Surgical instrumentation and methods of use for implanting a prosthesis

A method of resecting bone comprising:

• aligning a surgical device having first and second resection planes, wherein the first resection plane is approximately perpendicular to a longitudinal axis of a first bone and the second resection plane is transverse to the first resection plane;
• resecting the first bone by cutting along each of the first and second resection planes;
• resecting a second bone by cutting along a third resection plane of the surgical device to create a first surface,
• positioning a first guide at least partially on the first surface of the second bone;
• resecting the second bone using a first resection tool advanced over a guide surface of the first guide to create a second surface of the second bone defined at an angle relative to the first surface of the second bone and abutting the first surface;
• and
• resecting the second bone using a second resection tool placed through a second guide to create a third surface of the second bone defined at an angle relative to the first surface of the second bone and separated from the second surface of the second bone by the first surface,
• wherein the first guide and the second guide are separate parts that are attached to one another after the positioning step.
