We investigated whether a high Body Mass Index (BMI) affects the outcomes following Minimally Invasive TLIF (MI-TLIF) for degenerative lumbar pathologies. ⋯ In patients treated by MI-TLIF for degenerative lumbar spine pathology, BMI is not a factor that negatively affects the functional and clinical outcomes.

Multiple solutions for navigation-guided pedicle screw placement are available. However, the efficiency with regard to clinical and resource implications has not yet been analyzed. The present study's aim was to analyze whether an operating room sliding gantry CT (ORCT)-based approach for spinal instrumentation is more efficient than a mobile cone-beam CT (CBCT)-based approach. ⋯ The choice of imaging technology for navigated pedicle screw placement has significant impact on standard spine procedures even in a high-volume spine center with daily routine in such devices. Particularly with regard to the duration of surgeries, the shorter time needed for preparation and de-positioning in the ORCT group made the main difference, while the accuracy was even higher for the ORCT.

Augmented reality (AR) is an emerging technology with great potential for surgical navigation through its ability to provide 3D holographic projection of otherwise hidden anatomical information. This pilot cadaver study investigated the feasibility and accuracy of one of the first holographic navigation techniques for lumbar pedicle screw placement. ⋯ This pilot study demonstrates improved angular precision in one of the first AR-navigated pedicle screw placement studies worldwide. Technical shortcomings need to be eliminated before potential clinical applications.

To assess test-retest reliability, internal consistency, construct validity, and the presence of ceiling and floor effects in the Brazilian version of the Short-Form Neck Disability Index (SF-NDI) in patients with chronic neck pain. ⋯ SF-NDI with 5 items has adequate measurement properties in Brazilian chronic neck pain patients.

This study systematically analyzed and assessed the interrelationships among vertebral anomaly location, congenital scoliosis (CS) type and associated abnormality prevalence. ⋯ Cervical malformations had higher prevalence of mixed defects, musculoskeletal and intraspinal defects and multi-region involved. Thoracic malformations had higher prevalence of intraspinal and musculoskeletal defects and more involvement of only one vertebral region. Lumbar vertebral malformation patients had much lower prevalence of intraspinal and musculoskeletal defects and more involvement of only one vertebral region. Cervical malformation was a risk factor for more associated anomalies and more severe vertebral anomalies, which deserves more attention from surgeons in outpatient clinic.
