Retrospective case series on long-term follow-up results of original expansive open-door laminoplasty for cervical myelopathy due to cervical spondylosis (CSM) and ossification of posterior longitudinal ligament (OPLL). ⋯ Long-term results of open-door laminoplasty without bone graft, graft substitutes, or instruments were satisfactory. However, segmental motor paralysis, kyphosis, established before and after surgery, OPLL progression, and late deterioration due to age-related degeneration remain challenging problems.

Retrospective single-center study. ⋯ MPSS should be administered to patients with incomplete cervical spinal cord injury according to the Second National Acute Spinal Cord Injury Study protocol.
-
The intraoperative findings of the local pressure of the intervertebral foramen and the electrophysiologic values of the spinal nerve roots were evaluated. ⋯ Our findings suggested that a double compression of the nerve root exists in lumbar spinal stenosis with lumbar spine extension, which includes the spinal canal and the vertebral foramen.

Recent literature regarding the psychological impact of scoliosis was reviewed. ⋯ Adolescent patients with scoliosis may experience psychosocial difficulties, especially while undergoing treatment for scoliosis. Interventions aimed at managing psychosocial or body image disturbances may help to ameliorate the potentially negative impact of scoliosis on these facets of life.

To examine changes in substance P receptors on dorsal root ganglion cells innervating the rat lumbar intervertebral discs using immunohistochemistry and a retrograde neurotracing method. ⋯ Substance P-saporin decreased the ratio of neurokinin-1 immunoreactive neurons innervating the disc related to discogenic low back pain. Substance P-saporin may be a useful tool to investigate the mechanism of discogenic low back pain.
