Once AVN has progressed to advanced osteoarthritis, the disease is considered irreversible and typical requires a hip replacement. This condition may happen in any bone. The foveal artery runs within the ligament, though its contribution is only significant in pediatric populations. It happens most commonly in the ends of a long bone. [10], Bisphosphonates, such as alendronate, prevent osteoclasts action thus reducing bone resorption. If AVN is left untreated, the bone can collapse. Treasure Island (FL): StatPearls Publishing; 2022 Jan. Most of the blood supply of the femoral head comes from the lateral femoral circumflex artery, which gives rise to three or four retinacular vessels which supply the cartilaginous border of the head. .
