Purpose:
The study aims to assess the effect of hyperbaric oxygen therapy (HBOT) on the radiological and clinical outcomes in patients with early Osteonecrosis of the femoral head (ONFH) at mid-term follow-up.
Methods:
A prospective observational study was conducted on patients with Osteonecrosis of the femoral head (ONFH). ONFH was diagnosed based on plain radiographs and MRI of the bilateral hips. ARCO stages 1-3A of ONFH patients were included with non-traumatic etiologies. Each patient received 5 sessions of HBOT per week for a total of 35 sessions. Repeat MRI was done within 6 weeks of completion of HBOT sessions, at 1 year and 2 years of follow-up. The pre-treatment and last follow-up (2 years) clinical (Harris Hip Scores, VAS Scores) and radiological parameters (JIC Classification, ARCO Staging, Modified Kerboul Angle, Bone marrow edema severity) were compared.
Results:
At the final follow-up, there was a significant improvement in the mean Harris Hip Score (p = 0.001) and VAS Score (p = 0.001). There was also a significant improvement in the JIC classification (p = 0.03), Modified Kerboul Angle (p = 0.001) and Bone marrow edema grading (p = 0.001) at the final follow-up.
Conclusions:
HBOT provides good clinical and radiological improvement and is an effective, safe, and non-invasive treatment for patients in the early stages of ONFH. Its role in the early collapse stage needs further validation by higher-level, prospective, large-scale RCTs.
