Abstract
The invention provides an osteotome which includes a curved guide member extending distally from its medial side. This curved guide member interfaces with the medial curvature of the femoral canal. The guide member guides the osteotome using the internal bone geometry of the femoral canal instead of relying on external anatomical landmarks.
Claims11
An osteotome for preparing a proximal end of a femur of a patient for installation of a stem of a femoral component of a prosthetic hip during hip replacement surgery, the osteotome comprising:
- a body having
- a proximal end connectable to a handle, and
- a distal end having a cutting edge, and
- a curved guide member extending in a distal direction from the distal end of the body.
A method of preparing a proximal end of a femur for installation of a femoral component of a prosthetic hip, comprising steps of:
- (a) using an osteotome comprising
- a body having
- a proximal end connectable to a handle and
- a distal end having a cutting edge, and
- a curved guide member extending in a distal direction from the distal end;
- (b) positioning the osteotome at a proximal end of the femur;
- (c) inserting a distal end of the curved guide member into a canal of the femur;
- (d) shaping the proximal end of the femur with the osteotome.
