Bone and Joint Diseases

Osteonecrosis of the femoral head occurs when blood supply to the ball of the hip joint is disrupted, causing bone tissue to die and, if untreated, leading to collapse of the joint and severe disability. Researchers study how factors such as prolonged glucocorticoid use, alcohol, and clotting disorders compromise the bone's microcirculation, and how bone marrow changes detectable by MRI can signal the disease before structural damage becomes irreversible. Current treatment strategies range from core decompression — drilling into the affected bone to relieve pressure and stimulate healing — to emerging stem cell therapies that aim to restore the local cellular environment and prevent progression. Key open questions center on why only some high-risk patients develop the condition and whether cell-based or biological interventions can reliably halt disease progression in early-stage cases.
