A retrospective case series. ⋯ The authors describe a novel classification system that is of practical use for planning the complete resection of cervical dumbbell tumors.

Retrospective. ⋯ Inflammatory findings, such as facet joint effusion, bone marrow edema, and soft tissue edema, are not commonly identified in radiology reports. Further investigations are needed to determine the clinical importance of MRI-detected lumbar facet joint inflammatory features as a potential mechanism of nociception and as a predictor of outcomes following injections or other therapies.

This was a retrospective study with prospective patient contact attempted to collect current data. ⋯ In this large consecutive series, 1.26% of TDRs were removed/revised. The low rate over a 20 year period supports the safety of these devices.

Retrospective cohort. ⋯ The ODI is a valid measure of disability as measured by pain and function in patients with ASD. It is responsive to change in a manner not different from validated PROMIS-CAT or the SRS-22r legacy measure. It is multidimensional, however, as it assesses both pain and function simultaneously. It does not measure disability related to self-image and may not account for all disease-related disability in patients with ASD.

Prospective case-control study. ⋯ BTK expression was higher in PBMCs from patients with AS when compared with controls, and was associated with a higher disease activity index, inflammatory reactants, and arthritis and extra-articular manifestations. These findings suggest that BTK expression may play a crucial role in the inflammatory process in individuals with AS.
