Multicenter Study
Vertebral artery injury associated with blunt cervical spine trauma: a multivariate regression analysis.
Retrospective analysis of prospective registry data. ⋯ VAI associated with blunt cervical spine injury is a marker for more severely injured patients. High-risk patients with basilar skull fractures, occipitocervical dissociation, fracture displacement into the transverse foramen more than 1 mm, ankylosing spondylitis/diffuse idiopathic skeletal hyperosteosis, and facet subluxation/dislocation deserve focused consideration for VAI screening.

Multicenter Study
Clinically significant differences exist between curves in operative idiopathic early-onset scoliosis and adolescent idiopathic scoliosis.
Retrospective analysis. ⋯ Significant radiographical differences exist between operative IEOS and AIS curves. IEOS curves are greater in magnitude, more kyphotic, less well compensated, and have a more caudal apex and stable vertebra. These findings suggest that younger patients may require more distal instrumentation and that proximal fixation techniques should consider the additional pullout forces created by the greater kyphosis.

Prospective in vivo radiation exposure study. ⋯ Prolonged exposure to "low-level" radiation as an occupational risk remains a concern for medical personnel. Radiation exposures to unprotected, radiosensitive locations, such as the axilla or eye, are worrisome. However, following radiation safety guidelines, 2700 LLIF procedures can be performed per year before exceeding occupational dose limits. Adherence to radiation safety guidelines is necessary to avoid sequelae related to an invisible but potentially deadly risk of minimally invasive spine surgery procedures.

Clinical Trial
Specific neck training induces sustained corticomotor hyperexcitability as assessed by motor evoked potentials.
Experimental investigation of short-term and long-term corticomotor effects of specific neck training, coordination training, and no training. ⋯ Specific neck training induced a sustained hyperexcitability of motor neurons controlling the neck muscles compared with coordination training and controls. These findings may prove valuable in the process of developing more effective clinical training programs for unspecific neck pain.

Cohort study. ⋯ Meaningful classifications exist for sagittal plane posture in young adolescent boys, both on gross body segment and lumbopelvic level. In terms of clinical importance, that is, low back pain and neck pain prevalence, postural subgrouping strategies based on the orientation of gross body segments are suggested to be superior when compared with lumbopelvic grading.
