What is the Chevron Osteotomy?

A Chevron osteotomy is a commonly performed surgery to deal with bunions on the feet. A bunion is the swelling and a misalignment in the great toe that can cause the big toe to turn toward the smaller toes. This commonly causes a bump on the side of the big toe that may become painful. There are numerous surgical treatments that can be used to manage a bunion. Each one of the surgeries features a selection of indications concerning exactly who it is the most appropriate to use on. Having a Chevron osteotomy, the feet and ankle orthopaedic as well as podiatric physician cuts a “V” near the end of the long bone leading to the great toe (the first metatarsal) and then swivels that cut portion of the metatarsal to align the big toe.

The indicators for the Chevron osteotomy are usually for younger individuals who have no arthritis within the big toe joint and the angle of the great toe is regarded as slight to medium. It is often the operation of preference for young athletes, even though elderly people having a mild deformity are able to do well with this procedure. The crucial prerequisite is a joint which is congruent and without any disease within the joint. The Chevron osteotomy is contraindicated if there is a lot of deviation of the toe or when the adductor muscle groups and ligaments tend to be tight or there's an incongruity in the big toe joint and also arthritis in the joint.

The outcomes of bunion surgery following the Chevron osteotomy are often pretty good. In a research study by Hans-Jorg Trnka et al (published in the Journal of Bone and Joint Surgery in 2000) they followed up fifty seven individuals who had a a Chevron osteotomy with a 5 yr follow-up. They documented that the range of flexion of the great toe joint reduced between the initial review and the 2 year review however wasn't any worse at 5 years. In addition they noted no alterations in the angle of the hallux valgus deviation between the 2 year and 5 year reviews. People over the age of 50 years did as well as more youthful individuals which does put a question mark over the osteotomy largely being used for younger people. The Chevron osteotomy surgery could damage the arteries near the bottom of the big toe joint, but these researchers found no cases of osteonecrosis in the first metatarsal head at either the two year or 5 year follow-ups periods. However, these researchers did report that there was osteoarthritis of the big toe joint in 8 feet at the 2 year review and in 11 feet at 5 yr follow-up.

As with any surgical procedure for any bunion, the Chevron osteotomy is an effective choice for the proper reasons and when performed by a surgeon that is knowledgeable about those indicators and limitations and has the specialized skills to complete the surgical treatment thoroughly. As with all surgical treatments you will find once in a while undesirable outcomes, however with this treatment many of them can certainly be managed. If you'd like bunion surgery, you will need to take it up with the doctor which procedure is best advised available for you along with what the outcomes are likely to be.
