What is a Bunion?
A bunion is described as a bump on the side of the big toe. The bump actually reflects a change in the bony framework of the front part of the foot. The big toe leans toward the second toe, rather than pointing straight. This throws the bones out of alignment, creating the bunion’s bump. Bunions are a progressive disorder and will usually get worse over time.
What causes a Bunion?
Bunions are most often caused by an inherited faulty mechanical structure of the foot. It is not the bunion itself that is inherited but certain foot types that make a person prone to developing a bunion. Wearing shoes with a narrow toe box will sometimes make the deformity get progressive worse
What are symptoms of a Bunion?
Symptoms at the site of the bunion include pain or soreness, inflammation and redness, skin irritation, a burning sensation at the bunion site and possible numbness,
What are surgical treatments for a Bunion?
The surgical techniques below may be a choice to correct a bunion deformity.
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, a surgical shoe or boot is worn for a few weeks.
Base Osteotomy:
With this procedure, a wedge of bone is removed from the first metatarsal bone, farther back than in the head chevron osteotomy. The bony bump is also removed. To heal correctly, your foot may be placed in the cast or cast boot. You may be asked not to bear weight on the surgery foot for a few weeks.
Fusion or removal of part of the joint:
This is typically done if there is arthritis that has damaged the joint itself.
