Here are some practical points which are considered in choosing the best treatment:
The
worse the contracture, the less likely treatment will result in a a full correction, but treatment is
always possible.
The outlook depends on which joints are involved. Doctors use specific words to indicate specific joints: The
distal interphalangeal, or
D.I.P. joint is the end finger joint. The
proximal interphalangeal, or
P.I.P. joint is the knuckle in the middle of the finger. The
metacarpophalangeal, or
M.C.P. joints are the big knuckles that you see on the back of your hand when you make a fist - the knuckles in a "knuckle sandwich"
Contractures which only affect the MCP joint are most predictably helped by either needle aponeurotomy or surgery.
Contractures which only affect the PIP joint are the most likely to
recur after treatment, especially in the pinky finger. They may be
treated with either needle aponeurotomy or surgery.
Contractures which affect both the MCP and PIP joints actually have a better outlook than isolated PIP contractures. They may be
treated with either needle aponeurotomy or surgery.
Contractures which affect both the PIP and DIP joints have a similar
outlook as combined contractures - unless the finger develops a
backwards bend of the DIP joint - called a "boutonniere" deformity.
Boutonniere deformity from Dupuytren's has a higher recurrence rate
than other patterns of involvement. This may be
treated with either needle aponeurotomy or surgery.
Contractures due to well defined
cords - which feel
like a thick string under the skin - are usually good candidates for
either needle aponeurotomy or surgery. When there is not a clear cord,
but a general tightness, it is referred to as
diffuse disease.
Needle procedures may not be possible in some cases of diffuse disease,
and the most appropriate treatment may invove skin grafting.
Usually, the skin near a cord is nearly as soft as skin in unaffected
areas of the palm. Sometimes the skin is hard or leathery over a wide
area, referred to as
tethered skin. If this is so, needle aponeurotomy may or may not be possible, and the most appropriate treatment may invove skin grafting.
If Dupuytren's recurs in areas of previous surgery, it is common
to have diffuse disease, tethering, or both problems. If so, needle
aponeurotomy may or may not be possible, and the most appropriate
treatment may invove skin grafting.
