Observational Study
Racial and Social Determinants of Health Disparities in Spine Surgery Affect Preoperative Morbidity and Postoperative Patient Reported Outcomes: Retrospective Observational Study.
Retrospective observational study. ⋯ Racial and socioeconomic disparities in patients' preoperative physical and mental health at presentation for spine surgery are associated adversely with postoperative outcomes. Renewed focus on structural factors influencing preoperative presentation, including timeliness of care, is essential.Level of Evidence: 3.

A biomechanical in vitro investigation. ⋯ We designed a BAAOJ for correcting atlantoaxial disorders arising from atlantoaxial instability. As a non-fusion device, the most critical feature of BAAOJ replacement is the retention of flexion-extension, lateral bending, and axial rotation range of motion similar to the normal state. It can also stabilize the atlantoaxial complex, and the BAAOJ itself has a good initial stability.Level of Evidence: 4.

Retrospective descriptive study. ⋯ Although case rates decreased, patient harm was attributable to health care in the majority of recently closed cases. Therefore, crucial opportunities remain to enhance patient safety in spine surgery.Level of Evidence: 4.

Retrospective cohort study. ⋯ Our data suggest that although several key parameters are maintained over time out to 2years postopera- tively, TK tends to worsen over time for all patients, whereas TLK preferentially increases in the LT group. Nevertheless, despite these trends, compensatory changes are seen in PT such that global alignment is relatively maintained.Level of Evidence: 3.

Observational and morphological study with three-dimensional (3D) computed tomography (CT) analysis. ⋯ For HFM children, the incidence of C1 deformation increased from type I to type Ill. The probability of C2 anomaly and C1-C2 instability in children with different types of HFM is nearly the same. The craniovertebral junction of every HFM child must be monitored carefully for C1-C2 instability before any surgical procedure to avoid atlantoaxial dislocation and spinal cord injury.Level of Evidence: N/A.
