Abstract:

Osteonecrosis of the femoral head (ONFH) is a necrosis of bone tissue caused by interrupted blood supply, often leading to femoral head collapse and loss of hip joint function. For young patients, hip preservation surgery has become an important option as it reduces the risk of hip replacement surgery and functional limitations. In recent years, bone morphogenetic protein 2 (BMP2) has gradually become an innovative strategy for treating femoral head necrosis due to its key role in bone formation. BMP2 can promote osteogenesis and angiogenesis, significantly enhancing the effectiveness of hip preservation treatment for femoral head necrosis when combined with bone repair materials through local delivery systems. When used in conjunction with quadratus femoris muscle-bone flap transplantation, BMP2 has demonstrated unique advantages in accelerating bone regeneration and improving surgical efficacy, providing strong support for emerging treatment methods.

Key words: Femur head necrosis, Hip, Bone morphogenetic protein 2
