Hong Kong varsity introduces robot-assisted spine surgery

HONG KONG: In a groundbreaking development, the Department of Orthopaedics and Traumatology at the University of Hong Kong (HKUMed) has introduced robot-assisted technology in spine surgery, pledging unprecedented precision and safety in spinal procedures.

Led by Dr. Kenny Kwan Yat-hong, Clinical Associate Professor and Chief of the Division of Spine Surgery, and Prof Jason Cheung Pui-yin, Clinical Professor and Chairperson of the Department of Orthopaedics and Traumatology, the research team has successfully performed robot-guided spinal procedures on 20 patients since October 2023.

The team collaborated with Queen Mary Hospital and Duchess of Kent Children's Hospital, showcasing the immense potential of robotic technology in revolutionizing spinal surgery.

Spinal fusion surgery, especially for conditions like scoliosis and other spine deformities, traditionally relies on freehand techniques, which, while effective, may not always ensure perfect accuracy in screw placement. The introduction of robot-assisted technology transforms this scenario by offering unparalleled precision for each patient’s unique anatomy.

"This innovative technology empowers surgeons to deliver the best possible outcomes for their patients when performing complex spinal procedures," says Dr. Kenny Kwan Yat-hong. "We believe this revolutionary approach is a game-changer for local patients with scoliosis or other spinal problems."

Prof Jason Cheung Pui-yin echoed this sentiment, stating, "The enhanced precision and predictability of robot-assisted spine surgery mean that we can provide our patients with safer, more effective treatments, leading to faster recovery and better long-term outcomes."

The robotic system allows for preoperative planning incorporating CT images of the patient’s spine, enabling surgeons to determine the ideal entry point, screw size, and trajectory for each patient. During surgery, the robotic arm precisely guides the placement of implants, providing real-time images of the patient’s spine and ensuring unparalleled accuracy and safety.

The launch of this novel technology in public hospitals in Hong Kong will help expand the scope of spinal surgery in the city. The research team anticipates further applications of robotic systems in spinal surgery, promising shorter operation times, reduced waiting lists, and ultimately, improved patient outcomes.
