Randomized Controlled Trial Multicenter Study
The effect of electrical stimulation on lumbar spinal fusion in older patients: a randomized, controlled, multi-center trial: part 2: fusion rates.
Randomized, controlled, multi-center trial. ⋯ Thin slice CT revealed very high nonunion rates after uninstrumented spinal fusion in older patients. DC-stimulation was not effective in increasing fusion rates in this patient population. The achievement of a solid fusion was associated with superior functional outcome.

Case report and literature review. ⋯ Delayed neurologic deterioration after spinal surgery is uncommon. Epidural arteriovenous fistulas with secondary intradural drainage, which are rare, should be considered.

Randomized Controlled Trial Multicenter Study Comparative Study
Degenerative spondylolisthesis: does fusion method influence outcome? Four-year results of the spine patient outcomes research trial.
Clinical trial subgroup analysis. ⋯ In patients with DS and associated spinal stenosis, no consistent differences in clinical outcomes were seen among fusion groups over 4 years.

Randomized Controlled Trial Comparative Study
Corticosteroid injection treatment to the ischiadic spine reduced pain in women with long-lasting sacral low back pain with onset during pregnancy: a randomized, double blind, controlled trial.
Randomized double blind controlled clinical trial. ⋯ The anatomic region around the sacrospinous ligament insertion on the ischial spine is suggested to be one source of long-lasting sacral low back pain with onset during pregnancy. The pain was relieved by slow-release corticosteroid injection treatment to the ischial spine.

Prospective, observational in vivo study. ⋯ Simultaneous epidural and vascular injection accounts for over half of all vascular injections during cervical transforaminal epidural injections. With the risk of severe complications and high incidence of vascular injections in the cervical spine, live fluoroscopy is recommended during contrast injection with specific attention to simultaneous epidural and vascular flow.
