Randomized Controlled Trial
Comparison of Cervical Range-of-Motion Restriction and Craniofacial Tissue-Interface Pressure with 2 Adjustable and 2 Standard Cervical Collars.
Randomized controlled trial. ⋯ All collars, compared with no collar, significantly restricted CROM. Although the collar-to-collar comparisons were statistically significant, the differences may have little clinical significance in the acutely injured trauma patient. The Miami J standard collar had the lowest overall TIP in both sites and positions. Ongoing effort should be devoted to staff education in proper sizing and fit, particularly for patients with high BMI.

Randomized Controlled Trial
Comparison of 1-Level Versus 2-Level Anterior Cervical Discectomy and Fusion: Clinical and Radiographic Follow-Up at 60 Months.
This study represents a posthoc analysis of data collected from 2 control arms of a prospective, randomized study. ⋯ One- and 2-level ACDF groups improved significantly and maintained improvement throughout 60 month follow-up. When comparing groups, outcomes were often similar, though the 1-level group demonstrated higher fusion rates at 6 and 12 months, greater improvement in NDI scores from 18 to 60-month follow-up, and greater improvement in SF-12 PCS from 12 to 60 months.

Retrospective cohort study. ⋯ 4.

A cross-sectional study. ⋯ The spinal cord diameter was independent of the spinal canal diameter and the relative size of a spinal cord and spinal canal differed on an individual basis. In addition, the ratio of spinal cord/dural sac in subjects with SCC was significantly larger. Therefore, a relatively large spinal cord could be a risk factor for SCC.
