1. A method of resecting a selected portion of an anatomy to improve range of motion of a femur relative to a pelvis in a specific patient, comprising:

  • accessing from a first non-transitory storage medium image data of the patient including at least a portion of the pelvis and a portion of the femur at least including a femoral head of the femur and an acetabulum of the pelvis;

    generating and displaying on a computer display a three dimensional (3D) model of at least a portion of the femur and the acetabulum based on the accessed image data;

    determining using an interactive surgical planning software program in communication with the first non-transitory storage medium and computer display an appropriate resection of a defect portion of a femoral neck positioned to impinge on the acetabulum to obtain a selected range of motion of the femur relative to the pelvis after a resection;

    designing a patient specific guide instrument configured to guide the resection relative to the femoral neck, the patient specific guide instrument including a portion having an inner surface configured to specifically engage the femur of the patient based on the generated 3D model of at least the femur;

    transferring to a second non-transitory storage medium a surgical plan including the appropriate resection and the patient specific guide instrument;

    manufacturing the designed patient specific guide instrument based on the surgical plan; and

    sending the manufactured patient specific guide instrument to a user to perform the resection.
