Current applications and challenges of artificial intelligence in orthopedic imaging: A narrative review.

BackgroundArtificial intelligence (AI), especially machine and deep learning, is an emerging tool in medicine with growing applications in orthopedic imaging. Given imaging's central role in diagnosis, surgical planning, and treatment monitoring, this narrative review maps the current and potential uses of AI in orthopedics, identifies underdevelopment sections, and emphasizes limitations in clinical practice.MethodsA PubMed search used the terms "Orthopedic," "Imaging," and "Artificial Intelligence." Studies were screened by title and abstract, excluding non-orthopedic or non-AI studies, animal research, pediatric populations, and robotics or pharmacology papers. Eighty-five peer-reviewed articles were analyzed for imaging modality, clinical application, AI technique, and assigned a level of evidence. They were selected based on relevance to AI in orthopedic imaging.ResultsAI applications spanned radiography, CT, MRI, DTI, and ultrasound. For bone pathology, AI aided fracture detection and osteoarthritis prediction with clinician-level accuracy. In soft tissue injuries, models assisted in rotator cuff and meniscus tear detection and muscle segmentation. AI-driven 3D reconstructions and virtual reduction models enhanced surgical planning, particularly in joint replacement and trauma. Spine imaging benefited from vertebral segmentation, disc degeneration classification, and paraspinal muscle analysis, improving preoperative planning and outcome prediction. radiography, CT, MRI, DTI, and ultrasound. An important distinction is that many of these models generated outputs that surrounded conditional probabilities rather than categorical diagnoses. Many pitfalls remain including single-center overfitting, data leakage, and inter-reader variability.ConclusionsAI demonstrates potential to enhance diagnostic accuracy, streamline surgical planning, and improve workflow efficiency. Challenges remain, including data bias, regulatory constraints, and ethical considerations, warranting caution to its blanket application in medicine. Continued integration and validation are needed for optimal clinical use.Clinical RelevanceAI may serve as an adjunct to clinicians, supporting imaging interpretation and surgical decision-making while preserving human judgment.
