Overview

Bunions are probably the most common foot disorder seen in podiatry. The term bunion itself is used by patients describing the bony lump found near the base of the big toe, which is usually an adaptation of the positional change of the big toe. Hallux abducto valgus (HAV) is a medical term, which describes the position of the hallux (big toe) with respect to the connecting bone of the mid foot (metatarsal). In this foot disorder, the hallux deviates towards the lesser toes and the metatarsal moves towards the midline.

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.
SymptomsIf you have a bunion, you may have pain or stiffness of your big toe joint, swelling of your big toe joint, difficulty walking, difficulty finding shoes that fit. These symptoms may be caused by conditions other than bunions, but if you have any of these symptoms, see your doctor.

Diagnosis
Although bunions are usually obvious from the pain and unusual shape of the toe, further investigation is often advisable. Your doctor will usually send you for X-rays to determine the extent of the deformity. Blood tests may be advised to see if some type of arthritis could be causing the pain. Based on this evaluation, your doctor can determine whether you need orthopaedic shoes, medication, surgery or other treatment.

Non Surgical Treatment
One of the best things you can do is to go for wider, deeper shoes. Trevor Prior says there should be a centimeter between the end of your longest toe and end of shoe. You should also choose shoes with an adjustable strap or lace. Podiatrists often recommend exercises to strengthen muscles and tendons around the big toe. Here?s one you can try yourself. Put your feet side by side, and try to move your big toes towards each other. Do this three or four times a day, while you?re in the bath or in bed.


Surgical Treatment
One of the more popular proximal metatarsal osteotomies that is performed is called the Myerson/Ludloff procedure. This operation is performed for more advanced deformity. Screws are inserted into the metatarsal to hold the bone cut secure and speed up bone healing. Walking is permitted in a surgical shoe following surgery. The shoe is worn approximately 5 weeks.

Prevention
Shop for shoes that possess a removable liner, or insole, and stand on the liner after you have removed it from your shoe. This is an effective method to see if your shoe is wide enough in the forefoot to accommodate your bunion. If your bunion and forefoot are wider than the insole, your shoe will squeeze and constrict your bunion and create the symptoms that define this health problem. The insole should also be wide enough to fully accommodate your big toe when it points outward, away from your other toes.
