Multicenter Study Observational Study
The Utility of Transcranial Stimulated Motor-evoked Potential Alerts in Cervical Spine Surgery Varies Based on Preoperative Motor Status.
A prospective multicenter observational study. ⋯ The utility of Tc-MEP in patients with a preoperative severe motor status was enhanced, even in those without high-risk spine surgery. Regardless of the motor status, appropriate interventions following Tc-MEP alerts may prevent postoperative paralysis.

A descriptive epidemiologic study. ⋯ Lumbosacral transforaminal and interlaminar/caudal spinal epidural injections were shown to decrease by 52.37% per 100,000 patients from 2010 to 2019. Changing demographics of those undergoing such injections and practice patterns are important to consider in the picture of overall spine service utilization. Variations in injection utilization trends by patient insurance raise questions regarding disparities in care.

Randomized Controlled Trial
Assessment of Fusion after Anterior Cervical Discectomy and Fusion Using Convolutional Neural Network Algorithm.
A convolutional neural network (CNN) is a deep learning (DL) model specialized for image processing, analysis, and classification. ⋯ The CNN algorithm for fusion assessment after ACDF trained using lateral cervical radiographs showed a relatively high diagnostic accuracy of 89.5% and is expected to be a useful aid in detecting pseudarthrosis.

This was a preclinical study. ⋯ This study demonstrates sex-dependent differences in bone regeneration induced by rhBMP-2. Further investigation is needed to uncover the extent of and mechanisms underlying these sex differences, particularly at different doses of rhBMP-2.
