    The hip is a ball (head of the femur) and socket (also called the acetabulum, a cup like structure in the pelvis) joint.

    A hip replacement involves resurfacing the socket on the pelvic side of the hip joint, and replacing the ball at the top of the thigh bone. A stem is placed inside the top part of the femur (thigh bone) to support the new ball. The stem is fixed either with cement or a bone in-growth surface. The new socket surface is usually fixed with a bone in-growth surface and screws.

    The surgery is done through an 6-8 cm cut at the top of your leg on the back. Computer navigation is used to align the components. This involves a couple of tiny incisions at the top of your pelvis.

    The wound is closed with dissolving stitches and dressings (wound coverings) are applied.

    Dr. Cohen uses components with proven results on the joint replacement registry.

    While much has been made of the materials used in hip replacement Dr. Cohen uses either a ceramic or metal on polyethylene (plastic) bearing surface for hip replacement surgery. If you would like to learn more, be sure to ask Dr. Cohen about the materials he has chosen for your hip replacement surgery.
