Hip replacement - Wikipedia, the free encyclopedia In this X-ray, the patient’s right hip (on the left in the photograph) has been replaced, with the “ball” of this ball-and-socket joint replaced by a metal head that is set in the thighbone or femur and the socket replaced by a white plastic cup (clear in this X-ray). Hip replacement is a medical procedure in which the hip joint is replaced by a synthetic implant. The main complications of hip arthroplasty (replacement) are wear of the polyethylene liner, loosening of the joint components, and infection of the joint. en.wikipedia.org /wiki/Hip_replacement   (984 words)

Hip Replacement Hip replacement, or arthroplasty, is a surgical procedure in which the diseased parts of the hip joint are removed and replaced with new, artificial parts. During hip replacement, the surgeon removes the diseased bone tissue and cartilage from the hip joint. The most common later complication of hip replacement surgery is an inflammatory reaction to tiny particles that gradually wear off of the artificial joint surfaces and are absorbed by the surrounding tissues. www.drbathaw.com /hip.htm   (2218 words)

The Steadman-Hawkins Clinic Hip arthritis is a degenerative condition that affects the hip joint, and often leads to a significant impairment in the quality of life. The stability of the hip joint is maintained by the precise fit of the femoral head within the acetabulum. Hip arthritis is any condition that leads to degeneration of the hip joint and its cartilage surfaces. www.steadman-hawkins.com /hip/overview.asp   (603 words)

MedlinePlus Medical Encyclopedia: Hip joint replacement This surgery is performed to replace all or part of the hip joint with an artificial device (a prosthesis).

HIP REPLACEMENT -- Arthritis Hip Surgery Info - Hip Replacement The modern Hip Replacement was invented in 1962 by Sir John Charnley, an orthopedic surgeon working in a small country hospital in England. The major long-term problems with hip replacements are wearing out of the socket, and loosening of the bond between the implant and the bone. The hip joint can be approached from the front of the hip (anterior approach), from the back (posterior approach), from the side (trans-trochanteric approach), from midway between front and side (antero-lateral approach), or through a two incision approach (one anterior, and one posterior). www.hipsandknees.com /hip/hipsurgery.htm   (1244 words)

Hip Replacement Surgery : Hip joint replacement solutions Hip replacement surgery removes the arthritic ball of the upper femur (thighbone) as well as the damaged cartilage from the hip socket. In total hip joint replacement, the femoral component can be secured to your body in one of two ways: using bone cement as a grout to affix the components to your bone, or using a "cementless" component that is specially designed to allow your own bone to grow into the surface of the implant. In the case of the hip, it is where the head of the femoral component meets the acetabular socket. www.biomet.com /patients/hip_replacement.cfm   (1431 words)

Hip Replacement at the Center for Total Joint Replacement Hip replacement surgery involves replacing the stem (long part of the bone) and head of the femur and the acetabular "cup" with prosthetic components. Hip replacement surgery is done through an incision about 6 to 12 cm (2 to 5 inches) in length, which is later closed with sutures or staples. Patients with cemented hip replacements can put pressure on the leg right away, while those with ingrowth replacements need to allow about 6 weeks for the bone to grow in and be more protected. www.pamf.org /joints/procedures/hip.html   (382 words)

Rothman Institute Orthopaedics: The Hip The hip is a ball and socket joint that acts much like a ball bearing, allowing you to turn in different directions while supporting the body. Cemented total hip replacement uses cement to secure an implant to the bone, while with cementless technology the bone heals directly to the prosthesis. Theoretically, cementless hip replacements should have a longer lifetime and are desirable in patients who have good enough bone quality to accommodate a cementless implant. rothmaninstitute.com /patienteducation/joint/hip/index.html   (1381 words)

New Alternative to Hip Replacement It is this neck length and angle that determines the natural length of a patient's leg after surgery, and since it is not removed and replaced with an artificial device during the resurfacing procedure, there is a greater likelihood of maintaining accurate leg length. While the implant closely matches the size of a patient's natural femoral head (hip ball), it is substantially larger than the femoral head of a traditional total hip replacement implant.

Questions and Answers about Hip Replacement   (Site not responding. Last check: 2007-11-03) Hip replacement may be problematic for people with some health problems, regardless of their age. During a traditional hip replacement, which lasts from 1 to 2 hours, the surgeon makes a 6- to 8-inch incision over the side of the hip through the muscles and removes the diseased bone tissue and cartilage from the hip joint, while leaving the healthy parts of the joint intact. However, because more people are having hip replacements at a younger age, and wearing away of the joint surface becomes a problem after 15 to 20 years, replacement of an artificial joint, which is also known as revision surgery, is becoming more common. www.niams.nih.gov /hi/topics/hip/hiprepqa.htm   (3095 words)

Hip Replacement To duplicate this action, a total hip replacement implant has three parts: the stem, which fits into the femur and provides stability; the ball, which replaces the spherical head of the femur; and the cup, which replaces the worn-out hip socket. In most cases, the pelvic socket is left intact and the head of the femur is replaced, using a component similar to those of a total hip replacement. The operation is sometimes performed for other problems such as hip fractures or aseptic necrosis (a condition in which the bone of the hip ball dies). www.dhmc.org /ortho/hip/Hip_Implants.html   (695 words)
