Overview
A bunion or hallux valgus is a prominence on the inner border of the foot effecting the big toe and at the level of the 1st metatarso-phalangeal (MTP) joint. The bunion prominence which is seen and felt on the inner border of the foot is not due to any growth of bone but is due to the 1st metatarsal bone. With a bunion this has become more prominent than normal because the 1st metatarsal has moved away from its immediate neighbour the 2nd metatarsal. This widens the forefoot thus producing the bunion. An inevitability of the splaying of the foot which occurs with a bunion or hallux valgus is that the great toe itself is then pulled across in the opposite direction (towards the second toe) by the still normally located tendons of the big toe. A bunion or hallux valgus is commonly confused with hallux interphalangeus (where the deformity lies more distally and which tends to be less problematic). Here there is no increase in the space between the metatarsals, and the deformity lies in the shape of the phalynx bone.
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.
Symptoms
Audible clicking (called ?crepitus?) and/or stiffness in the affected joint which indicates that the joint surfaces are rubbing together improperly. Inflammation, degeneration of the surfaces of the joint, deformity (including bone growth at the joint line and displacement of the toe) and ultimately, loss of range of motion in the joint. Pain at the side and top of the joint that worsens with walking and physical activity.
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
The most common cause of a bunion is over pronation, this is when your foot rotates in too much as you walk. You really need to treat the underlying cause of the bunion as soon as possible to prevent any further damage. Wear wide fitting shoes, preferably with a leather upper which will allow a stretch. Avoid high heeled shoes. Bunion exercises will help to keep the joint flexible. Bunion surgery may be required in some patients, however this should only be considered when all non-surgical treatment options have been used. Bunion surgery has improved dramatically over the last 20 years but it still cannot guarantee a total recovery and often post operative complications such as calluses and corns can occur depending on the procedure used. If your bunion becomes painful, red and swollen, try using ice on the joint and elevate the foot on a stool. Bunion Night Splints can reduce the size of the bunion. This will straighten the bunion while you sleep. A Bunion Shield can reduce the pain over the bunion. Performing stretches on your toes and feet while you go about your daily routine. This increases circulation, red blood cell activity, and bone realignment. The easiest way to do this is by using a soft, flexible, medical grade gel Toe stretcher which is gentle between the toes and helps to straighten your toes.
Surgical Treatment
Bunion surgery is most often done on an outpatient or day-surgery basis, usually with a local anesthetic technique called an ankle block. The surgery typically takes an hour or two to perform. Following your surgery, you will stay in the Recovery Room for several hours while the anesthetic wears off. For your safety, you will be required to have someone to drive you home. You should keep in mind that any surgery carries with it very small-but-possible risks of complications such as allergic reaction to anesthesia, bleeding and infection.
