Neuropathic Foot Ulcers
Neuropathic ulcers develop when repetitive loading injures a foot that cannot reliably feel warning pain. Diabetes is a common cause, but neuropathy can arise from other conditions as well.
01
The mechanism
Loss of protective sensation allows repetitive pressure, friction or a foreign object in the shoe to injure tissue without a normal pain response. Deformity and callus can concentrate load even further.
02
Evaluation
The wound is assessed together with sensation, deformity, callus, footwear, gait, pressure points, infection and arterial perfusion. Neuropathy does not protect against ischemia; both can coexist.
03
Treatment framework
Effective pressure redistribution is central. Local wound care, callus management, debridement when appropriate, infection treatment, vascular evaluation and footwear modification may be required. Once healed, prevention focuses on surveillance, protective footwear and reducing recurrent high-pressure loading.
04
Surgical considerations
Selected patients may benefit from correction of deformity or tendon imbalance when these create focal pressure that cannot otherwise be controlled. Deep infection, bone involvement or soft-tissue loss may require more extensive surgical management.
Common questions
Questions about neuropathic foot ulcers
These are general educational answers. Diagnosis and treatment require direct clinical assessment.
Can a neuropathic ulcer occur without diabetes?
Yes. Any condition that significantly reduces protective sensation can increase the risk of pressure-related skin breakdown.
Why is callus important?
Callus often marks an area of concentrated pressure. Thick callus can also increase local tissue stress and hide the true dimensions of an ulcer.
Should I walk on a neuropathic ulcer if it does not hurt?
Lack of pain is part of the problem. Weight-bearing may continue to traumatize the wound. The appropriate level of activity and off-loading device should be determined clinically.
What is Charcot foot?
Charcot neuroarthropathy is a destructive process affecting bones and joints in a neuropathic foot. Acute warmth, swelling or deformity deserves prompt assessment.
How are recurrences prevented?
Regular foot surveillance, protective footwear, callus management, pressure redistribution and prompt attention to new skin changes are key components of prevention.
