Comparative Study
Lumbar modic changes-a comparison between findings at low- and high-field magnetic resonance imaging.
A cross-sectional observational study. ⋯ There was a significant difference between low- and high-field MRI regarding the overall prevalence of any Modic change, but this had opposite directions for types 1 and 2: type 2 dominated in high field and conversely in high field [corrected]. The type of MRI unit should be taken into consideration when diagnosing patients with Modic changes

A longitudinal case study. ⋯ Pedicle screw instrumentation performed before the age of 5 years does not cause a negative effect on the growth of pedicles, the transverse plane of the vertebral body, or the spinal canal. It can be safely performed in the treatment of deformity in this age group.

Retrospective cohort study. ⋯ Clinical outcomes of cervical arthroplasty in multilevel spondylosis are similar to single-level outcomes. However, the significantly higher rate of HO found in multilevel arthroplasty and its long-term effect warrant further investigation.

A retrospective cohort analysis. ⋯ BAs prevented the development of de novo cervical spine lesions in patients with RA, but failed to inhibit progression of pre-existing RA lesions.
