What is Hip Replacement?
Hip replacement surgery is a procedure in which a doctor surgically removes a painful hip joint with arthritis and replaces it with an artificial joint often made from metal and plastic components. It usually is done when all other treatment options have failed to provide adequate pain relief. The procedure should relieve a painful hip joint, making walking easier.
Causes of Hip Replacement
There are two main conditions that can end up with you needing a hip replacement:
If you have arthritis in your hip:
Arthritis means inflammation of a joint.
Osteoarthritis is the most common cause of arthritis in the hip and the most common reason for needing a hip replacement.
Rheumatoid arthritis is a less common cause. About one person out of every 21 who has a hip replacement has rheumatoid arthritis.
There are other causes of arthritis that may lead you to need a hip replacement.
If you break your hip (hip fracture):
A hip fracture is a fracture of the top part of the thigh bone (femur). The fracture can be of the head, of the neck or below the neck.
Usually ,a hip fracture is treated by an operation to screw the broken ends back together again. However, if it is the head of the femur that has broken, this is often treated by replacing the broken head of the femur with an artificial head of the femur (prosthesis). This is particularly the case if the broken bits have moved away from each other or if you already have arthritis in that hip joint.
What Are the Symptoms of Osteoarthritis of the Hip?
There are some of the following symptoms of hip osteoarthritis:
- Joint stiffness that occurs as you are getting out of bed
- Joint stiffness after you sit for a long time
- Any pain, swelling, or tenderness in the hip joint
- A sound or feeling (“crunching”) of bone rubbing against bone
- Inability to move the hip to perform routine activities such as putting on your socks
Hip Replacement Surgery Procedure
Surgical procedures differ depending on the patient’s needs and the surgeon’s approach, but generally, the steps are as follows:
The patient’s vital signs are checked to make sure blood pressure, heart rate, body temperature, and oxygenation levels are normal and surgery can proceed. A mark is made on the hip undergoing surgery.
Anesthesia is administered. A patient may receive general anesthesia (be put to sleep) or be given a regional anesthesia to block sensation from the waist down, along with a relaxant. The type of anesthesia a patient receives is decided well ahead of time.
The surgeon makes a 10 to 12 inch incision, usually at the side or back of the hip, cutting through skin and then through muscle and other soft tissue to expose the bones at the hip joint. A surgeon performing minimally invasive total hip replacement will make a smaller incision and/or cut through less soft tissue.
The surgeon dislocates the joint, removing the head of femur from its socket in the pelvis. This socket is called the acetabulum.
The arthritic femoral head is cut off with a bone saw.
The surgeon prepares the acetabulum for its acetabular cup prosthesis by using a special tool called a reamer to grind down and shape the socket.
Risks associated with hip replacement surgery may include:
Blood clots: Clots can form in your leg veins after surgery. This can be dangerous because a piece of a clot can break off and travel to your lung, heart or rarely your brain. Your doctor may prescribe blood-thinning medications to reduce this risk.
Infection: Infections can occur at the site of your incision and in the deeper tissue near your new hip. Most infections are treated with antibiotics, but a major infection near your prosthesis may require surgery to remove and replace the prosthesis.
Fracture: During surgery, healthy portions of your hip joint may fracture. Sometimes the fractures are so small that they heal on their own, but larger fractures may need to be corrected with wires, pins, and possibly a metal plate or bone grafts.
Dislocation: Certain positions can cause the ball of your new joint to become dislodged, particularly in the first few months after surgery. If the hip dislocates, your doctor may fit you with a brace to keep the hip in the correct position. If your hip keeps dislocating, surgery is often required to stabilize it.
Change in leg length: Your surgeon takes steps to avoid the problem, but occasionally a new hip makes one leg longer or shorter than the other. Sometimes this is caused by a contracture of muscles surrounding the hip. In this case, progressively strengthening and stretching those muscles may help.
Loosening: Although this complication is rare with newer implants, your new joint may not become solidly fixed to your bone or may loosen over time, causing pain in your hip. Surgery might be needed to fix the problem.
