Randomized Controlled Trial
Effect of Topical Steroid on Swallowing following ACDF: Results of a Prospective Double-Blind Randomized Control Trial.
Randomized, double-blinded, controlled trial. ⋯ Local administration of corticosteroid after multilevel ACDF can decrease postoperative severity and symptomatology of dysphagia during the immediate postoperative period to 1-month postoperatively. The long-term effects of local steroid administration on fusion and other complications will need to be established in future studies.Level of Evidence: 1.

Kinematics of the cervical spine was investigated using cone beam computed tomography (CBCT) images combined with three dimensions to three dimensions (3D-3D) registration technology in patients after anterior odontoid screw fixation (AOSF) surgery. ⋯ Although AOSF surgery reduced the flexion-extension ROMs of all investigated spinal segments, additionally, it reduced twisting ROMs of C1-C2 and C1-C7, but only lateral bending ROM of C2-C3, when compared with the control group. The data implied that the AOSF surgery would result in different biomechanics changes in the atlantoaxial segment and caudal adjacent segment. Longer-term follow-up studies of larger patient cohorts are necessary to evaluate the clinical outcomes of patients after the AOSF surgery.Level of Evidence: 3.

Prospective cross-sectional study. ⋯ The AIS cohort in our study demonstrated lower levels of eating psychopathology than healthy controls. Surprisingly, eating behavior does not seem to be affected by orthotic management. However, quality of life and self-body image could be impaired in scoliotic girls, especially when they practice physiotherapy exercises, whereas those who practice sport seem to be preserved in this regard.Level of Evidence: 4.

An ex vivo study of the rabbit's vertebral endplate. ⋯ The regulation of vascular buds and VEGF expression in the VEP represents one of the mechanisms of axial distraction and dynamic loading.Level of Evidence: N/A.

Population-based birth cohort study. ⋯ Vertebral height was associated with the presence of MC2. Further studies are needed to clarify the role of vertebral dimensions as independent risk factors for MC.Level of Evidence: 3.
