Modular necks for orthopaedic devices

Abstract

There is provided a system of modular orthopaedic devices. The system comprises one or more hip implants or trials, each hip implant or trial having a femoral stem and one of at least two neck segments having different geometries. Each neck segment comprises a proximal end configured to receive a femoral head portion and a distal end configured to be operably received by a proximal portion of the femoral stem. Each proximal end comprises a central portion generally representative of a femoral head center. When each of the at least two neck segments are joined with the femoral stem, the central portion is displaced a predetermined distance in a single direction relative to the femoral stem. The neck segments provided, therefore, advantageously allow a user to independently adjust any one of a height, an offset, or a version angle of an orthopaedic device for best performance and fit.
