Patient-Specific Femoroacetabular Impingement Instruments And Methods

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 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 a three dimensional (3D) model of at least a portion of the femur and the acetabulum based on the accessed image data;
• determining a appropriate resection of at least one a femoral neck relative to another portion of the femur or the acetabulum to obtain a selected range of motion of the femur relative to the pelvis after the resection;
• and
• designing a patient specific resection guide to guide a resection instrument relative to the femoral neck to perform the resection, wherein the patient specific resection guide includes a guide portion having an inner surface configured to specifically engage the femur of the patient and a guide surface to guide a guide arm to move relative to the guide portion based on the generated 3D model of at least the femur.

A kit of instruments to resect a selected portion of an anatomy to improve range of motion of a femur relative to a pelvis in a specific patient, comprising:

• a femoral neck resection guide including a guide dome having an inner surface configured to match the specific patient and a guide surface to guide a guide arm during movement relative to the guide dome;
• and
• a greater trochanter fixation member sized to pass through the greater trochanter and engage cortical bone near the lesser trochanter of the specific patient,
• wherein the kit of instruments is operable to assist in a resection of the femur.

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 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 a three dimensional (3D) model of at least a portion of the femur and the acetabulum based on the accessed image data;
• determining an appropriate resection of at least one a femoral neck relative to another portion of the femur or the acetabulum to obtain a selected range of motion of the femur relative to the pelvis after the resection;
• and
• designing a patient specific tissue removal template to guide a resection relative to the femoral neck to determine when a selected resection of the femoral neck is complete, wherein the patient specific tissue removal template includes a template 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.

A system to resect a selected portion of an anatomy to improve a range of motion of a femur relative to a pelvis in a specific patient, comprising:

• a greater trochanter guide including an anatomy contacting surface that is a negative of and operable to contact the anatomy of the specific patient in a substantially single position, wherein the greater trochanter guide includes:
• a cutting guide slot configured to be positioned at a patient specific location relative to the femur of the patient;
• and
• a drill guide portion operable to orient a drill guide passage at a specific location relative to the femur of the patient.
