(canceled)
A bone graft assembly, comprising:
- a first bone piece having a first mating feature, the first mating feature comprising an outer surface, a peripheral surface, a medial surface, an inner surface, and a core surface;
- and
- a second bone piece having a second mating feature, the second mating feature comprising an outer surface, a peripheral surface, a medial surface, an inner surface, and a core surface,
- wherein the first and second mating features are configured to provide, when approximated, a peripheral engagement zone defined between at least portions of the peripheral surfaces of the first and second mating features, respectively, a medial engagement zone defined between at least portions of the medial surfaces of the first and second mating features, respectively, and an inner engagement zone defined between at least portions of the inner surfaces of the first and second mating features, respectively,
- wherein the inner engagement zone is disposed interior to the medial engagement zone and the medial engagement zone is disposed interior to the peripheral engagement zone, and
- wherein at least a portion of the medial engagement zone is disposed between the core surface of the first mating feature and the outer surface of the second mating feature.

A bone graft assembly, comprising:
- a first bone piece having a first mating feature, the first mating feature comprising a peripheral surface, a medial surface, an inner surface, and a core surface;
- and
- a second bone piece having a second mating feature, the second mating feature comprising an outer surface, a peripheral surface, a medial surface, and an inner surface,
- wherein the first and second mating features are configured to provide, when approximated, a peripheral engagement zone defined between at least portions of the peripheral surfaces of the first and second mating features, respectively, a medial engagement zone defined between at least portions of the medial surfaces of the first and second mating features, respectively, and an inner engagement zone defined between at least portions of the inner surfaces of the first and second mating features, respectively,
- wherein the inner engagement zone is disposed interior to the medial engagement zone and the medial engagement zone is disposed interior to the peripheral engagement zone,
- wherein the medial engagement zone defines an interface having a first contour shape,
- wherein the core surface of the first mating feature defines an interface having a second contour shape, and
- wherein the first contour shape is different from the second contour shape.
