A multidisciplinary group led by Jian Song at Shanghai Jiao Tong University’s Xinhua Hospital integrates machine learning algorithms and surgical robotics to advance orthopedic practice. They develop convolutional neural networks for automated imaging analysis—such as cartilage and fracture segmentation—and deploy AI-driven navigation systems to optimize joint replacements and ligament reconstructions, aiming to reduce diagnostic errors and improve patient outcomes in musculoskeletal care.

Key points

• U-Net and SegResNet CNNs achieve 0.77–0.88 Dice scores for cartilage and meniscus segmentation in MRI within under 5 s per scan.
• Deep convolutional neural networks detect humerus, wrist, rib, and spinal fractures with over 90% accuracy, matching expert radiologists.
• AI-driven ROSA® and Mako® robotic systems deliver sub-millimeter implant alignment and optimized soft-tissue balancing in arthroplasties.

Why it matters: By integrating deep learning imaging with robotic-assisted surgery, this approach markedly enhances diagnostic accuracy and patient-specific treatment, reducing complications.

A 2025 review by Military Medical Research details advancements in EEG-based BCIs. The study explores innovative methods, such as artifact removal and deep learning, enhancing applications in epilepsy detection and stroke rehabilitation. This work illustrates practical examples of how neurotechnology is reshaping patient care and therapeutic interventions.
