A retrospective review of the cervical extension osteotomy in the past 36 years for the treatment of flexion deformity of patients with ankylosing spondylitis was conducted. ⋯ The sitting position with local anesthesia is safe and allows for correction of deformity in a controlled manner. The increased lateral resection area reduces the possibility of nerve root impingement and provides ample room for the spinal cord. The cranial halo can also be adjusted after surgery to modify the head/neck position and can be adjusted to alleviate any C8 nerve root impingement. The procedure demands great attention to detail to minimize risk.

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.

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.
