Comparative Study
In vivo topographic analysis of lumbar facet joint space width distribution in healthy and symptomatic subjects.
In vivo 3-dimensional facet joint space width measurement. ⋯ This in vivo study shows variations in facet joint space width narrowing with spinal level and region within the facet joint and in vivo evidence of localized, age-influenced facet cartilage thinning. Techniques developed in this study may be applied in the detection of early osteoarthritis-related changes in the facet joints.

Follow-up study. ⋯ The results suggest that neither isometric neck muscle strength nor passive mobility of cervical spine has predictive value for later occurrences of neck pain in pain-free working-age women. Thus, screening healthy subjects for weaker neck muscle strength or decreased mobility of the cervical spine may not be recommended for preventive purposes.

Observational cross-sectional study. ⋯ Outcome for patients diagnosed with PMASC remains poor and presents an ongoing challenge for professionals in the field of neurospinal medicine and surgery. In our analyses of AA, adult patients, males, and patients undergoing radical resections were associated with increased survival. However, incidence of these lesions is low; hence, building strong collaborative, interdisciplinary, and multi-institutional study groups is necessary to define the optimal treatment of PMASC.

A biomechanical analysis of soft-tissue restraints to passive motion in odontoid fractures. ⋯ This study identifies that type II odontoid fractures without associated soft-tissue injury may be stable under certain loading modes.

Multicenter Study Comparative Study
Scoliosis Research Society-Schwab adult spinal deformity classification: a validation study.
Inter- and intra-rater variability study. ⋯ Data from this study show that there is excellent inter- and intra-rater reliability and inter-rater agreement for curve type and each modifier. The high degree of reliability demonstrates that applying the classification system is easy and consistent.
