Conclusions

Classification of OLF, which causes thoracic myelopathy, is based on CT findings and is necessary for choosing the appropriate surgical procedure. When OLF is the lateral, extended, or enlarged type at a single intervertebral level, fenestration (laminotomy) is the surgical choice. For multilevel cases, French-door laminectomy is indicated. For cases of the fused or tuberous type, en bloc laminectomy is indicated. When fused- or tuberous-type OLF is complicated by ossification of the dura mater, en bloc laminectomy with simultaneous removal of the ossified mass and the surrounding dura mater is performed, leaving the arachnoid membrane intact.
