The objective of this systematic review is to present a comprehensive summary of existing research on the use of 3D printing in spinal surgery. ⋯ 3D printing in spine surgery, a rapidly growing area of research, is predominantly used for creating drill guides for screw insertion, anatomical models, and innovative implants, enhancing clinical outcomes and reducing operative time. While cost-efficiency remains uncertain due to insufficient data, some 3D printing applications, like pedicle screw drill guides, are already widely accepted and routinely used in hospitals.

No studies have explored the reliability of the Rigo classification system using surface topography (ST), which would allow optimization without radiation exposure. This study aims to measure and compare the intra- and inter-observer reliability (Kappa values) and accuracy of the Rigo system between ST and X-ray for overall types and subtypes. ⋯ ST-based Rigo system demonstrates very good intra-rater reproducibility and moderately good inter-rater reproducibility. Surface topography is comparable to X-ray for the Rigo system, and therefore can be considered a reliable alternative in clinical application.

The purpose of this study was to investigate threshold values for classifying bone as normal or osteoporotic based on Computed Tomography (CT) Hounsfield Units (HU) and to determine if clinically applicable values could be derived to aid spine surgeons evaluating bone quality using CT. ⋯ There is variation in HU values used to differentiate normal from compromised bone quality, even after limiting studies. For patients with HU values between or near 170 or 115 HU, a DEXA scan may be warranted for further evaluation. With ongoing investigation in this area, threshold values for classifying bone quality using CT will be continually refined.

An atypical presentation of cervical spondylopathy (CS), trigeminal neuralgia (TN) is attributable to the extension of trigeminal nuclei into the spinal cord and is frequently overlooked, leading to limited discussion with patients regarding potential anterior cervical surgery. Our systematic review assesses the effectiveness of cervical surgery for concurrent trigeminal neuralgia in cases of cervical spondylopathy. ⋯ Besides common manifestations, high cervical stenosis can cause trigeminal neuralgia. This case report and systematic review confirms spinal decompression and fusion surgery may be effective in select cases. Surgeons should raise the possibility of cervical spine involvement when counseling patients with this disease.

To translate and culturally adapt the Core Outcome Measures Index for the back (COMI-back) into Thai and to evaluate its psychometric properties in Thai-speaking patients with low back pain (LBP). ⋯ The Thai COMI-Back shows strong psychometric properties, making it suitable for clinical and research use in Thailand.
