Claw toe is a deformity where a toe bends and appears like a bird’s claw. The affected toe is bent upward from the joint at the ball of the foot, and downward at the joints in the middle and tip of the toe to curl under the foot. Hard, thick skin called corns may develop under the ball of the foot or on the top of the affected toe, causing pain while walking.
A hammertoe is a deformity of a lesser toe (second through fifth toes), where the toe is bent upward at the toe’s middle joint, resembling a hammer. The bent portion may rub against a shoe causing pain, irritation and development of corns.
A bunion is a bony protuberance that appears on the outer surface of the big toe when it angles toward the adjacent toe. It is an extra bone and a fluid-filled sac that grows at the base of the big toe.
