Principles of Bone Grafting for Osteonecrosis of the Hip
摘要
Osteonecrosis of the femoral head (ONFH) is a disease that mainly affects patients in the third and fourth decades of life, which often leads to femoral head collapse and subsequent destruction of the hip joint [1, 2]. Depending on the time of insult and the stage of osteonecrosis, many therapeutic options are available such as core decompression, rotational osteotomy, bone grafting, resurfacing of the femoral head, and total hip arthroplasty [3].
