Prevalence of degenerative imaging findings in lumbar magnetic resonance imaging among young adults.
A cross-sectional imaging study of young adults. ⋯ Almost half of young Finnish adult aged 21 years had at least one degenerated disc, and a quarter had a bulging disc. Modic changes and disc herniations were, however, relatively rare.

Cross-sectional study. ⋯ The current study confirms a significant association between sagittal orientation and OA of the lumbar facet joints at L4-L5 and DS. Facet tropism was not associated with occurrence of facet joint OA or DS. Additional, longitudinal studies are needed to understand the causal relationship between facet joint morphology and OA.

Retrospective review. ⋯ Growing rods can include pelvic fixation to correct pelvic obliquity or obtain adequate fixation. Dual iliac fixation provides the best correction. Both iliac screws and rods provide satisfactory distal fixation; iliac screws had a higher rate of breakage. Growing rods with pelvic fixation are effective in deformity correction and achieving growth.

Clinical Trial
Pediatric and adult three-dimensional cervical spine kinematics: effect of age and sex through overall motion.
Cross-sectional study. ⋯ HAM location in axial rotation and flexion/extension was more anterior in young females compared to adult females. Young females had a more anterior HAM location in flexion/extension compared to young males, indicating an effect of sex. For females, the HAM locations of adults were superior to those of children in flexion/extension and lateral bending whereas in males the HAM locations of adults were inferior to those of children. Age-related differences in HAM orientation were also observed in axial rotation and lateral bending. CONCLUSION.: Cervical spine kinematics vary with age and sex. The variation in spine mechanics based on age and sex found in the present study may indicate general trends that would grow stronger in even younger children (age <4 years).
