A self-contouring plate system for bone fractures comprises a plurality of rigid plate elements connected by ball-and-socket joints. Each plate element includes a ball at one end and a socket at an opposite end for receiving a ball from an adjacent plate element. A single fastener for each plate element serves the dual function of securing the plate to bone and compressing the ball into the socket to lock the joint. The fastener includes bone threads for engaging bone and a head with a lower surface that directly contacts and compresses the ball. The system allows initial flexibility for contouring to complex bone shapes, then locks into position when the fasteners are tightened. The length is adjustable by adding or removing plate elements. Each plate element maintains substantially uniform thickness without protruding elements, and the balls are solid spherical members without through-holes to maximize strength and range of motion.
