The self-contouring plate system for bone fractures with anti-rotation stop allows a surgeon to bridge a bone fracture, primarily in bones of complex shape where the use of plates or screws is difficult. The self-contouring plate is formed from a series of similar or identical rigid elements, the elements able to bend and rotate with respect to each other. This flexibility is initially helpful as the surgeon contours the device to the shape of the bone. When the desired shape is reached, the elements are locked into place. The length of device is adjusted by adding or removing elements, much like a necklace. Each element of the self-contouring plate includes a ball that extends away from a body, a cavity for receiving the ball of the neighboring plate, and a screw to compress the ball within the cavity.
