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.

The different surgical methods were taken case by case.
