摘要：
A talonavicular joint prosthesis (1) adapted to replace the natural talonavicular joint that exists between a patient's talus and navicular bones, after appropriate surgical preparation of the joint-related portions of these bones so as to create a new joint space to accommodate this prosthesis, includes talar (2) and navicular (4) components. Each of these have inner (8, 28) and outer (6, 26) surfaces whose average separate distance is defined as the component's average thickness. These components inner (8, 28) surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each component's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection in the creation of the new prosthesis-accommodating, joint space.
