Abstract:
1. An intramedullary fixation device comprising: a first intramedullary component sized and configured to be received wholly within an intramedullary canal of a bone, the first intramedullary component having a substantially solid first bone-attachment end and a first elongated member monolithically extending from the first bone-attachment end along a longitudinal axis of the intramedullary fixation device, the first elongated member having a width smaller than a corresponding width of the first bone attachment end, the first bone attachment end defining at least one transverse pin aperture for bone attachment, the first bone attachment end sized and configured to substantially seal the intramedullary canal; a second intramedullary component sized and configured to be received wholly within the intramedullary canal, the second intramedullary component having a second bone-attachment end and a second elongated member monolithically extending from the second bone-attachment end along the longitudinal axis, the second elongated member having a width smaller than a corresponding width of the second bone attachment end, the second intramedullary component defining a sleeve having an axial bore extending through the second bone attachment end and through the second elongated member such that the first elongated member can pass therethrough, the second bone attachment end defining at least one transverse pin aperture for bone attachment; a compliant member coupling the first and second intramedullary components within the intramedullary canal, the compliant member configured and positioned relative to the first and second intramedullary components for applying bone-compressing stress; and a modular adapter removably coupled to the first attachment end via a taper connection along the intramedullary canal, the modular adapter couplable to an external prosthetic device.
