Answer

Sensory neuropathy involving the feet may lead to unrecognized episodes of trauma caused by ill-fitting shoes. This is compounded by motor neuropathy causing intrinsic muscle weakness and splaying of the foot on weight bearing. The result is a convex foot with a rocker-bottom appearance. Multiple fractures go unnoticed, until bone and joint deformities become marked. This is termed a Charcot foot (ie, neuropathic osteoarthropathy) and is observed most commonly in people with diabetes mellitus, affecting approximately 2% of persons with diabetes.
