Compressive myelopathy in severe angular kyphosis is rare and challenging for surgical treatment. The goal of this retrospective study was to report a series of ten patients with compressive myelopathy in severe angular kyphosis and the results of surgical decompression and correction of kyphosis. ⋯ Compressive myelopathy in severe angular congenital kyphosis is usually occurred high incidence rate at apex of upper thoracic spine (T1-T4). The duration from onset of paraplegia until surgery and the severity of paraplegia before surgery are two key factors for neurological prognosis after surgery.

To characterize the distribution of nerves within a single S1 vertebral body, with particular emphasis on the superior endplate that interfaces with the L5/S1 disc. ⋯ Our results demonstrate that the S1 body and endplate are densely innervated and the peak in nerve density at the vertebral center coincides with vasculature patterns previously described in lumbar vertebral bodies. In the sacrum, however, there is no posterior nutrient foramen that facilitates nerve penetration through the vertebral cortex. Rather, our data indicate that nerves penetrate the S1 via the lateral aspects, consistent with being branches of the anterior sacral nerve. Since PGP 9.5 is a ubiquitous neural marker these identified nerves are likely composed of a mixed population of nociceptive and autonomic fibers.

The clinical impact of the coexistence of compressive cervical myelopathy (CM) and/or lumbar spinal canal stenosis (LCS) with compressive thoracic myelopathy (TM) remains unknown. The purpose of this study was to examine the incidence, clinical pictures, and surgical outcomes of patients with compressive TM and the coexistence of compressive CM and/or LCS. ⋯ About 70 % of patients who underwent surgery for TM had concurrent CM and/or LCS, and they were initially diagnosed with CM or LCS. Single-stage multilevel decompression surgery for TM with concurrent CM and/or LCS is comparable to thoracic only surgery with regard to complications and surgical results, and it is well tolerated in elderly patients.

The purpose of the current study was to evaluate the prognostic value of intraoperative improved transcranial motor evoked potential (MEP) after cervical cord decompressive surgery for cervical compressive myelopathy (CCM). ⋯ Patients with intraoperative MEP improvement after cervical cord decompression have better prognosis in early and long-term neurologic recovery in CCM surgery.

To investigate the presence of head control deficits and its course of recovery after anterior cervical discectomy and fusion (ACDF) surgery in cervical spondylotic myelopathy (CSM) patients. ⋯ Adequate C2-C7 cervical lordosis was maintained in the current study with improvement of slow head motion control and ROM at 6-month. However, improvement in head position sense was not maintained and neck strength showed continuous declination overtime. Assessment and monitoring of head control deficits should be routinely considered in CSM patients.
