Purpose: To compare the use of hyperbaric oxygen (HBO) and non-weight bearing in the treatment of Stage I avascular necrosis of the femur head (AVNHF) with treatment by non-weight bearing (NWB) only.

Methods: Vande Berg et al.’s (1) criteria for irreversibility of sub-chondral lesions assessed for thickness and length in AVNFH grade I were used to compare 16 AVN hips treated by HBO with Vande Berg et al.’s group treated by NWB only. 15 hips were "Idiopathic" AVNFH and 1 hip was in a steroid treated Lupus Erythematosus. Only AVNFH grade I was included: cases of bone marrow edema only or transient osteoporosis were strictly excluded as were higher grades of AVNFH.

Results: Irreversibility likelihood was 88% for thickness of lesion for the control group and 10% for the HBO group. For lesion length irreversibility likelihood was 73% in the controls as compared to 0% in the HBO treated group. Altogether the HBO group registered > 90% total resolution or reduction in size of the sub-chondral lesions (15 hips). The single failure was in the steroid treated Lupus case.

Conclusions: HBO treatment is highly effective in Idiopathic Stage I AVNFH.

For those interested in receiving HBOT that may have difficulty with financing the treatments, we have people that can give advice on fund-raising. The previous case studies are only a glimpse of the hundreds of people which have received HBOT at the Richmond Hyperbaric Center for a variety of conditions with favorable outcomes. Please contact us for more information on a particular condition which may benefit from hyperbaric oxygen therapy.

The Richmond Hyperbaric Health Center has engaged in scientific research projects including a pilot study on the treatment of RSD/CRPS. We would like to pursue future research studies as well and are open to any inquiries about the use of  HBOT  for researching various conditions.
