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.

Described herein are systems and methods in which a surgeon can use computer-implemented deformity assessment and correction tools to create 3D models of a bone. To ensure adequate healing, a surgeon may choose to use a prefabricated bone plate, a semi-customized bone plate, or a fully-customized bone plate to hold first and second bone portions in a corrected position. To select the appropriate prefabricated bone plate, the surgeon may identify three landmark locations on the first and second bone portions corresponding to desired fixation hole locations on the bone plate. The surgeon can then use a software application to evaluate multiple bone plate designs in a library and compare the average proximity of the landmark locations to fixation hole locations on each of the bone plate designs. Then, the surgeon can determine which bone plate design best fits the patient anatomy based on his comparison.
