) diminishing the cervical rangeof-motion, and (4) generally occurring in older people over 50 years old. The basic strategy of treatment in patients with myelopathy caused by cervical OPLL is decompression for the cervical cord and removal of OPLL if readily done.
