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.
Avascular necrosis is the death of bone tissue due to a lack of blood supply.
