ABSTRACT:
An implantable modular orthopedic prosthesis, preferably for hip or knee arthroplasty, is disclosed which consists of three components. A first component has an elongated stem with a free end, configured to be situated within the intramedullary canal of a patient's bone, and an opposite end having an articulating portion such as a Morse-tapered member. A second component has another articulating portion which can also be a corresponding Morse-tapered member that is matingly engageable with the articulating portion of the first component. A third component has a body with a linearly-extruded channel through which the articulating portions are adjustably received, wherein at least one of the components is radially-expansible to pressure lock against an internal surface of the channel in a selected position and arrest the first, second and third components together as the articulating portions are fully engaged with one another. The present modular orthopedic implant functions as a unitary biomechanical structure and is easy to use, as it is interoperatively adjustable to fit minute variations in a patient's given anatomy, while minimizing the inventory of component sizes needed on hand during surgery.
