Spine
-
A cadaver and radiological study. ⋯ The precise projection of nerve roots to the posterior aspect of spine and intraspinal take-off angles at the sagittal plane have been presented. Surgical interventions of the lumbar disc and nerve root may benefit from this quantitative anatomical study.
-
A retrospective analysis was performed. ⋯ To our knowledge this study demonstrates the first reported SSEP alerts that were associated with a posterior lumbar interbody cage placement without a corresponding EMG alert.
-
A 12-year prospective study of pre-existing and de novo degenerative lumbar scoliosis (DLS) among community-based female volunteers. ⋯ This study indicated that younger age, smaller L4 size, lower LL, greater DLS angle, and L4 tilt at baseline should be evaluated as predictors of progression of pre-DLS. Early signs of asymmetric disc degeneration and smaller L4 size should also be evaluated as predictors of development of de novo DLS.
-
A large-scale analysis of radiographical results of patients with cervical spondylotic myelopathy and a review of the literature. ⋯ Sagittal alignment was slightly changed, with only a 1.8° increase in lordosis. The ROM of the cervical spine was preserved by 87.9%. This preservation of alignment and ROM might be attributable to improvements including early removal of the cervical orthosis, postoperative neck exercises, and some surgical modifications.

Randomized Controlled Trial
Acetaminophen improves analgesia but does not reduce opioid requirement after major spine surgery in children and adolescents.
A randomized, placebo-controlled, double-blind study to evaluate the effect of intravenously (IV) administered acetaminophen on postoperative pain in children and adolescents undergoing surgery for idiopathic scoliosis or spondylolisthesis. ⋯ IV-administered acetaminophen 90 mg/kg/day, adjuvant to oxycodone, did improve analgesia, but did not diminish oxycodone consumption during 24 hours after major spine surgery in children and adolescents. All acetaminophen concentrations were in nontoxic levels.
