Bunions: Genes and shoes both to blame.
The term
"bunion" was derived from a Latin word meaning turnip. This is a
term used to describe a prominence or enlargement at the great toe
joint. On the contrary, this deformity is more than just a bump or
prominence. It involves changes in the structural relationship
between bones on the foot. Sometimes there is no bump at all, but
the abnormal angulation of the first metatarsal bone which causes
the visible prominence. The bone relationships are most appreciated
and easily evaluated on X-ray. Hallux Abducto Valgus (HAV) is the
medical term used to describe this deformity.
There are many
factors that contribute to the development of Hallux Abducto
Valgus. Heredity plays a role in this deformity. Although
bunions are not present at birth, they may develop at an early age.
Most deformities become noticeable during the adult years. This is
because the deformity itself is not inherited but rather a typical
foot type. The mechanics associated with his foot type are to blame.
A flat foot that pronates (rolls in) excessively is more prone to
develop a bunion. Shoes can also be a deforming factor. It is a fact
that HAV was uncommon in Japan until western shoes were introduced.
Also it is noteworthy to mention that HAV is more common in females.
This is a result of the more restrictive, deforming shoes they wear.
Other causes of Hallux Abducto Valgus may include trauma,
neuromuscular disorders, various types of arthritis and ligamentous
disorders.
Individuals with bunions are concerned about the
appearance of their feet but most seek medical attention due to the
painful symptoms. The pain is often due to shoe irritation.
Sometimes there is an associated neuritis or bursitis. Faulty
mechanics and abnormal stresses at the great toe joint will
eventually cause cartilage breakdown. A painful arthritis is often
the end result. This same wear and tear phenomenon occurs at other
weight bearing joints such as the hip and knee. Generally it is safe
to say that the severity and symptoms of this deformity increase
over time.
Conservative treatment is directed at finding
wider, softer shoes that decrease the pressure on the deformity or
first metatarsal head. Bunion pads may also be helpful at relieving
pressure. Since orthotics control foot pronation, they may prove
helpful at halting the progression of this deformity. Some
individuals alter their footwear and their activity and still
experience discomfort. They accept the discomfort because they are
told they'll have to live with it.
Surgical correction of
Hallux Abducto Valgus has been discussed since the turn of
the century. There are many procedures described for the correction
of this deformity. With the test of time, many procedures have
fallen out of favor. For example, the silicon implants used
extensively for joint replacement in the early 1980s are no longer a
panacea. Today they are used only in select cases. Some foot
surgeons choose not to use them at all due to the potential
complications. There are many techniques available to the surgeon
for the correction Hallus Abducto Valgus. There is no one procedure
that can be used to correct all deformities. The selection of a
surgical procedure is based on the severity of the deformity. There
are general guidelines that all foot surgeons must follow in their
selection criteria.
Surgical correction of HAV is an
elective decision made by a patient. Before making this decision, a
patient must be informed of other treatment options. The patient
must understand the risks, benefits and possible complications of
surgery. In addition, the patient must have a thorough understanding
of the postoperative course that they must follow after surgery. The
decision to choose surgery is a very important choice for any
patient. The importance of providing information and educating
patients cannot be over-emphasized. Second opinions can sometimes be
helpful when it comes to making this difficult decision. No matter
which treatment regime is chosen, seeking proper evaluation is the
first step in understanding this deformity and addressing this
problem. Seeking early evaluation is always a good choice as
compared to waiting until the symptoms become severe.
