A reliability assessment of standardized magnetic resonance imaging (MRI) interpretations and measurements. ⋯ The imaging characteristics of spinal stenosis assessed in this study showed moderate to substantial reliability; future studies should assess whether these findings have prognostic significance in SPS patients.
-
Retrospective cohort study. ⋯ Initial CT imaging identified all unstable cervical spine injuries in obtunded trauma patients. Subsequent upright radiographs did not identify any additional injuries but significantly delayed spine clearance.

Comparative Study
Standing balance and sagittal plane spinal deformity: analysis of spinopelvic and gravity line parameters.
Prospective study of 131 patients and volunteers recruited for an analysis of spinal alignment and gravity line (GL) assessment by force plate analysis. ⋯ Increasing SVA in standing subjects leads to a posterior pelvic shift in relation to the feet. However, no significant difference in GL-heel offset is noted with increasing SVA. It thus appears that pelvic shift (in relation to the feet) is an important component in maintaining a rather fixed GL-Heels offset even in the setting of variable SVA and trunk inclination.

At the end of lumbar microdiscectomy, we administered an emulsion of low-dose epidural morphine and vaseline sterile-oil as carrier for morphine delivery. ⋯ Epidural application of morphine-vaseline sterile-oil compound after lumbar microdiscectomy proved to be safe and effective, improving postoperative pain control and return to function. At clinical and neuroradiological follow-up epidural fibrosis was acceptable. To confirm the efficacy of the compound, large prospective studies are warranted.

Preoperative review of a prospective study, single institution, consecutive series. OBJECTIVE.: To analyze the intermediate-term follow-up of consecutive adolescent idiopathic scoliosis (AIS) patients treated with pedicle screw constructs. ⋯ This is the largest (N = 114), consecutive series of North American patients with AIS treated with pedicle screws having a minimum of 3-year follow-up. The average curve correction was 68% for the main thoracic, 50% for the proximal thoracic, and 66% for the thoracolumbar/lumbar curve at final follow-up.
