A bunionette deformity is an abnormal bony prominence, or bump, on the outer side at the base of the fifth toe (the "pinky toe") at the metatarsophalangeal joint (MTPJ). The bony prominence can start out small and painless but become larger and more painful over time.
A bunionette (also known as a tailor's bunion) is a painful bony prominence, or bump, on the outside of the fifth (little) toe. Over time, the bunionette may worsen as the fifth toe moves inward and the fifth metatarsal (the bone connected to it) moves outward.
This surgery is used to treat flexible hammertoe deformity. A hammertoe deformity is one in which the toe is bent and looks like a hammer. A flexible deformity is one in which the toe can be manipulated into a straight position.
A hammertoe is a deformity that causes a toe to become bent upward in the middle so it resembles a hammer. This can cause the toe to rub against the top of the shoe or irritate the end of the toe by jamming it into the ground. Hammertoes often occur in conjunction with other toe problems.
