Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Yes, avascular necrosis is commonly encountered in the hip. This condition is usually caused by: • Long-term use of corticosteroid • History of transplant • Bisphosphonates use (especially on the jaw) Early diagnosis and treatment are needed to prevent joint destruction or hip replacement. The therapy that usually chosen are: • Core decompression • Removing part of the inner layer of your bone • Bone transplant (graft). This procedure can help strengthen the area of bone affected by avascular necrosis. • Bone reshaping (osteotomy) • Joint replacement • Regenerative medicine treatment You can discuss it with your treating doctor. Also, for the possibility of walk better do it as soon as possible. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nurul Falah
