OPLL
Also written as: OPLL — ossification of the posterior longitudinal ligament
Ossification of the posterior longitudinal ligament causing spinal cord compression.
Full Definition
OPLL refers to the pathological calcification and ossification of the posterior longitudinal ligament, most commonly affecting the cervical spine. This condition is more prevalent in Asian populations and can cause progressive myelopathy due to spinal cord compression. The ossified ligament appears as a continuous or segmented hyperostotic lesion on imaging studies. Treatment options include anterior decompression with corpectomy or posterior decompression with laminoplasty, depending on the extent and configuration of the ossification.
