  • Modular stem extension
    Patent number: 9814583
    Abstract: The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.

  • VARIABLE STIFFNESS INTRAMEDULLARY STEM
    Publication number: 20080027559
    Abstract: A variable stiffness stem component for intramedullary fixation in total joint replacement implants or in a segmental replacement system. The stem component has a shaft with a proximal end, a distal end, and a longitudinal length therebetween. The diameter of the shaft is approximately constant along the longitudinal length. A taper or threaded connection may be provided adjacent the proximal end of the shaft for assembly to another implant component. At least three flutes are disposed in a portion of the length of the shaft from intermediate the proximal and distal ends extending towards the distal end. The flutes increase in one of width or depth, or a combination thereof, towards the distal end to provide variable stiffness.
