Hip Preservation Surgery by Core Decompression with BMAC for AVN Core decompression with bone marrow aspirate concentrate (BMAC) is a joint-saving surgery for early-stage avascular necrosis (AVN) of the hip, involving bone marrow harvesting, pressure-relieving drilling, and stem cell injection. How the Procedure Works Harvesting BMAC: Doctors take a small amount of bone marrow, usually from your hip bone (iliac crest), and spin it in a machine to concentrate healing stem cells. Core Decompression: The surgeon makes a tiny cut and uses an X-ray guide to drill one or more small holes into the dead bone area of the femoral head. Relieving Pressure: Drilling lowers high pressure inside the bone and helps new blood vessels grow to feed the joint. Injecting Concentrated Cells: The concentrated BMAC is injected right into the drilled channel to help the damaged bone heal and rebuild. Jul 31, 2026 Call now
