Coral-inspired scaffold enhances bone repair by reprogramming immune cells

SONFH is one of the leading causes of non-traumatic osteonecrosis. Reported in up to 9%–40% of patients receiving prolonged or high-dose glucocorticoid therapy, the condition progressively weakens the femoral head and can eventually lead to joint collapse, making effective bone repair a major clinical challenge.
