Hyperbaric oxygen therapy involves breathing nearly 100% oxygen at increased atmospheric pressure to markedly increase plasma and tissue oxygen levels. In orthopaedics, it is mainly used as an adjunct in chronic refractory osteomyelitis, severe crush injuries, acute traumatic ischaemia, compromised flaps or grafts, selected early osteonecrosis and certain severe infections or radiation-related tissue injuries. Its effects include improved tissue oxygenation, reduction of oedema, enhanced leukocyte bacterial killing, angiogenesis and support of fibroblast and collagen activity. HBOT should never replace definitive treatment such as debridement, antibiotics, fracture stabilisation, revascularisation or fasciotomy. Patient selection is important because the evidence and benefit vary by indication, and untreated pneumothorax remains the classic major contraindication.
