What is the Chevron Osteotomy?

The Chevron osteotomy is a commonly performed surgery to deal with bunions on the foot. A bunion is the swelling and a misalignment with the great toe or hallux which causes the big toe to turn towards the smaller toes. It usually results in a lump on the side of the big toe joint which can turn out to be sore. There are several surgical treatments which you can use to deal with a bunion. Each one of the surgeries carries a variety of indications as to exactly who it will be most suitable to use on. By using a Chevron osteotomy, the foot and ankle orthopaedic as well as podiatric surgeon cuts a “V” at the end of the long bone leading to the big toe (the metatarsal) and then turns the end of the bone to push back the great toe.

The actual indicators for a Chevron osteotomy are in general for younger people who have no arthritis within the great toe joint and the amount of the deformity is considered mild to medium. It is usually the surgery usually chosen for young athletes, although elderly people having a moderate deformity will do well with this procedure. The significant necessity is a great toe joint which is congruent and with no osteoarthritis in the great toe joint. The Chevron osteotomy can be contraindicated when there is a significant amount of deviation of the toe or if the adductor muscle groups as well as ligaments tend to be tight or there's an incongruity in the big toe joint and also osteoarthritis in the joint.

The outcome of bunion surgical treatment after the Chevron osteotomy are in general pretty good. In a study by Hans-Jorg Trnka and co-workers (in the JBJS in 2000) where they followed up 57 people who underwent the Chevron osteotomy with five yr follow-up. They recorded that the range of flexion of the great toe joint decreased between the initial evaluation and the two year review however was no worse at 5 years. In addition they documented no alterations in the angle of the hallux valgus deformity relating to the 2 year and five year assessments. Individuals over the age of fifty years did as well as younger individuals that places a question mark over the osteotomy largely being used for younger individuals. The Chevron osteotomy operation might harm the arteries nearby the base of the great toe or hallux, but these researchers uncovered no cases of osteonecrosis of the first metatarsal bone at both the 2 year or 5 year follow-ups time frames. Nevertheless, they did report that there was osteoarthritis of the big toe or hallux joint in eight feet at the two year review and in 11 feet at 5 yr follow-up.

Just like any surgical treatment for any bunion, the Chevron osteotomy is a great alternative for the correct indicators and when performed by a surgeon who is experienced with those reasons as well as contraindications and also has the technical abilities to execute the surgical treatment meticulously. Just like any surgical procedures you can find occasionally undesirable outcomes, although with this procedure most of them are generally managed. If you need bunion surgery, you will need to take it up with the surgeon which procedure is better suggested to suit your needs and what the final results are most likely to be.
