Recently we have experimented witn the treatment of three cases associated with OPLL and OYL in the thoracic spine. For three cases with myelopathy we carried out resection of the OPLL and OYL using the posterior and lateral approach. Results of them were good, but one case needed Halo-pelvic apparatus for post-operative instability.
