Design Philosophy
The overriding design goal was to reproduce the normal anatomy and biomechanics of the human elbow while not using cement to gain component fixation. We derive secure connectivity between implant and bone through intramedullary screw fixation. We created an implant that closely matches the typical dimensions and architecture of the distal humerus and proximal ulna. Secure polyethylene fixation is achieved with a mechanism that allows replacement of this wear surface. Three different implant sizes were designed to match the patient's anatomy. Reproducing anatomy extends to maintaining the radial head the medial and lateral collateral ligaments, which are the primary soft tissue stabilizers of the elbow and are reconstructed during the implantation of this total elbow arthroplasty.
