Articular congruency of the Salto Talaris total ankle prosthesis

Highlights • The surface contour of polyethylene bearings in total ankle is not well described. • Semi-constrained prostheses allow for multiple degrees of freedom of motion. • Computer simulated imaging of Salto-Talaris prosthesis reveal incongruent surfaces. • The points of bearing contact will be...

Description
Summary:Highlights • The surface contour of polyethylene bearings in total ankle is not well described. • Semi-constrained prostheses allow for multiple degrees of freedom of motion. • Computer simulated imaging of Salto-Talaris prosthesis reveal incongruent surfaces. • The points of bearing contact will be smaller with incongruent bearing surfaces.
