In 1960, Tskimoto first mentioned the spinal cord lesions caused by compression of posterior longitudinal ligament(OPLL), thereafter, hundreds of cases have been reported. There are, however, some controversial opinions concerning the mechanisms of the formation and development of OPLL and questions why a special ligaments, posterior longitudinal ligaments can be calcified, enlarged and compress the cord. And also, there have been many reports describing various surgical method that could manage OPLL, but the OPLL still has many problems in surgical treatment. Recently, the neurosurgical team at the St. Pauls Hospital, encountered and operated on 7 cases of OPLL at cervical area. After all dignostic tests and examinations were done, the morphological classification, combined other lesions and pathological status were verified and analyzed during treatment. The different surgical methods were taken case by case. The authors would like to share with you our experiences of the surgical methods, indications of operation the results and the progrosis of treatment in OPLL.

Intradural lumbar disc herniation (ILDH) is rare. In this report, authors present 2 cases of ILDHs associated with severe adhesion between the dural sac and posterior longitudinal ligament. In a 40-year-old man, ILDH occurred in association with epidural adhesion due to ossification of the posterior longitudinal ligament (OPLL). In other 31-year-old man, ILDH occurred in presence of epidural adhesion due to previous spine surgery.

Ossification of the anterior longitudinal ligament of the spine was first reported by Dr. Forestier and Dr.Rotes in 1950. However, in no other countries but Japan there have been reports on the ossification of the posterior longitudinal ligament of the spine which was first reported by Tsukimoto in 1960. About 45% of ossification of the posterior longitudinal ligament of the spine have a combination of ossification of the anterior longitudinal ligament and yet it is considered to be a variety of the spinal geriatric conditions, favorable to the cervical spine. The condition develops similar symptoms of cervical spondylosis. Authors report two cases of ossification of posterior longitudinal ligament of cervical spine of Korean nationals at St. Marys hospital, Catholic Medical College.

Intradural cervical disc herniation is an extremely rare condition and its pathogenesis is not certain. We experienced a case of intradural cervical disc herniation at the C4-5 level in a 56-year-old man. The preoperative sagittal T1- and T2- weighted images revealed an intradural iso-intensity lesion, with the spinal cord behind the posterior longitudinal ligament at the C4-5 disc level. The post-contrast T1-weighted image revealed a peripheral enhanced intradural lesion. We report here on a case of an intradural cervical disc herniation that was diagnosed by radiological examination, and we include a review of the related literature.

Ossification of the posterior longitudinal ligament (OPLL) is an uncommon disorder that may be associated with slowly progressing neurological symptoms. We encountered a case of acute cervical myelopathy due to a ruptured disc in an asymptomatic patient with OPLL, who was surgically managed by the anterior approach and fusion. We report the case with a review of the relevant literature.
