Usually, a<unk>  causes groin pain, but it may cause pain in only the thigh or knee, because the pain may be referred along the distribution of the obturator nerve. The pain may occur on both sides of the body (bilaterally), as up to 40 percent of cases involve slippage on both sides. In cases of bilateral<unk> s, they typically occur within one year of each other. About 20 percent of all cases include a<unk>  on both sides at the time of presentation. Signs of a<unk>  include a waddling gait, decreased range of motion. Often the range of motion in the hip is restricted in internal rotation, abduction, and flexion. A person with a<unk>  may prefer to hold their hip in flexion and external rotation. Complications Failure to treat a<unk>  may lead to: death of bone tissue in the<unk>  head (avascular necrosis), degenerative hip disease (hip osteoarthritis), gait abnormalities and chronic pain.<unk>  is associated with a greater risk of arthritis of the hip joint later in life. 17–47 percent of acute cases of<unk>  lead to the death of bone tissue (osteonecrosis) effects.
