INTRODUCTION: The laminoplasty has been the most widely used surgical method for OPLL. In recent years, increasing attention has been drawn to the anterior operative approaches for surgical treatment of cervical OPLL. However, which method is the optimum selection for therapy of cervical OPLL is still obscure. Therefore, we performed this prospective nonrandomized clinical studyin patients with multilevelcervical myelopathydue to OPLL and compare thetherapeutic efficiencyof laminoplastyand anterior approach (cervical discectomy and/or cervicalcorpectomy) in the management of multi-level cervical OPLL...

BACKGROUND: In multilevel ossification of the posterior longitudinal ligament (OPLL), laminectomy is an effective surgical technique; however, there is a possibility of kyphotic alignment change after surgery. Nevertheless, in the continuous type of OPLL, the ossification foci are connected and may act as stabilizers preventing alignment change. We here compare the surgical outcome of laminectomy and laminoplasty in continuous-type OPLL of the cervical spine. METHODS: Seventy-three patients who underwent cervical laminectomy or laminoplasty for continuous-type OPLL from 2004 to 2014 were enrolled...

A 7-month-old boy presented with gastrointestinal disturbance, mild neurologic deficit of the left lower extremity and levo-scoliosis of the thoracic spine. Magnetic resonance imaging demonstrated a large intramedullary lesion involving the thoracic spine, from level T1 to T11. Histologic analysis showed a glial tumor with fibrillary processes arranged in radial pattern around mucoid fibrovascular cores with a high proliferative index (focally up to 80%) and prominent vascular endothelial hyperplasia. These findings were consistent with an anaplastic myxopapillary ependymoma...

BACKGROUND CONTEXT: Open door laminoplasty (ODLP) can also lead to significant postoperative motion restriction that further increases over time, for which one of the possible factors is the bony impingement between neighboring posterior bony arches. Previously, we reported this phenomenon and modified technique of ODLP, wedge-shaped resection of the posterior bony arch that produced greater range of motion (ROM) of the cervical spine and less posterior neck pain compared with conventional ODLP (cODLP) in 1-year follow-up time, but no longer follow-up outcomes of the surgical technique has been reported...
