What Causes Bunions?
What causes Bunions?
A bunion (also referred to as hallux valgus) is often described as a bump on the side of the big toe. But a bunion is more than that. The visible bump actually reflects changes in the bony framework of the front part of the foot. The big toe leans toward the second toe, rather than pointing straight ahead. This throws the bones out of alignment—producing the bunion’s bump.
Bunions are a progressive disorder. They begin with a leaning of the big toe, gradually changing the angle of the bones over the years and slowly producing the characteristic bump, which becomes increasingly prominent. Symptoms usually appear at later stages, although some people never have symptoms.
Bunions are most often caused by an inherited faulty mechanical structure of the foot. It is not the bunion itself that is inherited but certain foot types that make a person prone to developing a bunion. Although wearing shoes that crowd the toes will not actually cause bunions, it sometimes makes the deformity get progressively worse. Symptoms may therefore appear sooner.
Symptoms of a Bunion
Symptoms, which occur at the site of the bunion, may include:
- Pain or soreness
- Inflammation and redness
- A burning sensation
- Possible numbness
Symptoms occur most often when wearing shoes that crowd the toes, such as shoes with a tight toe box or high heels. This may explain why women are more likely to have symptoms than men. In addition, spending long periods of time on your feet can aggravate the symptoms of bunions.
Treatment for a Bunion
Sometimes observation of the bunion is all that is needed. To reduce the chance of damage to the joint, periodic evaluation and x-rays by your surgeon are advised.
In many other cases, however, some type of treatment is needed. Early treatments are aimed at easing the pain of bunions, but they will not reverse the deformity itself.
- Changes in footwear. Wearing the right kind of shoes is very important. Choose
shoes that have a wide toe box and forgo those with pointed toes or high heels,
which may aggravate the condition.
- Padding. Pads placed over the area of the bunion can help minimize pain. These can
be obtained from your surgeon or purchased at a drug store.
- Activity modifications. Avoid activity that causes bunion pain, including standing for long periods of time.
- Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation.
- Icing. Applying an ice pack several times a day helps reduce inflammation and pain.
- Injection therapy. Although rarely used in bunion treatment, injections of
corticosteroids may be useful in treating the inflamed bursa (fluid-filled sac located
around a joint) sometimes seen with bunions.
- Orthotic devices. In some cases, custom orthotic devices may be provided by the
