A prospective cohort study. ⋯ As hypothesized, for convergent validity the PROMIS-PF4 has stronger correlation with the RMDQ than the NPRS and good discriminative validity for identifying patients with pain-related disability and at high risk of persisting disability but not for identifying pain intensity or low-risk of persisting disability. Consequently, the PROMIS-PF4 has adequate construct validity for measuring pain-related disability in an LBP population in chiropractic care.

Retrospective review. ⋯ Compared with patients with successful pelvic compensation, those with failed pelvic compensation showed lower postoperative improvements in clinical and radiographic outcomes. Therefore, it is important to consider pelvic compensation when planning surgical correction of deformities. Distinct surgical approaches, including overcorrection of the PI-lumbar lordosis mismatch or global sagittal alignment, should be attempted to ensure postoperative symptom improvement.

A retrospective review. ⋯ Choosing minimally rotated (Gd 0/1) TV on prone XR saves levels without sacrificing radiographic outcomes.

Cross-sectional study. ⋯ This is the first study to create a PROM addressing the functional impact of cervical stiffness following surgical arthrodesis. The CSRS-CSDI was a reliable and valid measure of postoperative stiffness impact on patient function. This may prove useful in counseling patients regarding their expected outcomes with further investigation demonstrating its value in a prospective fashion.
