Prospective consecutive series. ⋯ Video-assisted thoracoscopic surgery provides a safe and effective alternative to open thoracotomy in the treatment of thoracic pediatric spinal deformities. The procedure remains time consuming.

Case report: whiplash-associated disorder from a low-velocity bumper car collision: history, evaluation, and surgery.
Case report of a patient with a whiplash-associated disorder following a bumper car collision. Imaging studies failed to provide an anatomic explanation for the debilitating symptoms. ⋯ This case of whiplash-associated disorder after a low-velocity collision highlights the difficulty in defining threshold of injury in regard to velocity. It also illustrates the value of computerized motion analysis in confirming the diagnosis of whiplash-associated disorder and in the evaluation of prognosis and treatment.

A retrospective descriptive assessment of the clinical and radiologic outcomes of 11 patients who underwent transpedicular decompression for thoracic spine tuberculosis. ⋯ Our results show that the transpedicular approach is a viable and safe surgical option for ventral decompression in thoracic spine tuberculosis, followed by chemotherapy for 18 months and immobilization in an alkathene shell for 3 months.

Cerebrospinal fluid biomarkers were evaluated in a setup using established pig models to mimic clinical disc herniation. ⋯ The present study demonstrates increased concentrations of neurofilament and nociceptin in cerebrospinal fluid after nerve root compression. A simultaneous application of nucleus pulposus did not increase the response.

An experimental study using a sheep cervical spine interbody fusion model. ⋯ After 12 weeks, there was no significant difference between the bioabsorbable poly(l-lactide-co-d,l-lactide) cage and the tricortical bone graft. In comparison to the tricortical bone graft, the bioabsorbable polymer-calciumphosphate composite cage showed significantly better distractive properties, a significantly higher biomechanical stiffness, and an advanced interbody fusion; however, six of eight polymer-calciumphosphate composite cages cracked. Although the fate of the foreign body reactions and the cracks is currently unclear for both bioabsorbable cages, the early appearance of large osteolysis associated with use of the poly(l-lactide-co-d,l-lactide) cage allows skepticism regarding the value of this bioabsorbable implant.
