I. Definition: There
are two main types of bunions. The most
common type, known as a hallux valgus, is a painful enlargement at the base joint of the
big toe on the inside of the foot. The skin
around the joint can become swollen, red, and tender, making it painful to walk or to even
wear shoes. The big toe may begin to angle
toward the second toe, forcing both toes out of alignment.
A second type of bunion, a
hallux rigidus, is related to arthritis of the big toe.
In this condition, a bump develops on top of the base joint of the big toe,
usually without disrupting the toe alignment. It
is characterized by arthritic pain and limited motion in the joint. Similar to a hallux valgus, a hallux rigidus can
make walking and wearing shoes very painful. Small
bunions are also known to develop on the outside of the foot near the base of the little
toe. These are known as bunionettes, or
“Tailor’s Bunion.”

II. Cause:
The most common cause of hallux valgus bunions is poorly fitted shoes
that are tight, sharply-pointed, or extremely high-heeled.
These shoe-related causes may explain why bunions occur much more frequently
in women than in men. Research has shown that
hallux valgus bunions also have hereditary links. Alternatively,
hallux rigidus bunions are related to arthritis. Arthritic
changes in the joint of the big toe cause a spur to form on the joint, resulting in a
bunion.
III. Treatment and Prevention: The
best way to prevent and alleviate bunion pain is to wear properly fitted shoes that
conform to the shape of the foot. Shoes that
are sufficiently wide, have wide toe boxes, and are low-heeled often provide considerable
relief from bunion pain. In some cases,
women must give up wearing high-heeled shoes altogether.
If deformity from a bunion continues to progress, or pain persists despite changing to
recommended shoe wear, you should seek treatment from an orthopeadic specialist. Surgical treatment of bunions is usually reserved
for cases in which the pain is unresponsive to non-surgical treatments, or in severe
hallux valgus cases, the deformity is so pronounced that it makes fitting shoes difficult. Hallux valgus surgery involves removal of the bone
and re-alignment of the toe and underlying bone. Hallux
rigidus surgery may involve cleaning out the joint, removing part of the bone, or in
extreme cases, fusing the joint. In most
cases, surgery can be done on an outpatient basis, with no hospital stay. |
