Morton's toe
Type of brachymetatarsia affecting the big toe
Morton's toe
Morton's toe, also known as Greek toe, is the condition of having a first metatarsal bone that is shorter than the second metatarsal (see diagram). It is a type of brachymetatarsia. This condition is the result of a premature closing of the first metatarsal's growth plate, resulting in a short big toe, giving the second toe the appearance of being long compared to the first toe. The metatarsal bones behind the toes are of different lengths, and the relative lengths vary between people. For most feet, a smooth curve can be traced through the joints at the bases of the toes (the metatarsal-phalangeal, or MTP, joints), but in Morton's foot, the line must bend more sharply to go through the base of the big toe, as shown in the diagram. This is because the first metatarsal, behind the big toe, is short compared to the second metatarsal, next to it. The longer second metatarsal puts the MTP joint at the base of the second toe further forward. If the big toe and the second toe are the same length...
