摘要:
A tibial prosthesis (10) comprising: a distal surface (35); a proximal surface (34) generically opposed to said distal surface, said proximal surface having a lateral compartment (20) and a medial compartment (22); and a peripheral wall (25) extending between said distal surface and said proximal surface, said peripheral wall defining: a leading edge (202); a lateral rear edge (204) generically opposed to said anterior edge and forming a posterior boundary of said lateral compartment; a medial posterior border (206) generically opposed to said anterior border and forming a posterior boundary of said medial compartment; a lateral periphery extending from said anterior edge to said lateral posterior edge, said lateral periphery defining a plurality of adjacent lateral arches (208, 210, 212, 214, 216) and a medial periphery extending from said anterior edge to said medial posterior edge, said medial periphery defining a plurality of adjacent medial arches (220, 222, 224), characterized by an adjacent pair of said plurality of adjacent lateral arcs defining a first lateral radius and a second lateral radius, respectively, said said first lateral radius greater than said second lateral radius by at least 100%; and an adjacent pair of said plurality of adjacent medial arcs defining a first medial radius and a second medial radial, respectively, said first medial radius being greater than said second medial radius by less than 75%.Una prótesis tibial (10) que comprende: una superficie distal (35); una superficie proximal (34) genéricamente opuesta a dicha superficie distal, presentando dicha superficie proximal un compartimento lateral (20) y un compartimento medial (22); y una pared periférica (25) que se extiende entre dicha superficie distal y dicha superficie proximal, definiendo dicha pared periférica: un borde anterior (202); un borde posterior lateral (204) genéricamente opuesto a dicho borde anterior y que forma un límite posterior de dicho compartimento lateral; u
