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
Improper footwear. Podiatric physicians have long believed that narrow, poor-fitting shoes with a tight toe box tend to compress the end of the foot, leading to abnormal motion of the foot and pressure over the MTP joint. High-heeled shoes tend to add even more pressure to the toes, as the foot slides downward. Over time, continued pressure will squeeze the toes together, encouraging the deformity. Occupational hazards. Individuals whose jobs place undue stress on their feet are among those who complain of bunions. Ballet dancers, in particular, put great demands on their toes, and thus are often subject to bunions, however, they are not alone. Many professionals whose jobs require a great deal of standing or walking (teachers, police officers, doctors and nurses, etc.) and/or who are required to wear a particular type of shoe or boot as part of a uniform, also are at risk. Athletes such as runners or walkers, who utilize the wrong footwear, may also develop bunions.
Symptoms
Bunions may or may not cause symptoms. A frequent symptom is foot pain in the involved area when walking or wearing shoes; rest relieves this pain. A bunion causes enlargement of the base of the big toe and is usually associated with positioning of the big toe toward the smaller toes. Shoe pressure in this area can cause interment pain while the development of arthritis in more severe bunions can lead to chronic pain. Bunions that cause marked pain are often associated with swelling of the soft tissues, redness, and local tenderness. It is important to note that, in postpubertal men and postmenopausal women, pain at the base of the big toe can be caused by gout and gouty arthritis that is similar to the pain caused by bunions.
Diagnosis
People with bunions may be concerned about the changing appearance of their feet, but it is usually the pain caused by the condition that leads them to consult their doctor. The doctor will evaluate any symptoms experienced and examine the affected foot for joint enlargement, tissue swelling and/or tenderness. They will also assess any risk factors for the condition and will ask about family history. An x-ray of the foot is usually recommended so that the alignment of big toe joint can be assessed. This would also allow any other conditions that may be affecting the joint, such as arthritis, to be seen.
Non Surgical Treatment
Padding with a number of different materials (eg felt) to reduce pressure on the painful prominence of the bunion. Physical therapy can be used to help with the symptoms and improve the range of motion (this is particularly helpful if the pain is coming from inside the joint, rather than from shoe pressure). Manipulation of the joint can be used to help with this (manipulation will never correct the alignment of the joint). Any corns and calluses that are causing symptoms should be treated. The correct fitting of footwear is essential for anyone who is serious about doing something about their bunions and hallux valgus. It may be possible to have your shoes stretched over the area of the bunion to also relieve pressure. Foot orthotics may be useful in helping with the instability about the joint. They may be more helpful if there are other symptoms in the foot as well, as their use in "treating" bunions is controversial. They may play a role in slowing progression and in the prevention of bunions developing again after surgical correction. Exercises can be important in maintaining the mobility of the joint in those with bunions, this is especially important for the arthritic type pains that may be originating from inside the joint and for the prevention of these painful symptoms in the future.
Surgical Treatment
There are dozens and dozens of types of surgery designed to address bunion deformities, and each have different indications. But in short, some procedures simply address an enlarged bump. Some simply address a crooked big toe. But in order to slow the return of the bunion deformity, most procedures aim to realign the big toe with the bone behind it, the "first metatarsal." This would also realign the joint surfaces between those two bones. But even if the surgery is designed to realign the big toe, there are still many choices to consider. Some procedures are meant for a short first metatarsal and others for a long first metatarsal. Some are best when the foot is very unstable, others are based on the severity of the arthritis present. In fact, there are many, many factors to consider when designing a procedure to address a particular patient's foot, to the extent that what's involved in a bunion surgery not only varies from patient to patient--the procedures often vary even from a patient's right foot to the left foot.
