[Bilateral non-traumatic caput femoris osteonecrosis in a healthy 45-year-old woman]

In this case report, a 45-year-old woman with no major risk factors for non-traumatic caput femoris osteonecrosis (ACFN) presented with severe bilateral hip pain and limited mobility. Previously healthy without excessive alcohol consumption, her only relevant history included intermittent corticosteroid injections for allergies during adolescence. Diagnostic imaging revealed joint deterioration and ACFN. She ultimately required bilateral total hip arthroplasty with positive results. This case underscores the importance of early diagnosis and treatment of ACFN.
