What Researchers Did
Researchers studied 12 patients with early-stage avascular necrosis (AVN) of the femoral head, giving each daily hyperbaric oxygen therapy for 100 days.
What They Found
Overall, 81% of patients who received hyperbaric oxygen therapy showed a return to normal on MRI, significantly higher than the 17% observed in a previously studied untreated group. This suggests hyperbaric oxygen is effective for treating stage-I AVN of the femoral head.
What This Means for Canadian Patients
For Canadian patients diagnosed with early-stage avascular necrosis of the femoral head, this study suggests that hyperbaric oxygen therapy could be an effective treatment option to help restore normal bone health. This may offer a non-surgical approach to prevent disease progression for some individuals.
Canadian Relevance
No direct Canadian connection identified. Avascular necrosis is not a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
The study involved a small number of patients (12) and focused only on a very specific stage (Steinberg stage-I) and size of avascular necrosis lesions.
