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.

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.

Comparative Study
Facet joint orientation difference between cephalad and caudad portions: a possible cause of degenerative spondylolisthesis.
A case-control study. OBJECTIVE.: To measure the orientation of the facet joints at both cephalad and caudad portions and to compare them between patients with degenerative spondylolisthesis (DS) and patients with lumbar spinal stenosis (LSS, controls). ⋯ In this study, we confirmed that the cephalad portion of the facet joints were more sagittally oriented and that the caudad portion of the facet joints were more coronally oriented in patients with DS. These findings were observed not only at L4-L5 but also at the uninvolved L3-L4 level in patients with DS at the L4-L5 level.

Decision analysis. ⋯ Our model favors anterior/posterior spinal fusion for surgical correction of large thoracic curves in skeletally immature females. The probability of curve progression after spinal fusion is the main variable that dictates the optimal surgical approach and rates in the literature are based on outdated surgical instrumentation. Future observational studies are warranted to acquire more accurate curve progression rates.
