Stenosis of cervical spinal canal due to ossification of posterior longitudinal ligament

Authors present their experience with 36 cases of spinal canal stenosis due to ossification of posterior longitudinal ligament in cervical spine. Ligament ossification extent was found to be local (1 segment) or segmental (2-3 segments). Clinical examination showed cervical myelopathy of various severity. Diagnosis of cervical spinal canal stenosis was determined mainly by CT and MRT. All patients underwent surgical treatment - anterior transcorporal decompression of spinal cord. Positive results were achieved in 34 patients including 22 patients with complete elimination of myelopathy, 9 patients with partial elimination and 3 patients with stopping of the process progression. In 2 patients, surgical procedure was inefficient.
