An orthopaedic skeletal joint demonstration aid for demonstrating surgical orthopaedic techniques includes first and second joint portions capable of being manipulated relative to one another to mimic the action of a skeletal joint. The first joint portion is detachably secured to one end of an elongate first shaft portion to enable replacement of the first joint portion. An adjustable holding mechanism holds a part of the first shaft portion remotely of the one end in a required position such that the first joint portion is at the correct anatomical orientation for the purposes of the required surgical orthopaedic procedure. The holding mechanism includes an adjustable ball and socket joint and a locking mechanism for locking the ball and socket joint when the first shaft portion is in the required position. A foot plate is provided for holding the second joint portion, and the second shaft portion in the required position.
