Inspired by bionic principles, Sir Run Run Shaw Hospital, affiliated with the Medical School of Zhejiang University in Hangzhou, has developed a bone glue material that can achieve immediate and strong adhesion within the human blood environment, bringing a new treatment method for patients with comminuted fractures — a bone broken in at least two places.

Metal internal fixators such as screws and steel plates are mainly used to treat fractures in clinics. The traditional process of fixing small bone fragments is not only time-consuming and labor-intensive, but also easily leads to the loss or absorption of bone fragments during surgery, ultimately delaying bone healing.The bone glue, Gu 02, has a maximum bonding strength of over 200 kilograms, and can be naturally degraded and absorbed six months after surgery. The material is injected through a 2-3 centimeter minimally invasive incision, and the fixation of comminuted bones can be completed within three minutes, covering fracture repair in every part of the body. It has already proved safe and effective in more than 150 patients.
