Background: Ossification of the posterior longitudinal ligament (OPLL) is a progressive disorder that mostly involves the cervical spine. It is more prevalent in East Asian countries. Patients typically present with the gradual onset of myelopathy, while about 5% show rapid progression.
Case Description: A 51-year-old diabetic and hypertensive male presented with a left-sided hemiparesis following trivial trauma. The first diagnosis was a stroke, but the subsequent workup proved negative. Subsequently, the MRI and CT studies demonstrated significant cord compression due to OPLL extending from C2 to C7. There was also a heterogeneous hyperintense intramedullary cord signal indicative of edema/myelomalacia in the retro- odontoid region. The CT also diagnosed C2-C7 diffuse idiopathic skeletal hyperostosis.
Conclusion: Patients with cervical myelopathy due to OPLL rarely present about 5% of the time with the acute onset of neurological deficit following minor trauma. Certainly, one must consider high cervical OPLL as responsible for hemiparesis in a patient whose brain MR has ruled out a stroke.

Risk Factors and Prevalence of Sleep Disturbance in Degenerative Cervical Myelopathy.
World Neurosurg

Department of Orthopaedic Surgery and Spinal Surgery, The University of Tokyo, 7-3-1, Hongo, Bunkyo-Ku, Tokyo, 113-8655, Japan; University of Tokyo Spine Group (UTSG), 7-3-1, Hongo, Bunkyo-Ku, Tokyo, 113-8655, Japan.
Background: Sleep disturbances, especially those lasting more than one hour, are under-researched in patients with degenerative cervical myelopathy (DCM). This study aims to investigate the prevalence and risk factors for such disturbances in DCM patients undergoing decompression surgery and to identify factors contributing to poor postoperative improvement.
Methods: A multicenter retrospective observational study was conducted on consecutive patients diagnosed with DCM who underwent cervical decompression surgery between April 2018 and August 2022.

Background: Brown-Séquard syndrome (BSS) is a rare neurological condition characterized by injury to one-half of the spinal cord. In the context of trauma, BSS is typically seen with penetrating injuries. Here, the authors present the unique case of a patient presenting with BSS after blunt trauma.

Department of Spine Surgery, Tianjin Union Medical Center, Tianjin, 300121, China.
Background: The best open side for unilateral open-door laminoplasty (UODL) to treat inconsistent cervical ossification of the posterior longitudinal ligament (OPLL) needs to be identified.
Methods: Thirty-one individuals with inconsistent OPLL who underwent UODL between January 2016 and December 2018 were retrospectively divided into two groups: when the side of the open door was consistent with the side of the larger ossification occupancy area, patients were placed in the Consistent group; when the side of the open door was contralateral to the side of the larger ossification occupancy area, patients were placed in the Contralateral group. The following parameters were evaluated: neck disability index (NDI) score, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, postoperative laminoplasty opening width and angle, and spinal cord diameter ratio.

Background: Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic non-inflammatory disorder characterized by enthesopathy and osteophyte formation. DISH can also cause several other symptoms. Limited range of motion (ROM) is the most common symptom; however, dysphagia and respiratory distress are clinically important symptoms.
