Abstract
A surgical implant includes an interior architecture including at least one ovate or egg-shaped bone contacting element. The at least one egg-shaped bone contacting element being defined by a first wall structure including a superior side portion, intermediate portions, and an inferior side portion. The superior side portion includes a top end defining a first arc radius and the inferior side portion includes a bottom end defining a second arc radius. The first arc radius is smaller than the second arc radius.
Claims13
A surgical implant comprising:
- an interior architecture including at least one egg-shaped bone contacting element, the at least one egg-shaped bone contacting element being defined by a first wall structure including a superior side portion, intermediate portions, and an inferior side portion;
- wherein the superior side portion includes a top end defining a first arc radius and the inferior side portion includes a bottom end defining a second arc radius, whereby the first arc radius is smaller than the second arc radius;
- and
- wherein the at least one egg-shaped bone contacting element includes a height measured from the top end to the bottom end of the first wall structure and a width at a maximum distance measured directly across the intermediate portions, whereby the height is greater than the width.
