Prognostic factors for surgical outcome in spinal cord injury associated with ossification of the posterior longitudinal ligament (OPLL)
BACKGROUND Ossification of the posterior longitudinal ligament (OPLL) may increase the risk of spinal cord injury (SCI) with various neurological deficits after minor trauma. However, few studies have investigated the influence of OPLL on neurological outcome after acute cord injury. We examined whether severe spinal canal stenosis caused by OPLL affects neurological outcome after SCI based on ...
متن کاملSurgical strategy for ossification of the posterior longitudinal ligament in the cervical spine.
Ossification of the posterior longitudinal ligament is a common cause of cervical myelopathy, and controversy remains regarding surgical options. Between January 2004 and December 2007, a total of 164 patients with ossification of the posterior longitudinal ligament in the cervical spine who underwent surgical treatment at the authors' institution were included in this study. The choice of surg...
متن کاملMultisegmental cervical ossification of the posterior longitudinal ligament: anterior vs posterior approach.
AIMS To determine the surgical approach in patients with multisegmental (four or more segments) OPLL of the cervical spine. METHODS AND MATERIALS Data of 27 patients who had undergone either an anterior (corpectomy with excision of OPLL and interbody fusion = 14 patients) or posterior approach (laminectomy = 12, laminoplasty = 1 patient) for the multisegmental cervical OPLL was analyzed retro...
متن کاملDynamic changes in spinal cord compression by cervical ossification of the posterior longitudinal ligament evaluated by kinematic computed tomography myelography.
STUDY DESIGN A prospective clinical study. OBJECTIVE To investigate the dynamic causative factor in the pathogenesis of myelopathy in patients with cervical ossification of the posterior longitudinal ligament (OPLL) using kinematic computed tomography (CT) myelography. SUMMARY OF BACKGROUND DATA Kinematic CT myelography is useful for dynamically evaluating the cervical spine with high-resol...
متن کاملSignificance of Intramedullary High Signal Intensity on Magnetic Resonance Imaging in Patients with Cervical Ossification of the Posterior Longitudinal Ligament
BACKGROUND The purpose of this study was to analyze the relation between intramedullary high signal intensity (IMHS) on magnetic resonance imaging (MRI), radiographic parameters, and clinical symptoms in cervical ossification of the posterior longitudinal ligament (OPLL) patients. METHODS Two hundred forty-one patients, who underwent simple radiography, computed tomography (CT), and MRI were ...
