- MRI is highly sensitive and specific for diagnosing ONFH, detecting subchondral fractures better than plain radiography.
- Core decompression plus bone marrow concentrate may reduce femoral head collapse risk compared to core decompression alone over ≤5 years.
- Vascularized bone grafting shows lower collapse rates than non-vascularized grafting in early-stage ONFH.
- Evidence is limited and observational, with inconsistent outcome reporting and a need for high-quality comparative studies.
