Idiopathic osteonecrosis (IO) of the femoral head in adults is a serious disease that leads to permanent disability at the most working age (in the 3-5th decade of life). Its essence lies in subchondral necrosis of the bone matter of the head in the upper, most loaded segment, followed by impaction of the head and the development of the most severe deforming arthrosis. The disease develops spontaneously, for no apparent reason, and should be distinguished from post-traumatic head necrosis after neck fractures and hip dislocations.
