Callus Location and Management in Flatfoot Deformity

Clinical Recognition and Diagnosis

Pain under the medial midfoot combined with visible callus formation strongly suggests flatfoot-related mechanical overload, characterized by hard, thickened, yellowish areas at characteristic pressure points 1

Professional debridement of calluses by a trained healthcare provider is recommended to reduce plantar pressure and prevent complications, as suggested by the American Diabetes Association and other clinical guidelines 2, 1
Addressing underlying biomechanics with custom-made insoles or orthotic devices is essential to redistribute pressure away from the collapsed arch and prevent callus recurrence, according to clinical guidelines from the American College of Foot and Ankle Surgeons 1
Footwear modifications, including properly fitting shoes with adequate arch support, can help reduce abnormal pressure distribution and are recommended by the American Podiatric Medical Association 2, 1
The American College of Foot and Ankle Surgeons recommends not treating calluses in isolation without addressing the underlying flatfoot deformity, as repeated debridement without mechanical correction can lead to rapid recurrence and continued pain 1
