Diabetic Foot Ulcers Can Spread to Bone, Doctor Warns
A small foot wound can become dangerous for someone with diabetes.
This is because nerve damage may stop the person from feeling the injury.
Poor blood flow and high blood sugar can also slow healing and weaken the body’s response to infection.
The infection can move from the skin into deeper tissues and then into the bone.
Bone infection is called osteomyelitis.
Redness, swelling, pus, bad smell, dark tissue or a wound that gets deeper are warning signs.
Fever may be missing even when the infection is serious.
Doctors can use examinations, X-rays, blood tests and sometimes an MRI to check the bone.
Some infections can be treated with antibiotics, but severe cases may need surgery to protect the foot or the person’s life.
An infected diabetic foot ulcer can spread from the skin through deeper tissues and eventually reach the bone, causing osteomyelitis.
Neuropathy, poor circulation and high blood sugar can make foot injuries harder to notice, heal and fight off infection.
Warning signs include increasing redness, warmth, swelling, discharge, foul odour, tissue death, a deeper ulcer or visible bone.
Doctors may use a probe-to-bone test, X-rays and inflammatory blood markers; MRI may be needed because early X-rays can appear normal.
Selected forefoot bone infections may respond to about six weeks of antibiotics, while severe infections, abscesses, gangrene or poor blood flow may require surgery.
- Who
- People with diabetes who develop infected foot ulcers, with guidance from Dr Rajiv Kovil, a Diabetes and Obesity Specialist at Zandra Healthcare.
- What
- An infected diabetic foot ulcer can spread to the bone and cause osteomyelitis, a serious complication that may require antibiotics or surgery.
- Where
- The infection may spread from a foot ulcer through the skin, soft tissues, joints and into the foot bones.
- When
- The infection can progress when an ulcer is deep, longstanding or not promptly treated.
- Why
- Diabetic neuropathy, poor circulation and high blood sugar can make injuries harder to notice, slow healing and impair the body’s response to infection.
Key facts
- Bone infection
- Osteomyelitis is an infection of the bone that can result from an infected diabetic foot ulcer.
- Warning signs
- Redness, warmth, swelling, pus, foul odour, increasing wound depth, dark tissue or visible bone.
- Important limitation
- Fever and chills may be absent even when a diabetic foot infection is significant.
- Initial assessment
- Doctors may combine examination, a probe-to-bone test, a plain X-ray and inflammatory markers such as ESR or CRP.
- Advanced imaging
- MRI is the preferred advanced imaging test when the diagnosis remains uncertain.
- Antibiotic treatment
- Selected cases may be treated without bone removal using about six weeks of appropriate systemic antibiotics.
- Surgery
- Surgery may be needed for dead or extensively infected tissue, abscesses, gangrene, severe infection or significant ischaemia.

“Blood supply must always be assessed; where circulation is inadequate, vascular assessment and sometimes revascularisation are crucial.”
