Surgical invasiveness, reoperation, and preoperative depression are predictive of super-utilization in adult spinal deformity surgery.

Purpose: A subset of adult spinal deformity (ASD) patients undergoing corrective surgery receive a disproportionate level of medical resources and incur greater costs. We examined the characteristics of such super-utilizers of health care resources among ASD patients.

Methods: This prospective, multicenter study analyzed data from ASD patients with > 4 levels of spinal fusion and a minimum 2-year follow-up.

Listhesis and Spinopelvic Inclination of Upper Instrumented Vertebra Region and the Implications on Proximal Junctional Kyphosis.

Study Design: Retrospective analysis of prospective data.

Objective: Evaluate the impact of radiographic and morphologic configuration of the uppermost instrumented vertebrae (UIV) region on proximal junctional kyphosis (PJK) rates.

Background: Literature is limited on evaluation of the preoperative landing zone (UIV-1 to UIV +2 levels) and its impact on development of PJK.

Prompt Engineering and Follow-Up Questioning Improves the Readability of Spine Surgery Questions in Large Language Models.

Introduction: The field of spine surgery is complex, and patient education material within the field are often written at a reading level that exceeds the recommended standard. Large language models (LLMs), such as ChatGPT, have shown potential for generating educational content, but require further investigation regarding readability and adaptability in responding to follow-up questions. The purpose of this study is to evaluate which model and prompting strategies improve the readability the most, especially in newer models.

Re-Epithelialisation in a Yorkshire Pig Full-Thickness Excisional Wound Model Is Associated With Keratinocyte Activation, Oxidative Stress, and Biomacromolecule Oxidation.

Pig skin represents the best analogue for human skin both anatomically and physiologically, with this model used extensively for pre-clinical testing of therapeutics and biomaterials. However, the molecular processes underlying re-epithelialisation in pigs are still not well described compared to murine models. Our objective was to characterise the re-epithelialisation process in porcine full-thickness excisional wounds in Yorkshire pigs.

The Inter-Tester and Test-Retest Reliability of the Off-Field SCAT6 Assessment Tool In An Adult Population.

Objective: No previously published repeatability and reliability data for The Sports Concussion Assessment Tool-6 (SCAT6) exists. We aimed to evaluate inter/intra-tester reliability of the off-field SCAT6 in a non-concussed adult population.

Design: Inter-rater and Intra-rater reliability study design.
