A bunion is a bony enlargement of the big toe joint (medically called the
first metatarsophalangeal joint). A bunion forces the big toe to angle toward
the other toes. This can be a source of significant discomfort and pain. The
abnormal position of the big toe caused by a bunion is termed hallux valgus or
hallux abducto valgus (HAV).
Bunions form slowly over the years because of stress or injury to the foot.
They are frequently from wearing shoes that are too tight. Poorly fitting shoes
can alter foot motion and put pressure on the foot and toes.
Bunions can also be due to inherited foot deformities or neuromuscular
conditions such as cerebral palsy that can affect foot motion and positioning.
Arthritis may also destroy the cartilage layer in the toe joint and promote
bunion formation.
Some people are more prone to develop bunions than others. While bunions
themselves are not inherited, foot anatomy and mechanics are inherited traits
that can be passed along to children, so some families are more afflicted by
bunions than others.
Wearing high heels and poorly-fitting shoes can increase the pressure on the
toe joint and encourage development of bunions. The current footwear fashion
featuring high stiletto heels and long pointed toes are a blueprint for bunions.
Surgery is the only way to remove a bunion, but in many cases, bunions can be
managed without surgery. Pain-relieving medications, physical therapy, taping
and padding with felt or other materials, exercises, night splints, and changing
shoe types can all help control the pain associated with bunions and prevent
them from getting worse. Sometimes shoe inserts (orthotics) can help stop
progression of a bunion.
If these conservative measures do not provide relief, your doctor may
recommend surgical treatment. Bunionectomy is the term used for surgical removal
of a bunion. There are many different surgical procedures employed for bunion
relief. The thickened tissue from the big toe joint may be simply removed. Other
procedures may involve straightening the toe by removing a wedge-shaped portion
of the bone (called an osteotomy). Sometimes the bones of the toe joint may be
fused. As with any surgery, bunionectomy has its risks. Up to 10% of people
undergoing bunion surgery have complications, including infection, nerve damage,
persistent pain, or recurrence of the bunion.
