Retrospective single-center imaging-based case-control study. ⋯ A substantial association between C5 foraminal stenosis and ipsilateral frozen shoulder was found. C5 radiculopathy could be a risk factor for "neurogenic frozen shoulder". Those diagnosing frozen shoulder and cervicobrachialgia should recognize that frozen shoulder and C5 radiculopathy may coexist. A multidisciplinary approach involving both shoulder and spine specialists is recommended for a definitive diagnosis.

Retrospective case series. ⋯ ATR and AVR demonstrated significant axial plane correction at two-years postoperative in patients undergoing PSF for AIS. BSR did not maintain significant improvement by the two-year visit.

Retrospective review of a prospective multicenter adult spinal deformity (ASD) study. ⋯ Level III-prognostic.

Retrospective review of prospectively collected data. ⋯ This work proposes new insights into the complex interaction between sagittal alignment and cervical paraspinal muscles by emphasizing the importance of these muscles in sagittal alignment. The authors hypothesize that with cervical degeneration, the stabilizing function of the anterior muscles decreases, which may result in an increase in the compensatory mechanism of the PL muscles. Consequently, there may be a corresponding increase in the C2 to C7 SVA and a larger C2 slope.

Comparative analysis. ⋯ ChatGPT was able to produce a sufficient clinical guideline recommendation for low back pain, with overall improvements if initially prompted. However, it tended to wrongly suggest evidence and often failed to mention, especially postprompt, when there is not enough evidence to adequately give an accurate recommendation.
