Kohler disease

Overview

Type of disease: Rare conditions

Kohler disease is a condition that involves a bone at the arch of the foot called the tarsal navicular bone. In this condition, the tarsal navicular bone breaks into fragments before healing and hardening. Signs and symptoms are usually mild and may include limping, swelling and pain in the affected foot.  The condition most often affects children aged 3 to 5 years and usually involves just one foot. Although the underlying cause it not well understood, it is thought to be due to interruption of blood flow to the navicular bone, resulting in degeneration of the bone. Treatment may involve rest and avoidance of excessive weight-bearing.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
