For those with a defective hip joint, hip replacement surgery can significantly increase mobility, improving quality of life. However, a small percentage of individuals who undergo this surgery experience hip arthroplasty dislocation. Anyone considering this procedure should learn to recognize the symptoms of a dislocated hip replacement, which can include pain, difficulty walking, and an apparent deformity in the leg. Once a dislocation has been recognized, it must be treated immediately so that full mobility can be restored. In addition, precautionary measures must be taken to reduce the chances of displacement.
A defective or over-extended hip joint prosthesis can become dislodged.
Hip replacement surgery is performed on people whose hip joint has stopped working properly, causing pain and difficulty walking. Several factors can cause hip function to be compromised, including arthritis, injury, a cyst or tumor, or a circulatory condition. Surgery involves removing the defective ball and socket joint followed by its replacement with a prosthetic joint, usually made of ceramic, porcelain, plastic, or a combination of these. After an initial period of recovery, hip replacement surgery typically significantly increases mobility and reduces hip pain.
Hip, buttock and thigh pain is common with hip replacement dislocation.
A small number of individuals who undergo this surgery, however, experience dislocation from hip arthroplasty. Dislocation usually refers to the movement of the ball component of the hip prosthesis out of the socket component. It most commonly affects those who have had their hip replaced less than six months ago, as the muscles and ligaments that normally support the hip are initially weakened by the procedure.
For those with a defective hip joint, hip replacement surgery can significantly increase mobility, improving quality of life.
Hip replacement dislocation symptoms may include a popping or popping sound at the time of dislocation. Pain in the hip, buttocks, and thigh is also common. It may be difficult or impossible to put pressure on the affected leg. Also, the affected leg may appear twisted outward or may appear shorter or longer than the other leg.
A person who has had hip replacement surgery may need physical therapy.
Individuals who experience any of these symptoms should see their doctor, who may perform an X-ray to confirm that the hip has indeed dislocated. Hip replacement dislocation can often be treated quite easily with a doctor simply guiding the displaced ball back into the socket. If this treatment is unsuccessful, however, further surgery may be necessary.
Hip dislocation is possible after hip replacement surgery.
Those who have had a hip replacement can take precautionary measures to reduce the chances of dislocation. First and foremost, they should avoid bending the hip more than 90 degrees, especially in the months immediately following surgery. Also, one should avoid sitting cross-legged and sleeping on one side.
