Total Hip Arthroplasty is reportedly superior to Bipolar Hemiarthroplasty in terms of hip pain, function and reoperation rate. Total Hip Arthroplasty has a higher rate of dislocation rate than Bipolar Hemiarthroplasty.

Hip precautions are unnecessary after hemiarthroplasty, cost money both in therapist time and equipment provision and increase the length of hospital stay. Nevertheless, they continue to be used by three-quarters of trauma hospitals in England.

The components of a total hip prosthesis include the acetabular cup, the femoral head, and the femoral stem. These components can be constructed from a metal alloy (cobalt-chrome, stainless steel, titanium, tantalum), plastic (ultra-high-molecular-weight polyethylene), or ceramic (aluminum oxide, zirconium oxide).

Hemiarthroplasty is a surgical procedure that replaces one half of the hip joint with a prosthetic, while leaving the other half intact. There are several different options available for the type of device to be used; we prefer to use a bipolar type, which has a femoral head that swivels during movement.

Although some old MRI scanning equipment may not be compatible with your prosthesis, the majority of MRI scanning equipment today is safe and compatible with hip replacement parts. You also may have a CT scan of any part of your body after a hip replacement.

Typically, hip replacement surgery takes two hours. However, your operation’s timeframe depends on the severity of your condition and any complications that may arise during the operation. It also depends on whether you’re receiving a full or partial hip replacement.

Depending on the surgeon’s preference and surgical technique, the patient may be given ” hip precautions ” to prevent the implant from dislocating. These “precautions” include: avoiding crossing the legs, as well as excessive bending or rotating of the hip.

In some patients, a small amount of pain or instability can occur after hip replacement surgery. There may also be stiffness, bleeding or nerve injury. Patients usually experience relief from pain or increased mobility following a recovery period.

Bipolar replacement, or arthroplasty, is one type of partial hip replacement that is frequently done for fractures, but can also be done for arthritis, avascular necrosis, and other problems about the hip. It is an option when there is disease of the femoral head, but the acetabulum or socket is not involved.

The average actual hospital cost for total hip arthroplasty increased 46.5 per cent, from $8428 in 1981 to $12,348 in 1990.
