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.

If you need a steroid injection into the hip for pain from osteoarthritis, there's only a 50-50 chance the agent will actually reach its intended destination. That's the conclusion of this study from Turkey. Using anatomical landmarks to position and advance the needle is called a blind injection. Using this technique with any success is like tossing a coin and shouting heads or tails and then being right (or wrong). What can the physician do to increase his or her accuracy? Use some type of imaging to guide the needle. That could include magnetic resonance imaging (MRI), ultrasound (US), fluoroscopy (real-time 3-D X-rays), computerized tomography (CT scans), or arthrography. Arthrography is a tool doctors use to find the source of patients' symptoms. By injecting a special substance or contrast dye into a painful joint, doctors can see soft tissues and joint structures to find out what may be causing pain and other symptoms. In this study, physicians used fluoroscopy to guide and place...
In the time leading up to hip replacement surgery, you were looking forward to living pain free. But now months after the surgery, you are disappointed with your reality of living with ongoing pain or even worse pain than you had before. What went wrong? Why aren’t you experiencing the pain-free life that you dreamed of? A few things can be going wrong and preventing you from the best possible results after the replacement of your hip.
First and foremost, you might be caught in a painful triad of arthritis involving both the hips and the spine. Replacing one or both hips does not solve the back pain. And fusing the back does not solve the hip pain. The hip-spine connection is frequently encountered in the elderly because all of these parts have deteriorated over time. 1 Sometimes hip arthritis is misdiagnosed as low back pain. Sometimes low back pain is misdiagnosed as hip arthritis. And many times both are seen together in the same person. Even someone who has had t...
