Bone Marrow Aspirate
Bone marrow aspirate concentrate (BMAC) is a biologic product that is produced through the centrifugation of the patient’s own bone marrow. The bone marrow is typically harvested through the Iliac Crest which is just above the hip joint. The aspirate is obtained with a needle, and the resulting aspirate is then spun down in a centrifuge to concentrate the cells. This end product is rich in stem cells and growth factors. The BMAC can then be injected during a surgical procedure in the foot or ankle to increase healing rate. Typically, BMAC is used for non unions of fractures, difficult fusions, or healing of cartilage lesion in the ankle (osteochondral lesions of talus).
