Alfred Philip Yoon, M.D.

About

Alfred Philip Yoon, M.D. is an Assistant Professor specializing in Hand Surgery, Plastic Surgery, and Reconstructive Surgery at UC Davis Health. He is a fellowship-trained hand and upper extremity surgeon with expertise in peripheral nerve surgery, brachial plexus surgery, spasticity surgery, and general hand conditions such as bone, tendon, and ligament reconstruction. His clinical philosophy emphasizes patient-centered care, aiming to help patients regain functional independence after hand injuries or conditions through individualized treatment plans and high-quality care. Dr. Yoon's research focuses on solving problems in musculoskeletal medicine with artificial intelligence, including detecting fractures not visible on X-rays using neural networks. He has published extensively on topics such as outcomes after surgical interventions for Dupuytren's disease, distal radius fractures, digit replantation, and scaphoid fractures. His work also explores cost-effective treatments in hand surgery and improving surgical outcomes through precision medicine and statistical learning. His academic background includes a B.S. in Bioengineering from UC Berkeley, an M.D. from UCLA's David Geffen School of Medicine, and a fellowship at the Mayo Clinic Department of Orthopedic Surgery. He is board-certified by the American Board of Plastic Surgery and actively participates in professional societies such as the American Association for Hand Surgery and the American Society for Surgery of the…

  Importance: Replantation and revascularization are among the most technically challenging surgical procedures and have varying success rates. Methods to assess surgeon skill for this complex undertaking are lacking. Objective: To examine whether a surgeon proficiency score is associated with clinical outcomes across multiple institutions. Design, Setting, and Participants: This multicenter retrospective cohort study analyzed all digit replantation and revascularization after traumatic amputation…

• Effects of Image Degradation on Deep Neural Network Classification of Scaphoid Fracture Radiographs: Comparison Study of Different Noise Types

  JMIR Medical Informatics · 2025-12-08

  articleOpen access

  Background: Deep learning models have shown strong potential for automated fracture detection in medical images. However, their robustness under varying image quality remains uncertain, particularly for small and subtle fractures, such as scaphoid fractures. Understanding how different types of image perturbations affect model performance is crucial for ensuring reliable deployment in clinical practice. Objective: This study aimed to evaluate the robustness of a deep learning model trained to de…

• Revision Thumb CMC Arthroplasty: Risk Factors and Healthcare Economic Implications

  Plastic & Reconstructive Surgery · 2025-11-10

  article1st authorCorresponding

  BACKGROUND: The risk factors as well as financial implications of revision thumb carpometacarpal joint(CMC) arthroplasty are unclear. We aimed to identify risk factors for revision thumb CMC surgery and how it impacts healthcare cost and utilization. METHODS: We conducted a retrospective longitudinal analysis using a nationwide claims database, Optum's de-identified Clinformatics® Data Mart, between October 1st, 2015 and December 31st, 2018. Healthcare utilization and costs were measured from 1…
