Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of 2 lumbar total disc replacements: results of a prospective, randomized, controlled, multicenter Food and Drug Administration trial with 24-month follow-up.
This was a prospective, randomized, controlled multicenter study with 24-month follow-up. ⋯ This prospective, randomized, controlled study comparing 2 TDRs, the first to the authors' knowledge, found the devices produced very similar clinical outcomes. Both groups improved significantly by 6 weeks postoperatively and remained improved throughout follow-up with a high patient satisfaction rate.

Review Case Reports
Atypical fungal vertebral osteomyelitis in a tsunami survivor of the Great East Japan Earthquake.
Case report. ⋯ We report a rare case of the fungal vertebral osteomyelitis caused by S. apiospermum. If a patient develops severe back pain after a near-drowning episode in dirty water such as a swamp or a river, the clinician should be suspicious of the possibility of fungal spondylitis by S. apiospermum.

Retrospective study. ⋯ It seems that upper cervical levels are more likely to degenerate and to have more advanced degrees of degeneration than the lower cervical levels. As expected, age correlates with worsening degeneration. The proposed computed tomographic grading system for cervical facet arthrosis seemed to be reliable.

Case Reports
Traumatic expulsion of T4 vertebral body into the spinal canal treated by vertebrectomy and spine shortening.
A case report. ⋯ Total vertebrectomy and spinal shortening are safe and replicable procedures applicable in few patients with paraplegia. A surgical procedure after 3 weeks makes a complete reduction and a perfect sagittal alignment of the spine difficult to be obtained.

A questionnaire survey. ⋯ There has been a significant decrease in the number of surgeons using high-dose steroids for acute SCIs. Sepsis, gastrointestinal bleeding, and an injury occurring more than 8 hours prior to presentation were agreed upon as contraindications to steroid use.
