Abstract:
1. A modular long bone prosthesis system for replacing all or a portion of a long bone having a head and neck at its proximal end and a pivot axis about which the bone with which the long bone articulates pivots at the distal end, the system comprising: a proximal component configured to replace the neck of the long bone and to receive a component for replacing the head at a proximal end, a distal component configured at its distal end to include a pivot axis about which the bone with which the long bone articulates may pivot, a retroversion component, a spacer component, and a stem component and wherein: wherein the proximal component, distal component and retroversion component when coupled form a total long bone prosthesis exhibiting a retroversion angle found in the long bone, the proximal and stem components when coupled form a proximal prosthesis, and the distal and stem components when coupled form a distal prosthesis; wherein the proximal component, distal component and retroversion component when coupled in a first configuration form a right total long bone prosthesis and when coupled in a second configuration form a left total long bone prosthesis; wherein the spacer segment when coupled between the proximal and distal components of the total long bone prosthesis forms a longer total long bone prosthesis; further comprising a plurality of spacer components each having a differing length and configured at one end to mount to one of the distal component and the proximal component and at the other end to mount to one of the retroversion component and the stem component; and further comprising a second stem component and an intercalary component configured at both ends to mount to one of a stem component and a spacer component and the intercalary component first stem component and second stem component when coupled form an intercalary prosthesis.
