Observational Study
Intraoperative Surgeon Assessment of Bone: Correlation to Bone Mineral Density, CT Hounsfield units and Vertebral Bone Quality.
Retrospective observational study of consecutive patients. ⋯ Spine surgeons' qualitative intraoperative assessment of bone correlates with preoperative radiologic parameters, particularly in posterior thoracolumbar surgeries. This information is valuable to surgeons as this supports the idea that decisions based on feel in surgery have a statistical foundation.

Observational Study
Epidemiology of Schmorl's Node in the Thoracic Spine: A Subtype Analysis.
Retrospective observational study. ⋯ The clinical characteristics of SN differ based on the developmental and acquired subtypes, including the relationship with age, gender, and BMD. The subtypes may be considered distinct clinical entities as a result.

A retrospective clinical study with confirmatory evaluation in healthy volunteers. ⋯ 3.

Cadaveric study. ⋯ Our cadaveric study demonstrates that an adequately performed E-TLIF discectomy may be comparable to a T-TLIF discectomy. Further research is required to maximize the efficiency and instrumentation of this technique.

Retrospective study. ⋯ The authors found that NR-NF was the most common type of failure following surgery for atlantoaxial dislocation. Revision strategies can be guided according to the descriptive classification of failure, and revision surgery should focus on achieving adequate reduction, appropriate fixation, and reliable fusion to optimize postsurgical outcomes.
