Nails & Corns

Nails & Corns

Skin and nails show change with increasing age. Nails are subject to superior, lateral and frontal pressure from the shoes therefore constant low level trauma to sudden severe trauma such as dropping a heavy object on the toes or stabbing them will alter the normal morphology leading to many deformities of the nails.

Skin also loses its elasticity and tensile strength with age, especially under the foot which is subject to pressure of ground reaction force, friction and shearing force leading to formation of hard skin (callus) i.e. hard, dense, yellowish in colour plaques of hyperkeratosis or with constant and prolonged pressure to form a corn which is darker, harder usually with central focal point either alone or within a callus plaque.
