abstract

Advanced simulation techniques in computer-assisted surgery is not only the key element towards development of computer based systems for optimized implant design, but they will also allow surgeons to reliably replace the damaged joints, even when significant bone loss has occurred. Since the main objective of the surgical procedure is to accurately replicate the native articulation of the elbow, the overall success of the joint arthroplasty is decisively influenced by the preoperative planning procedure aiming to establish the presence of a feasible position of the implant that will essentially cause a minimal malalignment of the prosthetic flexion-extension (FE) axis of the joint with respect to the native one. Any malalignment between native and artificial axes will eventually alter the kinematics of the joint and will lead to implant failures.
