What Researchers Did
Researchers reviewed the current understanding of the pathogenesis, diagnosis, and management of osteoradionecrosis of the femoral head.
What They Found
They found that osteoradionecrosis (ORN) of the femoral head is increasing due to advances in radiation therapy and improved cancer survival, with a complex pathogenesis involving vascular injury, stem cell injury, and bone loss. Diagnosis is challenging, requiring consideration of radiation exposure, clinical signs, and imaging, while effective treatments include hyperbaric oxygen therapy, total hip arthroplasty, and Girdlestone resection arthroplasty.
What This Means for Canadian Patients
Canadian patients undergoing radiation therapy for cancer should be aware of the potential risk of osteoradionecrosis of the femoral head, which can cause significant hip pain and dysfunction. Early and accurate diagnosis, considering radiation history and imaging, is crucial for timely intervention with treatments like hyperbaric oxygen therapy or hip surgery to improve outcomes.
Canadian Relevance

Study Limitations
A key limitation is the incomplete literature and lack of a criterion standard or clear consensus on the management of osteoradionecrosis of the femoral head.
