Patients with a shorter toe than their other toes have a clinical disorder named brachymetatarsia which is due to the shortening of one of the metatarsals.
This problem is usually present at birth although in some cases it can be due to the consequence of growth detention during infancy. This causes the toe of the affected metatarsal to grow to a lesser degree with neighbouring toes occupying its space resulting in the appearance of deformed toes mounted one on top of the other.
Surgical treatment for this serious problem is done by lengthening the affected metatarsal by means of implanting a device which lengthens the bone to the desired length. Once the correct bone length is achieved, adequate toe length is also acquired, re-establishing a good cosmetic appearance and even foot functionality improvement.
