Osteomyelitis and HBOT: Treating Bone Infections When Antibiotics Aren't Enough

Osteomyelitis — infection of the bone — is one of the most challenging conditions in wound care. Bone infections can persist for months or years, resist multiple rounds of antibiotics, and lead to significant tissue loss if not adequately treated. At Elite Wound Care Center in Palm Harbor, we use hyperbaric oxygen therapy as a critical component of our osteomyelitis treatment protocol.

How Bone Infections Develop

Osteomyelitis most commonly develops when bacteria from an overlying wound penetrate through soft tissue and reach the bone. This is particularly common in diabetic foot ulcers, where deep infections can extend through tendons and ligaments directly into the bones of the foot. It can also occur after surgical procedures involving hardware implantation, through blood-borne spread from infections elsewhere in the body, or from open fractures where bone is exposed to the environment.

Once bacteria establish themselves in bone tissue, they are extremely difficult to eradicate. Bone has a relatively limited blood supply compared to soft tissue, which means antibiotics delivered through the bloodstream may not reach the infected area in sufficient concentrations to kill the bacteria. Additionally, bacteria can form biofilms on bone surfaces — protective communities that are highly resistant to both antibiotics and immune system attack.

The Standard Treatment Approach

Treatment of osteomyelitis typically requires a combination of surgical debridement to remove infected and dead bone tissue, prolonged intravenous antibiotic therapy lasting four to six weeks or longer, and careful wound management to protect the surgical site during healing. Even with aggressive treatment, recurrence rates for chronic osteomyelitis remain significant.

How HBOT Enhances Osteomyelitis Treatment

HBOT improves outcomes in osteomyelitis treatment through several mechanisms. The therapy increases oxygen levels in bone tissue to a degree that enhances the ability of osteoclasts — the cells responsible for removing dead bone — to function effectively. It also stimulates osteoblasts, the cells that build new bone, promoting bone regeneration in areas where infected tissue has been removed.

HBOT enhances antibiotic penetration into bone tissue by improving local blood flow and increasing the oxygen gradient across bacterial cell membranes. It strengthens the immune response within bone, where white blood cells often function poorly due to the naturally lower oxygen environment.

Clinical studies have demonstrated that adding HBOT to standard osteomyelitis treatment reduces the recurrence rate and improves the likelihood of limb salvage in cases where amputation might otherwise be considered.

What to Expect During Treatment

Osteomyelitis treatment with HBOT typically involves 40 or more sessions delivered five days per week alongside surgical management and antibiotic therapy. Progress is monitored through regular imaging studies and laboratory tests. The treatment can be demanding, but the alternative — chronic infection, repeated surgeries, or amputation — makes the investment worthwhile.
