Effect of HBOT on Femoral Head Avascular Necrosis (AVN)

Effect of Hyperbaric Oxygen Therapy on Osteonecrosis of the Femoral Head When Combined With 3D Navigated Core Decompression With Bone Marrow Aspirate Concentrate

The primary objective of this study is to determine whether the Hyperbaric Oxygen Therapy (HBOT) conducted under the Marx Protocol improves pain outcomes when combined with core decompression with autologous bone marrow aspirate concentrate to treat patients with femoral head avascular necrosis.

Inclusion Criteria:

• Provision of signed and dated informed consent form
• Stated willingness to comply with all study procedures and availability for the duration of the study
• Diagnosed with femoral head avascular necrosis
• Enrolled into Yale Avascular Necrosis Program
• Avascular necrosis lesion is classified as ARCO I or ARCO II by Investigator
• Surgical Candidate for Core Decompression using 3D image guidance with bone marrow aspirate concentrate

Exclusion Criteria:

• Hip has already collapsed due to severe avascular necrosis (ARCO III or ARCO IV)
• Medical comorbidities that prevent them from being a surgical candidate (example: obesity)
• Absolute contraindications to HBOT, including severe decompensated cardiac failure or lung disease putting them at high risk for pneumothorax
• Pregnant
• Prisoner
• Does not sign Informed Consent Form
