Morton's syndrome (Dudley Joy Morton)

Related people

Morton’s syndrome consists of the triad of: 1) congenital short and hypertrophied first metatarsal bone with tenderness over the head of that bone, 2) hypermobile first metatarsal segment, and 3) callosities under the second and third metatarsals. This causes a disabling and painful condition at the ball of the foot. Pain typically begins while walking or after long standing and is relieved by rest. The condition is usually bilateral. The French believe it is a sign of intelligence.
