Pre-surgery planning and rehearsal using 3D printed models has reduced complex surgeries' time by an hour and improved success rates.

Reduced costs and time for surgeries.

“3D printing allows in-depth assessment and pre-surgical rehearsal. Implants are more accurately fitted to the curvature of the patient's bone.”
Professor Kwok-sui Leung, Departmentof Orthopaedics and Traumatology,Chinese University of Hong Kong

Prince of Wales uses 3D printing in cases ranging from corrective osteotomy (re-alignment of bone from deformity) to complex bone fractures from car accidents, like the above.

Creating innovative approaches.

Elvis Chun-sing Chui, biomedical engineer at the Orthopaedic Learning Centre of CUHK, said, “The adoption of 3D printing provides a platform to experiment with innovative surgical approaches. Moreover, it enhances the communication between medical practitioners and patients. Patients better understand the diagnosis and treatments with the aid of the 3D printed parts.”

Surgeon's pre-surgery planning uses 3D models increases accuracy during the actual surgery. One of the most common incision sites in bone cancer surgeries is at the end of the femur, close to the knee joint.
In addition to printing surgical guides, CUHK and Prince of Wales Hospital have further extended their applications to printing small, single-use surgical tools. For example, frequently it’s helpful for orthopedic surgeons to use a guide to ensure accurate screw placement before inserting them into the bone. These small plastic guides are custom made for each individual patient, based on their unique anatomy and surgical procedure. And because the Fortus 3D Production System can build with PC-ISO®, a biocompatible thermoplastic that is sterilizable, the clinician can use the guides on patients directly from the 3D printer. In one case, the 3D printed guide only cost approximately HKD100 – several times less than traditional manufacturing costs, and much quicker as well.
