Researchers Develop "Glue Gun" for Direct Bone Grafting, Revolutionizing Fracture Repair

Scientists Develop 'Glue Gun' for Direct Bone Grafting A team of researchers from Sungkyunkwan University in South Korea has successfully modified a standard glue gun to 3D print a bone-like material directly onto fractures, paving the way for its use in operating rooms. The innovative device, which has been tested on rabbits, shows promise in fixing irregularly shaped fractures during surgery. According to Jung Seung Lee, co-author of the study and biomedical engineer at Sungkyunkwan University, "To my knowledge, there are virtually no previous examples of applying this technology directly as a bone substitute." This makes the approach unique and sets it apart from conventional methods. The researchers believe that their device could be particularly useful in situations where traditional bone grafting techniques are not feasible. The modified glue gun uses a combination of 3D printing and biomaterials to create a bone-like material that can be applied directly onto fractures. This eliminates the need for multiple surgeries and reduces recovery time for patients. The researchers have successfully tested the device on rabbits, but further studies in larger animal models are needed before it can be used on humans. The development of this technology has significant implications for the field of orthopedic surgery. Conventional bone grafting techniques often require multiple surgeries and can lead to complications such as infection or rejection. The use of a 3D printed bone substitute could reduce these risks and improve patient outcomes. Lee noted that "further studies in larger animal models are needed before the technology can be used on humans." However, if successful, this technology could revolutionize the way surgeons approach complex fractures. The researchers plan to continue testing the device and refining its design to make it more suitable for human use. The development of a 'glue gun' that 3D prints bone grafts directly onto fractures is a significant breakthrough in medical technology. With further research and development, this innovative device could become a valuable tool for surgeons worldwide, improving patient outcomes and reducing the risk of complications associated with traditional bone grafting techniques. *Reporting by Science.*
