Surgical guide for femoral resection
First Claim
Patent Images
1. A femoral neck resection guide, comprisinga rigid frame formed of an elongate member, the frame having distal and proximal ends disposed along a longitudinal frame axis;
- a gauge movable relative to the frame and means disposed on the frame between the distal and proximal ends of the frame for referencing the resection guide to anatomical features of a patient'"'"'s femur;
a surgical reamer having a longitudinal axis for insertion into the intramedullary canal of the fermur;
clamp means disposed on the proximal end of the frame for securing the resection guide in a fixed position relative to the surgical reamer so that the longitudinal axis of the surgical reamer is substantially parallel to the longitudinal frame axis; and
a resection guide surface on the distal end of the frame for defining a resection line for a femoral neck, and said gauge being movable relative to said guide surface.

Abstract
A surgical resection guide enables a surgeon to resect a femoral neck, during a hip arthroplasty procedure, such that a femoral prosthesis can be implanted within a patient to preserve or closely approximate the anatomic center of rotation of the hip. The guide is able to be used for left or right hip arthroplasty procedures, with either anterior or posterior surgical approaches.

7. A method for defining a femoral neck resection line, comprising the steps of:
-
providing a femoral neck resection guide, comprising a rigid frame formed of an elongate member, the frame having distal and proximal ends disposed along a longitudinal frame axis, a movable gauge means disposed on the frame between the distal and proximal ends of the frame for referencing the resection guide to anatomical features of a patient'"'"'s fermur, clamp means disposed on the proximal end of the frame for securing the resection guide in a fixed position relative to the femur, and a resection guide surface associated with the distal end of the frame for defining a selected resection line through a femoral neck; referencing the resection guide to anatomical features of a patient'"'"'s femur by vertically positioning the moveable gauge means relative to the rigid frame to indicate the anatomical center of rotation of the femur; and fixedly positioning the resection guide relative to the femur such that the frame extends substantially parallel to and offset from the longitudinal axis of the femur and such that the resection guide surface is disposed adjacent to the femoral neck to define the selected resection line through the femoral neck. - View Dependent Claims (8)
