Abstract
Improved instruments for modifying a shape of a proximal femur of a patient for installation of a stem of a femoral component of a prosthetic hip during hip replacement surgery, comprising a handle including an elongated shaft extending downward approximately in a z-direction, a first offset extending from a bottom of the elongated shaft approximately in a y-direction, a second offset extending from the second offset approximately in an x-direction, and a shaping member elongated downward from the second offset approximately in the z-direction. Provided is an improved femoral broach and an improved osteotome. Also provided is a method of improving a patient's positioning during hip replacement surgery by using a variable configuration mattress for positioning the patient.
