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...
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...
Lately, I’ve found that my hips have stiffened up. According to my massage therapist, part of the reason is due to lower back issues that I’ve been facing. It turns out that my lower back has recruited my hip muscles into a revolt that at times can be uncomfortable and at times can be downright painful.
And I’m not alone because, unfortunately, stiff hips can be part of aging for women. In her book, “Fit and Fabulous After 40,” Denise Austin notes that women’s hips differ from men’s. “Our hip socket is called a Q socket, and unlike men, the line from knee to hip isn’t straight; our femurs, or upper leg bones, fit into the hip socket at an angle,” she writes. “For this reason, women tend to experience more hip problems are they grow older.” She notes that issues with your hips can impact your ability to walk and also can lead to back pain and other injuries. Plus, I want to do everything I can to avoid getting arth...
