The Chevron osteotomy is a frequently performed surgical procedure to treat bunions on the foot. A bunion is the enlargement and a misalignment of the big toe or hallux that causes the big toe to turn towards the lesser toes. This usually results in a bump at the base of the big toe that may turn out to be sore. There are many different surgical treatments that can be used to treat a bunion. Each of the surgeries features a selection of indications as to who it's the best option for. Using a Chevron osteotomy, the feet and ankle orthopaedic or podiatric physician cuts a “V” at the end of the long bone leading to the great toe (the first metatarsal) and then swivels the end of the bone to correct the big toe.
Typically the indications for a Chevron osteotomy are in general for younger people who have no arthritis in the joint and the amount of the big toe is considered mild to moderate. It is often the surgery of choice for young athletes, although older people with moderate bunion will do well with this operation. The vital necessity is a hallux joint which is congruent and without any arthritis in the hallux joint. A Chevron osteotomy will be contraindicated if you have a great deal of deformity or if the adductor muscle groups as well as ligaments will be restricted or there's an incongruity in the big toe joint and also osteoarthritis in the joint.
The end results of bunion surgical treatment using the Chevron osteotomy usually are pretty good. In a study by Hans-Jorg Trnka and others (published in the Journal of Bone and Joint Surgery in 2000) they studied 57 people who underwent a Chevron osteotomy with five year follow-up. They reported that the range of flexion of the great toe joint decreased between the initial assessment and the two year review however was no worse at five years. They also noted no changes in the angle of the hallux valgus deviation between the 2 year and 5 year evaluations. Individuals over the age of fifty years did as well as more youthful patients which does put a question mark over the osteotomy generally being indicated for younger people. The Chevron osteotomy procedure could harm the blood vessels close to the bottom of the big toe or hallux, but these investigators observed zero cases of osteonecrosis of the first metatarsal bone at either the two year or five year follow-ups periods. Nevertheless, these authors did state that there was osteoarthritis of the great toe or hallux joint in eight feet at the two year follow-up as well as in eleven feet at five yr follow-up.
As with any operation for any bunion, the Chevron osteotomy is a great choice for the proper indicators and when carried out by a surgeon that is informed about those indications as well as limitations and possesses the specialized expertise to carry out the procedure diligently. As with every surgical procedures there are actually sometimes negative outcomes, although with this procedure many of them are easily not hard to fix. When you need bunion surgery, you will need to take it up with the surgeon which treament is best advised for you along with what the outcomes are most likely to be.
