What Researchers Did
Researchers retrospectively analyzed MRI scans from 20 children with aseptic osteonecrosis during chemotherapy to evaluate the effect of hyperbaric oxygen therapy.
What They Found
Initially, the hyperbaric oxygen therapy group (Gr. II, n=12) had more severe findings with an average MRI score of 3.4 compared to the control group (Gr. I, n=8) with 2.65. Over time, average scores increased to 3.2 in Gr. I and 4.1 in Gr. II, indicating progression, with no statistically significant difference between the groups.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in Germany.
Study Limitations
Limitations include the retrospective design, small sample size, and initial differences in disease severity between the treatment groups.
