OUR GOAL

This design is focused on faster and safer rehabilitation from a boxer fracture that needed surgical realignment. Although there are several methods of surgical fixation, this design is based on the Plate and Screw fixation which is favored for its biomechanical stability compared to K-wires. However, the issue that does arise with this method is significant stiffness thus limited recovery of motion.

Our design is to fix this by implanting a biodegradable screw and rod device that will physically look the same as the plate and screw fixation but entirely differ in material.

MATERIAL

According to research a highly plausible material for this implant is biodegradable magnesium alloy or WE43. Advantages of using WE43 for this design include no need for removal surgery, high biocompatibility, elastic modulus, and similar strength to human bone than comparative polymer-based devices.
