Surgical technique and instrumentation for minimal incision hip arthroplasty surgery

摘要

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.

主权项

1. A method for preparing a medullary canal of a femur for installation of a stem of a femoral component of a prosthetic hip, comprising:
gaining access to the medullary canal through an incision; creating a cavity in the medullary canal by positioning a shaping member of a device into the medullary canal through the incision by a non-vertical approach to the femur, the device having a double-offset handle permitting aligning of the shaping member with the long axis of the femur while at the same time with the patient in a supine position directing the handle in a medial-lateral direction away from the shaping member and vertically out of the surgical site in an anterior direction; and releasing the handle from the shaping member.
