Patient-specific femoroacetabular impingement instruments and methods
First Claim
Patent Images
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.

Abstract
A device for a patient-specific acetabular and/or femoral guide. The guides can be used in a selected resection of at least one of a femur and an acetabulum to increase a range of motion of the femur relative to the acetabulum. Generally, a natural acetabulum and femoral head are maintained.

15. 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:
-
using an interactive surgical planning software program, analyzing a three dimensional (3D) model of at least a portion of the femur and the acetabulum based on image data stored on a first non-transitory storage medium; manipulating images of implant components on the 3D model using the interactive surgical planning software program to determine an appropriate resection of at least one of 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 based on the 3D model; designing a patient specific guide instrument configured to guide a resection relative to the femoral neck using the interactive surgical planning software program to remove a defect portion of the femoral neck while leaving the femoral head intact, the patient specific guide instrument including a portion having an inner surface configured to specifically engage the femur of the patient based on the 3D model; outputting a manipulatable surgical plan from the 3D model to a second non-transitory storage medium to assist in designing the patient specific guide instrument, the surgical plan including anatomic data of the femur derived from the 3D model; and resecting the femur of the specific patient during a surgical procedure conducted according to the surgical plan. - View Dependent Claims (16, 17, 18, 19, 20, 21)
