| Abstract Scope |
The osteocutaneous radial forearm free flap serves as a versatile donor site for various oromandibular and maxillofacial reconstruction surgeries. However, surgeons are hesitant to use this free flap as it has high donor site morbidity and post-operative radius bone fractures are common. The current solution utilizes standardized 3.5mm low-contact dynamic compression plates to stabilize the donor flap cavity. These plates have reduced the likelihood of post-operative fractures but have not eliminated the risk. This study explores the effectiveness of custom, patient specific plating solutions that are made uniquely for each patient’s donor site but also provide surface stabilization and encapsulate the donor cavity volume. This study focuses on laser powder bed additively manufactured titanium plates. Preliminary custom plate designs that both stabilize the surface and encapsulate the cavity volume are modeled using industry standard CAD software. Stress analysis is conducted in ANSYS Mechanical using 3D scan renders of synthetic radius bones. Finite element analysis is performed for intact bone models, flap harvested-no plating, and flap harvested-custom plating bone models. Loading conditions represent the common biomechanical loads that the radius bone experiences daily to accurately simulate the average stresses induced for a patient post operation. |
