[Advances in biomechanical studies on osteonecrosis of the femoral head]

Osteonecrosis of the femoral head is a common clinical orthopedic disease. The progression of the disease is rapid and the prognosis is poor. All the medical profession recognize it as one of the unresolved medical problems. Biomechanical factors play an important role in the course of progression and treatment of osteonecrosis of the femoral head. In this paper, we review the literature and introduce the advanced biomechanical studies on the symptoms, image, collapse, collapse prediction, preserving femoral head surgery of osteonecrosis of the femoral head.
