 Early symptoms may include mildly painful limp, pain down the inner thigh to the knee, some restriction of hip movement, pain at extremes of movement, and tenderness over the hip joint. Treatment may include a brief period of bed rest (1 to 3 days) followed by bracing. Rarely bracing may be required for 2 to 3 years. Chance of recovery (prognosis) varies, but tends to be better for younger patients (e.g., less than 6 years of age). Some people with this syndrome go on to develop degenerative arthritis. The cause of the condition is unknown.Legg-Calve-Perthes disease occurs when the ball of the thighbone in the hip doesn’t get enough blood, causing the bone to die.
