Abstract
A kit of patient-specific guides for use in preparing a proximal femur to receive a prosthesis is described, and includes patient-specific preparation guides. The femoral resection guide has a body including a proximal cut guide surface and a distal conforming surface contoured to rest against and substantially conform to a femoral neck and/or a metaphysis of the proximal femur. The proximal cut guide surface is configured to guide a cutting instrument for resecting the head of the proximal femur. The femoral canal preparation guide has a body including a proximal surface and a distal surface having a first confirming portion contoured to rest against and substantially conform to an unresected portion of a femoral neck and/or a metaphysis of the proximal femur. The body includes a guide aperture extending therethrough that is dimensioned to guide an instrument for preparing a canal of the proximal femur.
