Foot Surgery: Bunions
A bunion is a bony bump. It is most often found near the joint at the base of the big toe. Bunions often run in families. They may cause pain, swelling, and skin irritation. Wearing tight shoes doesn't cause bunions, but it can make them worse. Bunions vary from mild to severe and can be treated in many ways. Some common treatments are shown below.
Mild Bunions
When the distance between the first and second metatarsal bones is greater than normal, the big toe may turn toward the other toes. A mild bunion may then form, causing foot pain and swelling.
Head Chevron Osteotomy
The first metatarsal bone is cut. Its head is moved closer to the second metatarsal bone. A screw or pin can be used to hold the first metatarsal bone in position. The bony bump is also removed. To protect your foot, you will need to wear a surgical shoe for a few weeks.
Severe Bunions
A bunion becomes severe when the distance between the first and second metatarsal bones is greater than that of a mild bunion. The big toe turns toward the other toes, making them buckle.
Base Osteotomy
With this procedure a wedge of bone is removed from the first metatarsal bone. The bone is moved closer to the second metatarsal bone and held together with screws. The bony bump is also removed. To heal right, your foot may be placed in a cast. You may be asked not to bear weight on this foot for several weeks.
