The pathogenesis of avascular necrosis of femoral head (AVNFH) has not been fully understood.[sup][1],[2],[3] The AVNFH typically presents in the young adults and will quickly progress to femoral head collapse and arthritic changes in the absence of treatments.[sup][4] Therefore, hip joint preservation surgery should be considered to prevent the collapse of the femoral head or at least postpone the need for a hip arthroplasty.[sup][3],[5] The interventions include core decompression, osteotomies, and nonvascularized or vascularized bone grafting.[sup][6] However, osteotomies and bone grafting can cause severe trauma, which further undermines the femoral head blood supply system and worsens the ischemic conditions in the femoral head.
