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.

Observational Study
Ten-Year Outcomes of Minimally Invasive Versus Open Transforaminal Lumbar Interbody Fusion in Patients With Single-Level Lumbar Spondylolisthesis.
A retrospective observational study. ⋯ Efficacy of MI-TLIF for patients with single-level lumbar spondylolisthesis is comparable to that of open TLIF over 10-years. However, MI-TLIF may have superior perioperative recovery and 2-year postoperative functional outcomes than open TLIF.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.

Basic science, experimental animal study. ⋯ Injection of BTX-A into the paraspinal rabbit muscles leads to significant alterations in the contractile properties of fast, but not slow, fibers.Level of Evidence: N/A.

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.
