Hip Joint Replacement
Hip joint replacement is surgery to replace all or part of the hip joint with a man-made joint. The artificial joint is called a prosthesis
Your hip joint is made up of two major parts. One or both parts may be replaced during surgery:
The hip socket (a part of the pelvic bone called the acetabulum)
The upper end of the thighbone (called the femoral head)
The new hip that replaces the old one is made up of these parts:
A socket, which is usually made of strong metal.
A liner, which fits inside the socket. It is usually plastic, but some surgeons are now trying other materials, like ceramic. 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 thigh bone to make the joint more stable.
This surgery takes about 1 - 3 hours.
Why the Procedure Is Performed
Your doctor may recommend a hip replacement for these problems:
You can't sleep through the night because of hip pain.
Your hip pain has not gotten better with other treatments.
Hip pain limits or prevents you from doing your normal activities, such as bathing, preparing meals, doing household chores, and walking.
You have problems walking that require you to use a cane or walker.
Other reasons for replacing the hip joint are:
Fractures in the thigh bone. Older adults often have a hip replacement for this reason.
Hip joint tumors
After the Procedure
You will stay in the hospital
for 2 - 3 days. During that time you will recover from your anesthesia, and from the surgery itself. You will be asked to start moving and walking as soon as the first day after surgery.
Some people need a short stay in a rehabilitation center after they leave the hospital and before they go home
. At a rehab center, you will learn how to safely do your daily activities on your own
. Home health services are also available.
Hip replacement surgery results are often excellent. Most or all of your pain and stiffness should go away.
Some people may have problems with infection, loosening, or even dislocation of the new hip joint.
Over time the artificial hip joint will loosen. This can happen after as long as 15 - 20 years. You may need a second replacement.
