![]() ![]() ![]() Multiple dislocations are infrequent, but in patients who have suffered multiple hip dislocations, the orthopedic surgeon may recommend revision surgery. X-ray of a dislocated total hip replacement prosthesis showing the ball forced out of the socketĪnyone with a replaced hip who has suffered a hip dislocation is then predisposed to have them again, because the dislocated ball disrupts the important muscles and ligaments around the hip. This can include elderly and debilitated patients, or those who got a hip replacement after haiving a hip fracture or multiple prior hip surgeries. However, some people are predisposed to this complication. This condition is called a dislocated hip or hip dislocation.ĭislocations in people who have had a hip replacement are relatively infrequent, particularly in the healthy patient who carefully follows precautions given by their surgeon and physical therapist. However, trauma or certain hip positions can force the hip ball out of the socket. A hip replacement is designed to have a large range of motion. Two key factors keep the ball inside the socket: (1) the alignment and fit of the ball and the socket, and (2) forces generated by the strong muscles and ligaments around the hip joint. For a hip replacement to function well, the ball must remain inside the socket at all times. mechanical failure (implant wear and tear – loosening or breakage)Īs mentioned above, a hip replacement implant's structure resembles that of the natural hip (a ball and socket).repetitive (recurrent) dislocation of a hip replacement.1 The most common reasons for revision are: In the United States, there are approximately 18 revision hip replacements performed for every 100 hip replacements. Hip revision operations are performed relatively infrequently. (Find hip revision surgeons at HSS to suit your specific condition, location and insurance.) What are the key reasons for hip revision surgery? A preoperative aspiration (fluid sample) and/or special blood work may be needed if the surgeon suspects an infection in the failed hip. Often, special radiographic ( X-ray) projections, CT scan, MRI or EOS imaging of the hip may be necessary to determine position and fixation of the replacement parts (components), and to determine precisely the extent of bone loss around a failed implant. Preoperative investigations of patients who will undergo revision surgery are more extensive than those for patients who will undergo a primary surgery. However, some patients may need one or more revisions of a hip replacement, particularly if the initial hip replacement surgery is performed at a young age and the patient chooses to have a very active physical lifestyle. The majority of elderly patients who receive a hip replacement retain the prosthesis for 15 to 20 years, and sometimes for life.
