From Oysters to Orthopedics: China’s “Bone-02” Bio-Glue Redefines Fracture Repair

Researchers at Zhejiang University’s Sir Run Run Shaw Hospital have unveiled Bone-02, a biomimetic “bone glue” capable of repairing complex fractures in just three minutes. The innovation was inspired by oysters’ remarkable ability to adhere to rocks underwater — a challenge long considered impossible to replicate in human physiology.

How it works

Unlike metal plates or screws, Bone-02 is a biocompatible adhesive that bonds bone fragments directly — even in moist, blood-rich surgical fields where traditional materials fail. The procedure requires only a 2–3 cm incision and a single injection; the glue sets within minutes, providing stable fixation without the trauma of open surgery.

Clinical evidence and performance

In over 150 treated patients, Bone-02 achieved full healing without complications or secondary procedures. Laboratory tests confirmed a bonding strength exceeding 400 lb, shear 0.5 MPa, and compressive 10 MPa — comparable to standard orthopedic fixation systems. Because the material is biodegradable, it is gradually absorbed as bone regenerates, eliminating the need for implant removal.

Why it matters for clinical research

For decades, scientists sought a true “bone glue” that could function safely inside the body — combining high adhesion, biocompatibility, and mechanical strength. Bone-02 is the first material to show these properties in human clinical settings, bridging materials science and regenerative medicine. If larger trials confirm durability, this approach could transform orthopedic surgery, reducing infection risks, recovery times, and healthcare costs.

The road ahead

The Bone-02 project still requires robust clinical validation through multicenter, randomized trials to verify long-term safety, strength, and integration with bone tissue. Yet its early results already signal a shift toward bio-inspired, minimally invasive, and regenerative orthopedics — an area that will demand new clinical trial designs, interdisciplinary expertise, and regulatory frameworks.

At Cromos Pharma, we see such innovations as reminders that clinical research is not just about testing drugs — it’s about transforming how science heals. From oyster shells to human bones, nature continues to inspire breakthroughs that redefine what medicine can do.
