Does the Chevron osteotomy help bunions?

The Chevron osteotomy is a commonly performed surgery to treat bunions on the foot. A bunion is an enlargement and a misalignment of the great toe or hallux that can cause the big toe to angle in the direction of the smaller toes. It typically results in a bump on the side of the big toe joint that can grow to be sore. There are many surgical procedures which can be used to take care of a bunion. Each of the surgeries features a number of indications concerning exactly who it's most suitable to use on. Having a Chevron osteotomy, the foot and ankle orthopaedic or podiatric surgeon cuts a “V” at the end of the long bone leading to the big toe (the metatarsal) and then moves that cut portion of the bone to straighten the big toe.

The particular indicators for a Chevron osteotomy are typically for younger individuals who have no osteoarthritis within the big toe joint and the amount of the bunion is considered mild to medium. It is usually the surgery of choice for younger sports athletes, although older people with mild deformity will do well with this operation. The significant prerequisite is a hallux joint that is congruent and with no osteoarthritis in the joint. This Chevron osteotomy is contraindicated if there is a great deal of deformity or when the adductor muscles as well as ligaments will be restricted or there's an incongruity in the big toe joint and also osteoarthritis present.

The outcome of bunion surgical treatment following the Chevron osteotomy usually are pretty good. In a research study by Hans-Jorg Trnka and others (published in the JBJS in 2000) where they followed up fifty seven people who went through a Chevron osteotomy with a five yr follow up. They documented that the range of flexibility of the great toe joint decreased between the first assessment and the two year review but wasn't any worse at 5 years. They also noted no changes in the angle of the hallux valgus deviation relating to the 2 year and 5 year assessments. Individuals over the age of fifty years did as well as more youthful patients which puts a question mark over the osteotomy principally getting indicated for younger people. The Chevron osteotomy procedure could damage the blood vessels close to the bottom of the big toe joint, however these authors observed zero cases of osteonecrosis in the first metatarsal head at either the two year or 5 year follow-ups periods. Nevertheless, these researchers did find that there was osteoarthritis of the big toe joint joint in 8 feet at the 2 year review as well as in 11 feet at five yr review.

As with every surgical treatment for a bunion, the Chevron osteotomy is a great alternative for the right indications and when carried out by a surgeon who is informed about those reasons and limitations and has the technical competencies to complete the surgery diligently. Just like any surgeries there are actually once in a while negative outcomes, however with this procedure the majority of them can certainly be not hard to fix. If you would like bunion surgery, you will need to take it up with the surgeon which treament is best advised in your case and what the final results are likely to be.
