Anatomy of the Hip
The hip joint is a ball-and-socket joint. The ball at the top of the thighbone, is referred as the femoral head whereas the socket which is the part of the pelvis is referred as acetabulum. The ball that rotates in the socket allows the movements of the leg. The cartilage which is the soft tissue covers the ball and the socket and helps them to glide together smoothly. In case if the cartilage wears down or is damaged then the bones scrapes together and become rough which leads to severe pain and makes it difficult for the leg to move. Hip Replacement Surgery is recommended in such cases where all other conservative treatments have failed to provide the patient with relief.
What is Hip Replacement Surgery?
Hip replacement surgery is also referred as hip arthroplasty. This surgery provides patients with relief from the severe pain and restores the movement of people who have severe pain or stiffness in the hip. Mostly hip replacement surgery is performed to remedy hip arthritis. Hip arthritis is where the cartilage between the bones of the hip joint wears down which leads to scraping of the bones together causing more damage, stiffness, and pain. Arthritis of the hip can be very painful and can restricts person’s movements. Hip replacement surgery is also performed to fix injuries such as bone breaks, hips that grow incorrectly, and other conditions related to hip.
Who Needs Hip Replacement Surgery?
People who are suffering from the following are recommended with hip replacement surgery:-
- People who have severe and persistent pain in the hip.
- People who experience limited mobility.
- Stiffness in the hip joints.
- Failure of any medications and treatments.
- People suffering from rheumatoid arthritis which leads to inflammation in the joints.
- People with swelling in the hip joints.
- People who experience worsens walking condition.
- People who experience difficulty in rising from a seated position.
- People suffering from traumatic arthritis which damages the joint.
- People suffering from osteoarthritis which is a degenerative form of arthritis and is most common in older people.
How Is the New Hip Constructed?
The Hip Replacement Surgery is made up of the following four components:-
- The metal socket.
- The liner to help the ball move easily within the socket.
- Metal or ceramic ball to replace the femoral head.
- The metal rod which is used to stabilize the thigh bone to which the ball is attached.
Types of Joint Prosthesis
There are different types of joint prosthesis. Most orthopedic surgeons use an uncemented joint prosthesis. This prosthesis allows the bone to grow into the prosthesis with time. Whereas cemented prosthesis is attached to the hip with bone cement for quicker adhesion. Uncemented joint prosthesis and cemented joint prosthesis varies in terms of recovery.
