This is typically secondary to abnormal femur anatomy (CAM lesion). Hip impingement typically affects young men in their 20’s, often in patients who are active in sports. Hip impingement (and labral tears) may also result in pain in the hip area. The direct anterior approach may also not be suitable in very obese patients, particularly in patients where the stomach rests over the top of the thigh (where the incision is made). The direct anterior approach is generally an option for any type of arthritis, although in patients with abnormal anatomy (e.g., hip dyplasia, post-traumatic arthritis) is may not be suitable. Other causes of hip arthritis include hip dysplasia, post-traumatic arthritis, hip impingement, and rarely, infection. The most common causes of avasular necrosis of the hip are chronic steroid use (e.g., prednisone), alcohol abuse, and trauma. Rheumatoid arthritis is an example of an inflammatory arthritis, wherein the lining of the joint (synovium) becomes inflamed and thickened, resulting in direct damage to the cartilage.Īvasular necrosis of the hip is a condition which results in the bone underneath the cartilage losing its blood supply and collapsing (resulting in the overlying cartilage becoming damaged). The most common form of arthritis is degenerative arthritis (or osteoarthritis) which is secondary to a combination of genetics, possible "wear and tear", and age. Hip arthritis may occur because of many reasons, although the end result (thinning or failure of the cartilage) is the common final pathway. In 10% of patients, pain may may isolated to the side of the hip or the buttock.Īrthritis of the hip is unfortunately a progressive problem, although this rate of progression is variable and difficult to predict. Hip arthritis presents with pain in the groin approximately 90% of the time. This increase in friction may also cause stiffness around the joint, swelling, inflammation, and even instability and falls. When the cartilage wears away, the bone is forced to rub against the bone in order to move, which can be an extremely painful condition. The cartilage is a protective surface which functions as a "cushion" or padding, allowing the bones of the hip joint to move smoothly and normally against each other without friction. The hip joint is made up of a ball (femoral head) and socket (acetabulum) Review of the Condition Characteristics of hip arthritisĪrthritis of the hip is a condition in which the cartilage of the hip joint thins or wears away with time. This allows patients to return to normal daily activities shortly after surgery with a reduced risk of dislocation. Because the tendons aren’t detached from the hip during direct anterior hip replacement, hip precautions are typically not necessary. This approach often results in quicker recovery, less pain, and more normal function after hip replacement. This approach involves a 3 to 4 inch incision on the front of the hip that allows the joint to be replaced by moving muscles aside along their natural tissue planes, without detaching any tendons. Hip precautions after surgery (no bending greater than 90 degrees, no crossing legs, no excessive rotation) are generally required for this reason.ĭirect anterior hip replacement is a minimally invasive surgical technique. Failure of these muscles to heal after surgery may increase the risk of hip dislocation (the ball and socket separating), which is the leading cause of hip replacement failure. Detachment of these muscles may result in increased pain after surgery, and often prolongs the time to fully recover by months or even years.
Both techniques involve detachment of muscles and tendons from the hip in order to replace the joint.
Traditional hip replacement surgery involves making an incision on the side of the hip (lateral approach) or the back of the hip (posterior approach).
