The Chevron osteotomy is a commonly done surgical procedure to manage bunions on the feet. A bunion is the swelling and a misalignment in the great toe or hallux that causes the big toe to angle toward the smaller toes. It frequently produces a lump at the base of the big toe that might grow to be painful. There are numerous surgical treatments which they can use to manage a bunion. Each of the procedures has got a selection of indicators regarding exactly who it will be the best option to use on. By using a Chevron osteotomy, the foot and ankle orthopaedic or podiatric physician cuts a “V” at the end of the long bone behind the great toe (the metatarsal) after which revolves the end of the bone to straighten up the big toe.
Typically the indicators for a Chevron osteotomy are in general for younger individuals who have no osteoarthritis in the great toe joint and the amount of the great toe is considered mild to medium. It is usually the procedure of choice for younger sports athletes, even though elderly people having a moderate bunion will do well with this operation. The critical prerequisite is a big toe joint that's congruent and with no arthritis within the great toe joint. A Chevron osteotomy can be contraindicated if you have a lot of deformity or when the adductor muscles and ligaments tend to be restricted or there is an incongruity in the hallux joint and also osteoarthritis present.
The end results of bunion surgery using the Chevron osteotomy are likely to be pretty good. In a research study by Hans-Jorg Trnka and others (reported in the JBJS in 2000) they followed up fifty seven individuals who went through the Chevron osteotomy with 5 yr follow up. They reported that the range of flexibility of the great toe or hallux joint decreased between the first evaluation and the two year follow-up but wasn't any worse at 5 years. In addition, they described no alterations in the angle of the hallux valgus deformity relating to the 2 year and 5 year evaluations. People over the age of 50 years did as well as more youthful individuals which does put a question mark on the Chevron osteotomy mainly being used for younger people. The Chevron osteotomy procedure can harm the arteries nearby the base of the great toe, however these investigators found zero cases of osteonecrosis of the first metatarsal bone at either the two year or five year follow-ups time frames. However, they did report that there was osteoarthritis of the great toe or hallux joint in 8 feet at the 2 year review as well as in eleven feet at 5 yr follow-up.
Just like any operation for any bunion, the Chevron osteotomy is an excellent option for the right reasons and when performed by a surgeon that is experienced with those indicators as well as contraindications and has the technical skills to complete the procedure meticulously. As with all surgical treatments there are actually sometimes adverse outcomes, however with the Chevron osteotomy the majority of them can certainly be managed. When you need bunion surgery, you will need to take it up with the doctor which procedure is better indicated in your case and just what the final results are likely to be.
