Prospective clinical assessment of the interobserver reliability of the Thoracolumbar Injury Classification and Severity Score (TLISS) in a series of consecutive patients. ⋯ The significant improvements observed in interobserver reliability of the TLISS system suggest that the classification system can be taught effectively and be readily incorporated into daily practice. The strong correlation values obtained at the second assessment time suggest that the TLISS system may be reproducibly used to describe thoracolumbar injuries.

Comparative Study
Release of cobalt and chromium ions into the serum following implantation of the metal-on-metal Maverick-type artificial lumbar disc (Medtronic Sofamor Danek).
Cross-sectional study of 10 patients to measure the serum levels of cobalt and chromium after TDA. ⋯ Significant systemic release of Cr/Co was proven in the serum compared with the control group. The concentrations of Cr/Co measured in the serum are similar in terms of their level to the values measured in THA metal-on-metal combinations or exceed these values given in the literature. Long-term implication of this metal exposure is unknown and should be studied further.

Comparative Study
Reoperation rates following lumbar spine surgery and the influence of spinal fusion procedures.
Retrospective cohort study using a hospital discharge registry of all nonfederal acute care hospitals in Washington state. ⋯ Patients should be informed that the likelihood of reoperation following a lumbar spine operation is substantial. For spondylolisthesis, reoperation is less likely following fusion than following decompression alone. For other degenerative spine conditions, the cumulative incidence of reoperation is higher or unimproved after a fusion procedure compared to decompression alone.

Case Reports
Fulminating septicemia secondary to oxygen-ozone therapy for lumbar disc herniation: case report.
A case report and clinical discussion. ⋯ This case report identifies a rare and fatal complication of oxygen-ozone therapy in the treatment of a herniated lumbar disc. Acute fatal septicemia should be considered among the major complications of the oxygen-ozone therapy in the treatment of a herniated lumbar disc.

Comparative Study
Sarpogrelate hydrochloride, a 5-HT2A receptor antagonist, attenuates neurogenic pain induced by nucleus pulposus in rats.
An in vivo study using a rat lumbar disc herniation model. ⋯ Sarpogrelate attenuated pain-related behavior induced by the nucleus pulposus in the animal model. Although further investigation is needed concerning the mechanism of action, this study supported the hypothesis that sarpogrelate is efficacious for treating the pain of lumbar disc herniation.
