Overview
A bunion (hallux valgus) is an enlargement of the bone or tissue around a joint at the base of the big toe or at the base of the little toe (in which case it is called a "bunionette" or "tailor's bunion"). Bunions often occur when the joint is stressed over a prolonged period. Ninety percent of bunions occur in women, primarily because women may be more likely to wear tight, pointed, and confining shoes. Bunions may be inherited as a family trait. Bunions may also result from arthritis, which often affects the big toe joint.
Causes
While the precise cause is not known, there seem to be inherited (genetic) factors that lead to abnormal foot function like overpronation that can predispose to the development of bunions. This is especially common when bunions occur in younger individuals. This abnormal biomechanics can lead to instability of the metatarsal phalangeal joint and muscle imbalance resulting in the deformity. Although shoe gear doesn't directly cause a bunion, it can certainly make the bunion painful and swollen. Other less common causes of bunion deformities include trauma (sprains, fractures, and nerve injuries), neuromuscular disorders (polio or Charcot-Marie-Tooth disease) and limb-length discrepancies (one leg shorter than the other) where the longer leg develops the bunion.
Symptoms
Signs and symptoms of a bunion include the base of the big toe is swollen and sticks out. The big toe is often bent towards the other toes, and sometimes the second toe is pushed to overlap the third toe. Skin around the big toe joint is red and sore. Thickened skin at the base of the big toe. Pain in the big toe or foot. Wearing shoes is painful. Pain or difficulty when walking.
Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.
Non Surgical Treatment
Bunions can be treated conservatively (without surgery) using simple measures such as well-fitting shoes, orthoses simple painkillers and padding. Physiotherapy can help improve associated muscle imbalances. Such measures will not correct or even stop the deformity but they can help with symptoms. When non-surgical treatments prove insufficient, surgery can relieve your pain, correct any related foot deformity and help you resume your normal activities.
Surgical Treatment
Surgery for bunions usually isn't done unless you have already tried other treatment and it did not relieve your pain. Other treatment includes wearing shoes with lots of room for your toes and using pads and supports in your shoe for protection and comfort. Surgery may be right for you if your toe is too painful, if your bunion is very big, or if you can't easily do your daily activities. It's not clear how well bunion surgery works or which kind of surgery is best. How well the surgery works depends on how bad your bunion is, the type of surgery you have, and your surgeon's experience. Your expectations will play a big role in how you feel about the results of surgery. If you want surgery mainly to improve the way your foot looks, you may be disappointed.
