A case report. ⋯ This case supports the concept of the existence and clinical relevance of the fourth column of the thoracic spine, and its role in giving added spinal stability.

Case Reports
Iatrogenic disability and narcotics addiction after lumbar fusion in a worker's compensation claimant.
Case report. ⋯ Patients with chronic low back pain are at risk for receiving ineffective and potentially harmful treatment. A focus on restoring function instead of complete pain relief may lead to better outcomes in these patients.

Electrophysiological analysis using somatosensory-evoked potentials (SEPs) and behavioral assessment using Basso, Beattie, Bresnahan (BBB) scale were compared over time for graded Multicenter Animal Spinal Cord Injury Study (MASCIS) contusion spinal cord injury (SCI). ⋯ SEP amplitudes and BBB scores decrease corresponding to increase in injury severity, however, these show different temporal patterns of recovery. These results demonstrate the utility of SEPs in conjunction with BBB, to monitor therapeutic interventions in SCI research.

Randomized Controlled Trial Comparative Study
Lumbar microdiscectomy with spinal anesthesia: comparison of prone and knee-chest positions in means of hemodynamic and respiratory function.
Prospective clinical study to compare the physiologic changes in lumbar disc surgery regarding to positions. ⋯ In conclusion, spinal anesthesia is appropriate for lumbar disc surgery with respect to the hemodynamic parameters in both prone and knee-chest positions, however, in terms of pulmonary functions, the knee-chest position can cause a restrictive effect. Therefore this position should be used cautiously in higher-risk patients.

Systematic review. ⋯ Malposition is the most commonly reported complication of thoracic pedicle screw placement, at a rate of 15.7% per screw inserted with postoperative computed tomography scans. The use of pedicle screws in the thoracic spine for the treatment of pediatric deformity has been reported to be safe despite the high rate of patients with malpositioned screws (11%). Major complications, such as neurologic or vascular injury, were almost never reported in this literature review of case series. Cases reports on the other hand have started to identify such complications.
