[STEROID-INDUCED OSTEONECROSES OF FEMORAL HEAD]

Area of Science:

• Orthopedics
• Regenerative Medicine
• Radiology

Background:

• Avascular necrosis of the femoral head (ONFH) is a progressive disease leading to severe coxarthrosis.
• Steroid use is a primary cause of non-traumatic osteonecrosis, involving mechanisms like fat cell hypertrophy and intravascular coagulation.
• Early diagnosis via MRI is crucial for joint-preserving interventions, though specific biomarkers are lacking.

Purpose of the Study:

• To present a clinical case of steroid-induced avascular necrosis of the femoral head.
• To evaluate the effectiveness of total hip replacement in treating advanced stages of this condition.
• To highlight the importance of a multidisciplinary approach in managing ONFH.

Main Methods:

• Review of a clinical case of steroid-induced avascular necrosis of the femoral head.
• Magnetic Resonance Imaging (MRI) for early diagnosis.
• Total hip replacement surgery for late-stage disease and failure of joint-preserving procedures.

Main Results:

• The presented case of steroid-induced avascular necrosis of the femoral head achieved a positive clinical outcome.
• The patient experienced full physical and social rehabilitation following total hip replacement.
• Total hip replacement demonstrated effectiveness in treating this pathology, even in advanced stages.

Conclusions:

• Total hip replacement is an effective treatment for steroid-induced avascular necrosis of the femoral head, especially in late stages.
• Successful treatment leads to full patient rehabilitation and restoration of function.
• While joint preservation is ideal, hip replacement remains a viable and effective option when conservative measures fail or the condition is advanced.
