Abstract
An orthopaedic surgical implant apparatus includes an elongated intramedullary rod assembly 10 for use in uniting a pair of bone segments wherein each of the bone segments includes a medullary cavity. The elongated intramedullary rod assembly 10 defines a central longitudinal axis when assembled and includes first and second points of attachment 26, 48, the rod assembly 10 being adapted to be positioned within the medullary cavities of the bone segments and secured to the first bond segment at the first point of attachment 26 and to the second bone segment at the second point of attachment 48. Structure 18, 52 is provided for shortening the predetermined distance between the first and second points of attachment 26, 48 of the rod assembly in the direction of the longitudinal axis after the rod assembly has been connected to the first and second bone segments so that the first and second bone segments are brought into contact with and press against one another. A method of implanting the apparatus is also disclosed.
