Overview
A bunion is a foot deformity where your big toe slants outward horizontally, pushing the tip of the big toe up against your little toes, and creating a characteristic sharp angle along the inside of your foot, at what?s called the first metatarsophalangeal joint-where your big toe connects to your foot. The reason for the deformity is an abnormal growth of bone, so it is not a condition that will correct itself naturally. Though bunions, or hallux valgus, as they are known in the medical community, are well-known among the general population for causing pain and discomfort, they can have a big impact on your running as well. Women?s marathon world record holder Paula Radcliffe, for example, lost several months of running because of a bunion on her foot.
Causes
Bunions are the byproduct of unnatural forces and motion being applied to the joints and tendons of your foot over a prolonged period of time. They can also be caused by traumas to the foot as well as congenital deformities. Occupations or athletic activities that place abnormal stress on your feet can also lead to the formation of bunions. Bunions have a tendency to run in families, but it?s not the bunion itself that is hereditary. It?s the the foot type which *causes* the bunion that is hereditary. Also, wearing shoes such as high heels that do not distribute your body weight evenly can lead to bunions, which explains why so many women suffer from bunions.
Symptoms
Bunions may cause no pain at first. But as the big toe begins to turn in towards the other toes, people with bunions usually experience redness, pain, swelling, and tenderness in the area around the joint. Pressure inside the joint or from footwear pressing against the bunion may also cause discomfort. As the affected toe curves closer to the other toes on the foot, these toes can become painful as well. Complications of bunions include corns, calluses, hammer toe, and ingrown toenails. Other complications include irritation of the nerves surrounding the bunion area. Excess rubbing of the bunion against the footwear may lead to changes in the skin, resulting in corns or calluses. Hammer toe is a deformity of the toe immediately next to the big toe. A hammer toe is slightly raised and points upwards from the base and downwards at the end of the toe. Ingrown toenails can result from increased pressure from the big toe on the other toes. There may also be a decrease in the amount a person can move the joint affected by the bunion. Irritation of the nerves will feel like burning or decreased sensation.
Diagnosis
Bunions are readily apparent - the prominence is visible at the base of the big toe or side of the foot. However, to fully evaluate the condition, the foot and ankle surgeon may take x-rays to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don?t go away, and will usually get worse over time. But not all cases are alike - some bunions progress more rapidly than others. Once your surgeon has evaluated your bunion, a treatment plan can be developed that is suited to your needs.
Non Surgical Treatment
Your podiatrist can recommend exercises, orthoses (special devices inserted into shoes), shoe alterations or night splints (which hold toes straight over night) which may slow the progression of bunions in children. According to experts, ?conservative? measures such as these may help relieve symptoms, though there is no evidence they can correct the underlying deformity. Orthoses are designed to prevent the problem getting worse by decreasing any biomechanical causes of bunions. In other words, if the biomechanical theory is correct (i.e. if your bunions are caused by the way you walk), orthoses may help you walk in a way that doesn?t exacerbate the problem. But it won?t change the already established shape of your foot. For that, you need surgery.
Surgical Treatment
In severe hallux valgus bunion cases, the first long bone (metatarsal) in the foot dramatically shifts away from the second metatarsal, resulting in looseness and a large deformity. In severe bunion corrections, a surgery known as the Lapidus procedure realigns the first metatarsal into its natural position. Using screws, the surgery holds the bone stable so it does not shift again and reduces the change of the bunion returning to basically none. Surgery may also involve removing the enlarged portion of the bunion region, cutting and realigning the bone, and correcting the position of the tendons and ligaments. By using a special plate with Lapidus procedures, University Foot and Ankle Institute patients are able to put weight on their foot after only 2-3 weeks, rather than the typical 6-8 weeks of no weight.
