The physicians of Muir
Orthopaedic Specialists believe good medical care is a result of mutual
understanding, respect and trust. In today's fast paced world, we
recognize the importance of communication and spend as much time as
possible to provide information explaining condition and treatment options
so that our patients can make informed decisions about their care.
DUPUYTREN'S CONTRACTURE
Dupuytren's contracture is a disease affecting
the fascia of the digits and palms. The fascia is not a distinct anatomic
layer, but is instead a collection of specialized fibers which binds the
individual tissue layers together. The fascia is similar to the glue
which holds plywood layers together.
What is the cause of Dupuytren's contracture?
Dupuytren's contracture develops from normal
fascia and the cause is unknown. There is probably a genetic basis for
the disease. For example, there is a strong association in men whose
ethnic background is from Northern European countries.
Prevention
Molecular investigation has identified
specialized cells that may control the growth of Dupuytren's contracture.
An active metabolic process at the cellular level may cause normal fascia
to become diseased. Surgical removal of the fascia does not disrupt or
prevent the cellular activity and the disease can progress. Future
investigation involves finding medication which blocks the activity
of the cells. Presently, there is no method to prevent Dupuytren's
contracture.
Clinical Features
The first sign is the presence of small
nodules in the palm of the hand, which feel like hard lumps. Over several
months or years, the nodules can coalesce and grow together to form long
bands called cords. As the cords become further diseased, they can bend
the fingers down, resulting in the inability to fully straighten the
finger, which is called contracture. The cords will typically affect the
ring and small fingers, and in some individuals can affect all of the
digits. Dupuytren's nodules and cords are usually not painful, but the
loss of motion can interfere with activities.
Dupuytren's contracture represents a benign
disease and usually does not spread to other areas. Certain patients can
develop cords and nodules on the soles of their feet and Dupuytren's
contracture can rarely be associated with other illnesses, such as
diabetes and alcoholism.
The natural history and the extent of the
Dupuytren's contracture is extremely variable. Some patients develop
small nodules which do not interfere with any activities and experience no
further progression. Other patients develop nodules which rapidly
progress to cords, resulting in severe contraction to the effected
fingers. Why this rapid progression occurs in some individuals is not
known. Dupuytren's contracture in women and in those individuals less
than 40 is felt to represent a more severe form and contractures are
considered more likely in these individuals.
Treatment
Surgery is the most effective treatment.
Surgery is postponed until the finger loses approximately 20-30 degrees of
motion and the patients can no longer place their hands flat on a table
top. Surgery is usually performed as an outpatient. The skin overlying
the diseased cord is incised in a zig-zag
fashion. The tendons, nerves and blood vessels are identified and
protected, and the diseased fascia is surgically removed. Any surrounding
fascia which is obviously diseased is also removed. Surgery to remove
normal fascia has not been helpful and does not seem to affect the
progression of further contractures. Therefore, the surgery is limited to
removing the diseased tissue. Surgery can be very meticulous in order to
protect the delicate neurovascular structures, while removing all of the
diseased fascia.
Outcome
The outcome following surgery is highly
dependent on individual circumstances. Surgery can be extensive and
requires several weeks to a few months of postoperative recovery.
Patients will typically require hand therapy. This includes the use of
specialized splints and supervised therapy in order to regain motion and
strength. Most patients are able to resume normal daily activities within
a few weeks. Vigorous activities such as sports may require several
months of recovery.
There can be a recurrence of Dupuytren's
contracture in about 30 percent of patients within five years of surgery.
The reason for this recurrence is not clearly known. It usually does not
recur to the same extent that initially required surgery and additional
treatment is usually not necessary. In the event that the disease
progresses to require additional surgery, then not only is the diseased
fascia removed, but sometimes the overlying skin is surgically removed and
replaced with skin graft.
Your physician can provide additional details
on an individual basis.
