Bunion is a prominence of the medial portion of the head of the 1st metatarsal bone. The cause is often variations in position of the 1st metatarsal bone or great toe, such as lateral angulation of the great toe (hallux valgus). Secondary osteoarthritis and spur formation are common. Symptoms may include pain and redness, bursitis medial to the joint, and mild synovitis. Diagnosis is usually clinical. Treatment is usually a shoe with a wide toe box, protective pads, and orthotics. For bursitis or synovitis, corticosteroid injection may be helpful. Causes
Some people develop bunions from wearing shoes that do not fit correctly (especially high heels or narrow-toed shoes). For other people, bunions are caused by factors beyond their control. These can include a family history of a foot type that is susceptible to bunions, neuromuscular disorders, conditions affecting the joints (e.g., arthritis), severe injury to the foot, deformities at birth, problems that affect the way a person walks (e.g., rolling in at the ankles).
Symptoms
Just because you have a bunion does not mean you will necessarily have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint, swelling on the inside of your foot at the big toe joint, appearance of a "bump" on the inside edge of your foot. The big toe rolling over to one side. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes - especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include Corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint.
Diagnosis
A doctor can very often diagnose a bunion by looking at it. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen.
Non Surgical Treatment
The treatment of bunions should be individualized because the degree of deformity is not always consistent with the degree of pain. The most important first step in the treatment (and prevention) of bunions is to wear properly fitted shoes, with a low heel and adequate room in the toe area. Further treatment may include relative rest and icing to decrease pain around the MTP joint, medications to reduce inflammation and pain, stretching and strengthening exercises and shoe orthotics. If the above measures are not successful, surgery may be required.
Surgical Treatment
Bunion surgery is an option for those who have persisting pain and the condition is worsening. Surgery on a bunion can correct the bone deformity, increase function and relieve pain. Bunion surgery should not be considered lightly, the surgery is often successful but there is a rate of surgical failure. The big toe can move back into its previous place if the patient does not follow instructions, which will result in the pain returning. The surgical failure for bunions can be reduced greatly if activity restrictions are followed and proper footwear is worn after surgery.
Prevention
The best way to reduce your chances of developing bunions is to wear shoes that fit properly. Shoes that are too tight or have high heels can force your toes together. Bunions are rare in populations that don?t wear shoes. Make sure your shoes are the correct size and that there's enough room to move your toes freely. It's best to avoid wearing shoes with high heels or pointed toes.
