Description

(See anatomy) Under-run heel is a specific form of double sole involving only the heel region.

The sole is detached from the claw around the coronary region of the bulb. The sole at this point can easily be peeled forward.

Cause

Unlike a double sole the under-run heel is caused by trauma such as a penetrating foreign body. This condition is caused by the presence of pus or other fluid between the sole and the tissues below.

Treatment

Treatment is similar to that of double sole. The loose horn should be carefully pared away.

Care must be taken to leave part of the wall at the heel to bear weight. It will take several days for the exposed sole to harden.

Control

As this is only an occasional accident, control measures cannot be described.
