Many patients recover from core decompression surgery within a few weeks, notes Emory Healthcare. Recovery time takes substantially longer when the patient requires a bone graft alongside the core decompression surgery.
Surgeons perform core decompression surgery to treat avascular necrosis, or osteonecrosis of the femoral head, states Emory Healthcare. Health care professionals suggest core decompression when crutches fail to relieve pressure in the hip.
While total hip replacement surgery is required for advanced stages of the condition, core decompression surgery is a viable treatment method when osteonecrosis is detected early, reports About Joints. Core decompression consists of drilling a hole into the diseased bone to relieve pressure, which slows down or stops progression of the disease.
