Abstract
Abstract A modular hip prosthesis for the replacement of a portion of the femur is provided. The prosthesis is assembled from a kit that includes a stem member having an upper portion and a lower portion, with the lower portion sized to be received in the femur. The kit also includes a body member that is sized to replace a portion of the femur and is configured to be received over the upper portion of a stem member. The kit also includes a head member that is sized to replace the head of the femur. A neck member is provided to attach the head member to the body member to form an assembled prosthesis.
