Trajectory of transsacral iliac screw for lumbopelvic fixation: a 3-dimensional computed tomography study.
A 3-dimensional multi detector computed tomography study. ⋯ The TSIS could be safely inserted without increasing the general risk of conventional iliac screw. On the basis of the result of this study, we consider the TSIS technique a useful option for lumbopelvic fixation to overcome disadvantages of iliac screw.

Postoperative spinal epidural hematoma after microscopic lumbar decompression: a prospective magnetic resonance imaging study in 89 patients.
A prospective case series. ⋯ The incidence of postoperative SEH after microscopic lumbar decompressive surgery was 14.6%. Postoperative SEH did not delay clinical improvements. Age 50 years old or more was strongly associated with the development of postoperative SEH.

Significance of angular mismatch between vertebral endplate and prosthetic endplate in lumbar total disc replacement.
A retrospective study. ⋯ Angular mismatch was more common in L5-S1 than in L4-5. L-TDR at the most lordotic level, L5-S1, and implantation of an upper prosthesis with a mismatched angle seem to be the causes of a reduced segmental ROM, increased segmental lordosis, and anterior malpositioning of the prosthesis. However, these changes do not affect the clinical outcomes of patients.

Serum monocyte chemotactic protein-1 concentrations distinguish patients with ankylosing spondylitis from patients with mechanical low back pain.
This study aimed to identify potential blood-derived biomarkers distinguishing patients with ankylosing spondylitis from those with mechanical low back pain. ⋯ The MCP-1 serum was identified as a biomarker candidate, distinguishing ankylosing spondylitis from mechanical low back pain with a sensitivity of 96% and a specificity of 83.3%.

Case ReportsFoot drop caused by a lesion in the thoracolumbar spine.
Fifteen patients with foot drop caused by a thoracolumbar spine lesion were retrospectively investigated. ⋯ Prognosis of foot drop was much better when the causative lesion was at the thoracolumbar spine than when it was at the lumbar spine. Severe paralysis was not a poor prognostic factor.
