Medical errors are a fact of life. Doctors do everything they can to reduce errors whenever possible. In the world of orthopedics leg length discrepancy after total hip replacement (THR) is one of the more common types of error. Dr. Clark and his associates from the University of Iowa Hospitals report on this problem. Patients who are unhappy with the results of their THR often have a leg length discrepancy. This is an unexpected and uncomfortable result. Sometimes there is pain involved because of nerve damage. Problems can occur with walking and balance. Severe neurologic symptoms are possible. What can be done to prevent this from happening? Dr. Clark advises orthopedic surgeons to do three things. First assess the patient for leg differences carefully before surgery. Ask the patient if the legs feel equal. Do they use a shoe lift? Ask about the history of any conditions that can have an effect on leg length. Second, check for muscle tightness and measure for length differences. These...
Pain in the groin or buttocks with a loss of hip motion requires special attention. Early diagnosis and treatment is imperative to avoid degenerative changes in the hip joint later in life. There are many possible causes of this type of hip pain. In this article, surgeons from the Rochester, Minnesota Mayo Clinic focus on femoroacetabular impingement (FAI) as a cause of hip pain leading to hip osteoarthritis. Femoroacetabular impingement (FAI) describes a condition where the top of the femur (thigh bone) pinches the rim of the hip socket. The area that gets compressed is referred to as the acetabular rim . This type of impingement occurs most often when the hip is flexed and internally rotated. For a long time, it was believed that FAI only occurred in people with some kind of abnormal anatomy of the hip. There was either a backward tilted angle of the hip socket called retroversion , a larger socket than the ball (head of the femur) inside the socket, or flattening of the femoral head. O...
Hip joint replacement is surgery to replace all or part of the hip joint with an artificial joint. The artificial joint is called a prosthesis .
Hip arthroplasty; Total hip replacement; Hip hemiarthroplasty
The artificial hip joint has four parts:
A socket that replaces your old hip socket. The socket is usually made of metal.
The liner, which fits inside the socket. It is usually plastic, but some surgeons are now trying other materials, like ceramic and metal. The liner allows the hip to move smoothly.
A metal or ceramic ball that will replace the round head (top) of your thigh bone.
A metal stem that is attached to the shaft of the thigh bone to make the joint more stable.
You may receive general anesthesia before this surgery. This means you will be unconscious and unable to feel pain. You may have a spinal or epidural anesthesia. In this kind of anesthesia, medicine is put into you...
