Overview

A bunion is an abnormal, bony bump that forms on the joint at the base of your big toe. Your big toe joint becomes enlarged, forcing the toe to crowd against your other toes. This puts pressure on your big toe joint, pushing it outward beyond the normal profile of your foot, and resulting in pain. Bunions can also occur on the joint of your little toe (bunionette). Bunions can occur for a number of reasons, but a common cause is wearing shoes that fit too tightly. They can also develop as a result of inherited structural defect, injury, stress on your foot or another medical condition.

Causes
The exact cause of bunions is unknown, but they tend to run in families. Wearing badly fitting shoes is thought to make bunions worse. It's also thought that bunions are more likely to occur in people with unusually flexible joints, which is why bunions sometimes occur in children. In some cases, certain health conditions, such as rheumatoid arthritis and gout, may also be responsible.
SymptomsSymptoms include pain in and around the ball of the big toe, usually from the bone rubbing too much against the shoe. You may be unable to wear certain types of shoes due to the shape of the forefoot. The big toe appears to be bent inwards towards and in come cases over the inside toe.

Diagnosis
Physical examination typically reveals a prominence on the inside (medial) aspect of the forefoot. This represents the bony prominence associated with the great toe joint ( the medial aspect of the first metatarsal head). The great toe is deviated to the outside (laterally) and often rotated slightly. This produces uncovering of the joint at the base of the big toe (first metatarsophalangeal joint subluxation). In mild and moderate bunions, this joint may be repositioned back to a neutral position (reduced) on physical examination. With increased deformity or arthritic changes in the first MTP joint, this joint cannot be fully reduced. Patients may also have a callus at the base of their second toe under their second metatarsal head in the sole of the forefoot. Bunions are often associated with a long second toe.

Non Surgical Treatment
Bunion pain can be successfully managed in the vast majority of cases by switching to shoes that fit properly and don't compress the toes. Your orthopaedic surgeon can give you more information about proper shoe fit and the types of shoes that would be best for you. Follow these general points of shoe fit. Do not select shoes by the size marked inside the shoe. Sizes vary among shoe brands and styles. Judge the shoe by how it fits on your foot. Select a shoe that conforms as nearly as possible to the shape of your foot. Have your feet measured regularly. The size of your feet change as you grow older. Have both feet measured. Most people have one foot larger than the other. Fit to the largest foot. Fit at the end of the day when your feet are the largest. Stand during the fitting process and check that there is adequate space (3/8" to 1/2") for your longest toe at the end of each shoe. Make sure the ball of your foot fits well into the widest part (ball pocket) of the shoe. Do not purchase shoes that feel too tight, expecting them to "stretch" to fit. Your heel should fit comfortably in the shoe with a minimum amount of slippage. Walk in the shoe to make sure it fits and feels right. (Fashionable shoes can be comfortable.) Some shoes can be modified by stretching the areas that put pressure on your toes. Splints to reposition the big toe and orthotics (special shoe inserts shaped to your feet) also may relieve pain. For bunions caused by arthritis, medications can be prescribed to reduce pain and swelling.


Surgical Treatment
When the pain of a bunion interferes with daily activities, and conservative treatment has been completed it's time to discuss surgical options. Foot Mechanics has excellent relationships with many Orthopaedic Surgeons, who are the specialists who perform bunion surgery. Because bunions are caused by faulty foot mechanics surgery can improve the look of your feet by removing the ?bump? but if the underlying mechanics are not addressed then the bunion is likely to return. For this reason orthotics are used post-surgery to prevent the return of bunions.
