A total hip replacement replaces your arthritic hip joint and eliminates the damaged bearing surfaces that are causing pain. The design of the implant offers you renewed stability and minimizes the wear process. The traditional metal and polyethylene implants have been in use since the 1960’s but technological advances since then have made other materials such as ceramic increasingly popular.
During a hip replacement, the head of the femur (thigh bone) is first removed. Then a metal liner or cup is placed in the socket (acetabulum) which sometimes is fixed into the socket with 2 or 3 screws. Into this is placed a plastic, metal or ceramic liner. The femur has a metal stem inserted then a ball fitted on top. This ball can be anything from 28mm to 58mm in diameter and made from metal or ceramic. The ball is fitted into the cup and the new joint is created.
In terms of fixation, your surgeon has the choice of anchoring the hip implants securely to bone using either cement fixation or fixation by ‘bone in-growth’.
Your surgeon will select the design of the hip replacement and size of femoral ball to give you the range of motion and stability that you need to function. There are several different choices of hip implants to consider, each using varying materials and having different pros and cons.

At first, you could control daily hip discomfort with over-the-counter painkillers, but now even that doesn’t work, so you make an appointment to see your doctor, wondering if you need a hip replacement. To maximize the benefits of that appointment, here are three questions to ask your doctor: Do I really need a hip replacement? How accurate is the placement of the components? How minimally invasive is the surgery?
Below are the answers you should hear.
Do I really need a hip replacement?
First, your doctor should make every effort to help you avoid a hip replacement for as long as possible because hip replacements use artificial components, which have a shelf life. That means they will wear out and need replacing. Unfortunately, each time a surgeon replaces a hip, the patient loses some bone. Therefore, the goal is to preserve the natural hip for as long as possible and perform surgery only when it is strictly necessary.
Although various congenital disorders may lead to hip replacement surgery, the most common reason for undergoing one is arthritis. If a hip has only mild arthritis and no longer responds to non-steroidal anti-inflammatory medication and rest, your doctor may recommend physical therapy and/or injections to reduce inflammation, which may then alleviate stiffness, swelling and pain.

The many baby boomers considering hip or knee replacements in the coming years are likely to have to pay more to get them. The question is, How much more? And could the problems stretch beyond a higher price tag?
Under the Affordable Care Act, the Obama administration’s signature health-care-overhaul law, medical-device manufacturers will pay a 2.3% tax on sales of such products starting in 2013. That tax will affect everything from surgical tools to oxygen tanks to wheelchairs. It is one of several features of the law designed to raise money to cover the uninsured — it’s expected to raise an additional $20 billion by 2019.
