A bunion occurs when the bones at the base of the big toe move out of alignment. The big toe may lean toward or move underneath the second toe. The second toe may move out of alignment and overlap the third toe. Long term irritation causes the base of the big toe to enlarge and a fluid-filled sac may form. This creates a large bump on the side of the foot at the joint.
SymptomsA bunion causes the base of your big toe to stick out and form a bump on the side of your foot. A bunion can be large, red, swollen, and painful. The skin on the bottom of your foot may thicken and form a painful callus. It may hurt to bend your toe, walk, or wear shoes.
A bunion causes your foot to look different. Your big toe may lean towards your second toe. The first few toes on your foot may lean and overlap.
TreatmentSimply changing shoes may treat some bunions. It is helpful to wear wide-toed shoes with low heels. Good foot care and felt or foam pads worn between the toes or on the foot may help protect the area and prevent further discomfort. Custom-made shoe inserts can help position the toe and relieve pain.
SurgeryIf non-surgical treatments fail, surgery may be necessary to restore normal alignment, pain-free movement and function. Bunion surgery is used to realign the bones, joints, tendons, ligaments, and nerves. The toes are placed in their correct positions and the bony bump is removed. There are numerous surgical techniques for treating bunions. Your doctor will discuss the most appropriate options for you.
Bunion surgery is an outpatient surgical procedure. An ankle-block anesthesia or general anesthesia may be used so that you do not feel pain during the procedure. Following the surgery, the bones are held in position with wires, screws plates, or cast while they heal.
