Which condition is often a precursor to plantar ulcer formation?

Callusing is often a precursor to plantar ulcer formation because it indicates areas of increased pressure or friction on the foot. When the skin thickens in response to these pressures, it can lead to a loss of the underlying protective layers, making the skin more susceptible to breakdown.

As calluses develop, they may not provide adequate sensation or protection against further trauma, which increases the risk of skin integrity being compromised. If a callused area experiences continuous pressure, it may eventually lead to skin ulceration. This can be particularly concerning for individuals with conditions like diabetes, where healing capabilities are diminished and the risk of infection is heightened.

Understanding this process highlights the importance of monitoring and managing callus formation in patients, especially those at higher risk for foot ulcers. By addressing callusing early, practitioners can prevent the progression to more severe conditions such as plantar ulcers.
