What Is Bone Marrow Edema of the Hip Joint?

Bone marrow edema of the hip joint occurs when the bone marrow inside the hip bone becomes inflamed and filled with fluid, explains the American Academy of Orthopaedic Surgeons. A hip bone with bone marrow edema appears bright white on an MRI scan of the joint. Bone marrow edema is a common indicator of transient osteoporosis of the hip. Other potential causes of bone marrow edema include fractures, bone tumors, bone bruises and ligament injuries, notes Robert J. Daley, M.D.
