Small language models: The big play for agentic artificial intelligence in orthopaedics.

Abstract

While the integration of artificial intelligence in orthopedics is accelerating, the focus has largely been on powerful but resource-intensive Large Language Models (LLMs). This editorial argues for a strategic shift towards Small Language Models (SLMs) for many specialized clinical applications. SLMs offer a more efficient, cost-effective, and adaptable solution for the narrowly-scoped tasks common in orthopedics. We discuss their potential in surgical assistance, personalized patient management, and administrative automation, positing that the future of practical AI in our field lies in a diverse ecosystem of specialized SLMs. However, we also underscore that rigorous validation and the development of robust evaluation benchmarks are critical to ensure their safe and trustworthy integration into clinical practice.
