Hallux valgus/ bunion
A bunion is one problem that can develop due to hallux valgus, a foot deformity. The term “hallux valgus” is Latin and means a turning outward (valgus) of the big toe (hallux). The bone which joins the big toe, the first metatarsal, becomes prominent on the inner border of the foot. This bump is the bunion and is made up of bone and soft tissue.
Bunions rarely occur in individuals who do not wear shoes. Once a bunion is present, the deformity of hallux valgus may worsen over time.
The treatment of a bunion depends on level of pain. Since the pain from a bunion is always aggravated by shoe wear, the symptoms will often depend on the type and size of shoes worn. The perception of pain or discomfort however is varied.
Realistically, there are only two ways to treat a bunion; either change the size and shape of the shoe, or the size and shape of the foot. Due to the styles of shoes, it is obviously much easier to change the size and shape of the shoe in the male than the female.
Once a bunion gets to be irritating or painful, and shoe wear is uncomfortable, surgery may be recommended. There are many different surgical procedures that can be performed. The decision to perform one type of surgery or another is based upon the extent and magnitude of the bunion deformity, the presence of arthritis in the big toe joint, and the space between the first and second metatarsals, which is called the intermetatarsal angle.
General Facts about Chevron Bunionectomy
This operation is designed to correct the bunion and the poor alignment of the 1st metatarsal. In order to correct the 1st metatarsal, a bone cut (an osteotomy) is made, and the bone is shifted and held in place with one screw. The screw typically stays in permanently, but it can be removed if it causes any problems.
Following surgery, you will be able to wear shoes more comfortably. Care must still be taken to not wear excessively tight shoes, as we recommend for all people, regardless of whether they have a bunion or not. It will take about 6 weeks for the bone to heal, and swelling will be noted for approximately six months, although it is much less noticeable after the first month.
