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.

The results of vascularized-free fibular grafts in complex spinal reconstruction.
Retrospective review. ⋯ Vascularized-free fibular grafts are effective in the treatment of complex spinal reconstruction after surgery for spinal tumors or osteomyelitis. The vascularized-free fibular graft adds structural support as well as living bone to the fusion site and is a reasonable alternative to nonvascularized grafts in locally compromised surgical beds.

Clinical outcomes of posterior lumbar interbody fusion for lumbar foraminal stenosis: preoperative diagnosis and surgical strategy.
A retrospective case study of the use of posterior lumbar interbody fusion (PLIF) to treat lumbar foraminal stenosis (LFS). ⋯ Lumbar foraminal stenosis could be reliably diagnosed by distinctive clinical symptoms, and various radiographic examinations such as plain x-ray, Magnetic resonance imaging, and 3D-reconstraction computed tomography. The PLIF procedure, in combination with segmental pedicle screws, interbody cages, and autogenous local bone graft provides excellent clinical outcomes, and is a rational and useful surgical option for lumbar foraminal stenosis.
