What Researchers Did
Researchers followed 23 male patients with avascular necrosis of the femoral head (osteonecrosis) through two 30-session cycles of HBOT at 2.5 ATA for 90 minutes each, measuring inflammatory markers and reactive oxygen species before and after treatment.
What They Found
TNF-alpha and IL-6 levels declined progressively over 60 HBOT sessions. These reductions in inflammatory markers mirrored improvements in bone marrow edema on imaging and decreases in self-reported pain by patients.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This uncontrolled cohort study had no comparison group; natural disease progression or other treatment factors may have contributed to the observed improvements.
