Скачать или смотреть Hip Replacement-from a patients perspective

I recently had a hip replacement after years of needless suffering, pain, and immobility.
Hip replacement surgery, or hip arthroplasty, is a surgical procedure in which an orthopedic surgeon removes the diseased parts of the hip joint and replaces them with new, artificial parts. These artificial parts mimic the function of the normal hip joint.

You may need hip replacement surgery if you have a disease, such as:

Arthritis, including osteoarthritis and rheumatoid arthritis.
Osteonecrosis, which happens when parts of a bone die due to decreased blood supply.
You may also need hip replacement surgery if you fracture (break) your hip from an injury, such as a fall, or from a bone disease.

The hip joint is a ball and socket joint and is one of the largest joints in the body. The upper end of the femur (thigh bone) meets the pelvis (hip bone) to create the joint. The “ball” at the end of the femur is called the femoral head and fits into the “socket” (the acetabulum) in the pelvis.

The goals of hip replacement surgery include:

Relieve pain from the damaged or diseased hip joint.
Improve the function of the hip joint.
Increase mobility.
During a hip replacement, the surgeon makes an incision over the side of the thigh and removes the diseased or damaged bone and cartilage from the hip joint. Next, the surgeon replaces the head of the femur and acetabulum with new, artificial parts. Surgeons try to perform hip replacement with the smallest incision possible to try to limit the amount of injury to the soft tissues and bone.

The main parts of most hip replacements that fit against the bone, the socket, and the stem are made of metal. The joint surface (called the bearing surface) may have metal, ceramic, or plastic components. Your surgeon may use a combination of artificial pieces to replace the hip joint. For example:

A metal ball with a plastic socket lining.
A ceramic ball with a plastic socket lining.
A ceramic ball with a ceramic socket or lining.
Because of complications that may develop, surgeons rarely use metal-on-metal artificial bearing surfaces.

In addition, the surgeon will choose pieces that attach differently to the remaining bone, including:

Cemented replacements, which fasten artificial parts to healthy bone with a special glue or cement.
Uncemented replacements, use artificial parts with a porous surface or other types of surfaces. This allows the bone to grow into the pores to hold the new parts in place. Because it takes some time for the natural bone to grow and attach to the prosthesis, your activity may be limited for several months after surgery.
Hybrid replacements, use a cemented femur part and an uncemented acetabular part.
