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.

Prospective study. ⋯ We hypothesized that kyphotic alignment change by posterior structural injury after cervical laminoplasty would be more marked in patients with high T1 slope, and demonstrated that patients with cervical myelopathy with high T1 slope had more kyphotic alignment changes after cervical laminoplasty at 2-year follow-up.

A retrospective cohort study of 2321 patients consecutively admitted to one center and diagnosed with acute symptoms of metastatic spinal cord compression (MSCC). ⋯ Patients with MSCC from pulmonary and renal cancers experienced improved survival in the study period. No improvement was seen for patients with other oncological diagnoses. This corresponds to reports from oncological studies and could affect preoperative scoring systems.
