Analysis of near cortex versus both cortex screw fixation in bone fracture surgery

Bone fractures are common due to accident and falls. The current-state of the art of stabilizing a fracture is by using of Locking Compression Plates (LCPs). Accelerated healing can occur when the blood supply to bone is taken care of. This project seeks to create and validate fracture fixation...
