How Does Your Hip Work?

The hip is a simple ball-and-socket joint where your thigh bone joins with your pelvis. Surrounded by cartilage, muscles and ligaments, your hip is the largest weight-bearing joint in your body. Smooth cartilage and bone help you walk easily and without pain.

The hip joint is powered by large muscles and is covered with a rubbery type of tissue that pads the joints. When all of the parts, cartilage, muscles and tendons are healthy, a hip should move easily.

A hip is diseased when one or more parts of the hip are damaged and movement becomes stiff. Over time, cartilage starts to crack or wear away. When this happens, the bones making up the joint rub together. Stiffness and pain occur when the ball starts to grind in the socket. Unfortunately, cartilage does not have the ability to repair or replace itself like other tissues in the body. Once cartilage is damaged or destroyed, it is gone forever.

What Is Hip Replacement?

Total hip replacement involves removing the diseased bone and cartilage and replacing them with orthopaedic implants.

The surgical procedure involves an incision through the skin to gain access to the hip joint through the muscles overlying the hip, all done while the patient is under anesthesia.

Total Hip Replacement Procedure

The hip socket (acetabulum) is prepared by using special instruments to make it the right size and shape for a new implant. The femoral head is replaced with an artificial ball on a stem that goes down into the hollow part of the thighbone and may be pressed into place or cemented, depending on the surgeon’s preference. A metallic shell with a cup-shaped liner is pressed into the prepared socket to provide a smooth gliding surface. The ball and socket are then placed together to complete the procedure.

For Bill, debilitating hip pain kept him in the wings. Now, he’s dancing his way back to an active lifestyle thanks to his total hip replacements.

Exactech Hip System

Designed to Maximize Range of Motion

Exactech’s total hip implants are designed to maximize range of motion through innovative designs that provide strength while preserving as much of a patient’s natural anatomy as possible.

Exactech Hip System Features

  • Components

    A number of advanced bearing materials and proven design features that reduce the amount of wear and stress on each component, helping to increase the longevity of the artificial joint

  • Materials

    Titanium, the material used in many femoral hip stems, has been shown to stimulate the body’s natural bone growth, promoting stability of the implant.1,2

Surgical Approaches

Direct Anterior Approach

The direct anterior approach to hip replacement surgery allows the surgeon to access the diseased hip joint through the front of the hip. A major advantage of this approach is that it allows your surgeon to work through natural intervals between the muscles around your hip, without having to cut through the muscles or detach them from the pelvis or thighbone.

This preservation of your soft tissues may result in a faster return to weight-bearing activities, less pain and a quicker overall recovery time. Keeping these muscles intact may also help reduce the likelihood of dislocation, which may occur when muscles weakened in surgery are not strong enough initially to keep the new femoral head in the socket. The patient can also avoid the pain of sitting on the incision site since the anterior approach is performed through the front of the hip.

Why aren’t all hip replacements performed through the anterior approach?

Hip replacement can be performed through:

  • the back of the hip (posterior approach)
  • the side of the hip (lateral or anterolateral approach)
  • the front of the hip (anterior approach)
  • or through a combination of approaches.

Direct anterior approach hip surgery requires implants and surgical instruments that are compatible with the approach. Specialized surgical tables, although not necessary, may facilitate the anterior approach by allowing precise positioning of the patient during surgery.
