Abstract
In one embodiment, a surgical guide structure configured for placement on a resected bone surface includes a body with at least one aperture and an opening. The at least one aperture extends through the body and is sized for placement of a hole formation instrument therethrough. Additionally, the at least one aperture is defined by an inner wall that includes a first portion having a first slope and a second portion having a second slope different from the first slope so that a cross-section of the aperture varies over its depth. The opening is sized and positioned so that when the surgical guide structure is positioned on a first resected surface of a bone, the first resected surface and a second resected surface of the bone are visible through the opening.
