Laminoplasty for thoracic and lumbar spine surgery enables surgeons to preserve the posterior arch of the spine while preventing invasion of hematoma and scar tissue, postoperative instability, subluxation, and kyphotic deformities. The authors have developed a new surgical technique: namely, transverse placement laminoplasty (TPL) using titanium(More)
Fourteen patients who had cervical spine surgery for cervical spondylotic myelopathy with median-nerve short-latency somatosensory-evoked potentials (SSEP) were followed preoperatively and until six months postoperatively. We evaluated the N18 latency and compared it with the JOA score recovery rate for each period. Seven patients demonstrated improvement(More)
STUDY DESIGN Nerve root blood flow was intraoperatively measured before and after discectomy for lumbar disc herniation and compared with clinical features. OBJECTIVE To investigate the relation between nerve root blood flow changes and symptoms associated with lumbar disc herniation. SUMMARY OF BACKGROUND DATA Several authors have reported that(More)
STUDY DESIGN The intraoperative findings of the local pressure of the intervertebral foramen and the electrophysiologic values of the spinal nerve roots were evaluated. OBJECTIVE To investigate the neurophysiologic changes of the spinal nerve roots in the vertebral foramen. SUMMARY OF BACKGROUND DATA As far as we know, few reports have so far described(More)
STUDY DESIGN The clinical relationship between the local pressure of the intervertebral foramen and the clinical findings in lumbar spinal canal stenosis were evaluated. OBJECTIVE To investigate the pathogenesis of neurogenic intermittent claudication in lumbar spinal canal stenosis. SUMMARY OF BACKGROUND DATA The genesis of neurogenic intermittent(More)
STUDY DESIGN The sagittal kinematics of the cervical spine was evaluated using kinematic magnetic resonance imaging (kMRI). OBJECTIVE To investigate the effect of degenerative changes in the functional spinal unit on cervical kinematics by using kMRI. SUMMARY OF BACKGROUND DATA Few studies have, thus far, by using MR images, described the contribution(More)
