What
is Dupytrens disease?
Dupuytren's
disease is named after Baron Guillaume Dupuytren,, a famous French
surgeon who practised in Paris in the 18th century.

It
is a disease of the fascia or connective tissue that lies below
the skin of the palm. This fibrous tissue is designed to immobilise
the skin of the palm to aid grip in comparison to the more mobile
skin on the back of the hand.
In
Dupuytren's disease, the normal fascia becomes thickened and forms
cords in the palm and the fingers resulting in the fingers becoming
fixed in a bent position. It usually begins at the age of 40-50
years but may occur in younger patients, particularly when it runs
in the family.
What
causes Dupytrens disease?
The
cause is unknown. It runs in families, particularly those of Celtic
or northern European origin. It is more common in men than women.
It occurs more frequently in those with diabetes and those on anti-epileptics.
It also occurs more frequently in those with a high alcohol intake.
Various biochemical abnormalities have been found in this condition
but the exact cause and any method of prevention are unknown. It
is not related to manual work.
What
are the features?
The first sign is usually a tender nodule in the palm. The nodule
is only painful for several weeks at the onset. The disease is painless
after this. The nodule may gradually form a thickened cord under
the skin and extend along the palm into the finger, or a new nodule
or cord may develop elsewhere in the same or opposite hand.
The
rate at which the disease develops varies enormously from person
to person. When it begins very late in life it tends to progress
very slowly and may never be a problem. When it occurs in younger
patients, particularly those with in which the disease runs in the
family, it may be very aggressive, causing the fingers to bend down
in a flexed position due to the contracting cords of fibrous tissue.
The ring and small fingers are most commonly affected.
On
rare occasions it may affect the soles of the feet with thickened
painless nodules.

How is it
treated?
At
present surgery is the only way to treat this condition and there
is no known way of preventing it or slowing its progress. Research
is being performed on the use of collagenase (an enzyme which dissolves
connective tissue) injections to rupture the cords of Dupuytren's
tissue as an alternative to surgery. This treatment is not yet available
in Australia and its use is limited to certain cases.
Surgery
is generally indicated when the finger becomes bent or contracted
to a point where the palm or the hand can no longer be placed flat
on a table or other flat surface.
Surgery
involves removing the diseased tissue from the hand using multiple
zigzag incisions.
Following
surgery the hand is place in a splint to keep the fingers in the
straightened position. Small drains may be used to prevent blood
collecting under the skin. These are removed the day after surgery.
The sutures are removed 10-14 days after surgery. Therapy is commenced
in 3-4 days to prevent the fingers from becoming stiff. A splint
may be worn for several weeks between exercises to maximise the
correction of the finger deformities.
In
severe disease or when surgery has been performed in the same area
previously, skin grafts may be required. If this is likely, your
surgeon will discuss it prior to your operation.

Expected
Results
Despite
surgery, the Dupuytren's tissue can reappear in the same place (recurrence)
or occur in other parts of either hand (extension of the disease).
Unfortunately trauma such as injury to the hand or surgery to treat
the condition itself, may lead to increased activity and progression
of the disease. This is particularly common in those with an aggressive
form of the disease (young age at onset, strong family history,
rapid progress of contracture).

Dupuytren's disease in the finger, causing
the nerve and artery to be displaced from their normal course.
Problems
that can occur with the surgery include difficulty with wound healing
and small areas of skin loss where the diseased tissue has been
removed and left very thin areas of skin. Blood clots (haematoma)
can collect under the skin and on rare occasion these may become
infected. Occasionally nerves and arteries can be injured as they
may be trapped or tethered by the Dupuytren's tissue.
In
most cases it is possible to completely straighten the "knuckle"
or metacarpophalangeal joint. Full correction of the contracture
in the smaller joints of the finger is not usually possible, but
the degree of contracture can be improved in most cases. This sometimes
requires more extensive surgery to release the joint. In severe
cases, a temporary wire may be placed across the joint to keep it
straight for 3-4 weeks following the surgery or occasionally a joint
may be fused (permanently stiffened) to prevent it becoming bent
again.
