Tools may be used individually and/or in combination to allow minimally invasive and safer orthopedic surgery. A femur adjustment tool lifts and lateralizes the proximal end of the femur during hip replacement surgery by pivoting on a ball temporarily placed in the acetabulum. A tissue protection and broach (rasp, cutting, drilling) guide tool may retract tissue at the incision, protect tendons and soft tissue, nd provides a curved, elongated surface that cradles and guides the broaching tool. A tip of the main body of the protection and guide tool, and a hook protruding from the main body, may extend along opposite surfaces of the femur to help "capture" a portion of the femur for tool stability and to effectively and positively protect the piriformus tendon that will reside in the "V" between the hook and tip. A bone clamp is used when a generally transverse cut is made across a bone, for example, a knee surgery proximal tibial cut, wherein the clamp improves control of the bone portion for safer freeing of the bone portion from soft tissue and extracting the bone portion from the incision. A broad, flat plate of the bone clamp may be slid between the bone and the bone portion into the narrow space that has been created by cutting the bone, and a relatively narrow gripping member may be slid along/across the opposing surface of the bone portion, which allows the narrow gripping member to fit into the intercondylar notch of the femur. |
