The most common treatment for a dislocated hip after hip replacement is a closed reduction, according to the American Academy of Orthopaedic Surgeons. During closed reduction, the doctor physically guides the ball of the implant back into the socket, NYU Langone Medical Center explains.
Dislocations after hip replacement occur infrequently, states AAOS. They tend to show up within a few months of the surgery while the tissues are recovering. Patients often must learn to move and bend differently to prevent dislocation.
To prevent dislocation, patients should not bend over at an angle greater than 90 degrees, Mayo Clinic warns. Legs should not go past the middle of the body. Pulling the knees to the chest offers the greatest chance of dislocation, reports the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Another operation is often needed if the implant dislodges repeatedly.
Many factors contribute to hip dislocation. Patients 85 years old and above or individuals with Parkinson's disease are at greater risk, reveals About.com. Ball-and-socket replacements that have relatively smaller balls are more likely to dislocate. The surgeon's experience with the procedure plays a large role as well. Patients are much more likely to suffer dislocations if their surgeons perform fewer than five hip replacements annually.
