Large language models in the vertical integration of spine surgery workflow: a scoping review
Abstract
PURPOSE: To evaluate current evidence regarding the clinical reliability and reasoning capabilities of Large Language Models (LLMs) and Multimodal Large Language Models (MLLMs) within the spine surgery workflow. This scoping review utilizes a novel Vertical Integration Maturity Scale (VIMS) to map model maturity across five stages of the vertical workflow, identifying persistent research gaps and technical prerequisites for clinical implementation.
METHODS: A systematic search was conducted across PubMed, Embase, and Scopus for peer-reviewed studies published between January 2023 and January 2026. Utilizing the Population, Concept, and Context (PCC) framework, studies were selected based on their application of generative AI to the clinical evaluation and surgical management of spinal pathologies. Data were analyzed via independent dual-coding using a two-dimensional framework mapping five VIMS levels across five functional workflow stages. Synthesis included categorization by model architecture, input modality, and performance benchmarks, with inter-rater reliability calculated to validate the novel framework.
RESULTS: Of 351 identified records, 40 studies met the inclusion criteria. Research density peaked in Stage III (Evaluative Decision Logic) at VIMS Level 1 (n = 15), indicating a methodological focus on evidence-based guideline retrieval over patient-specific synthesis. While ChatGPT-4 showed high concordance (61.1% to 88.2%) with clinical guidelines, diagnostic…
