Dupuytren's contracture (also known as morbus Dupuytren, or Dupuytren's disease and slang terms "Viking disease" or "Celtic hand), is a fixed flexion contracture of the hand due to a palmar fibromatosis, where the fingers bend towards the palm and cannot be fully extended (straightened). It is an inherited proliferative connective tissue disorder that involves the hand's palmar fascia. It is named after Baron Guillaume Dupuytren, the surgeon who described an operation to correct the affliction in the Lancet in 1831.
The ring finger and little finger are the fingers most commonly affected. The middle finger may be affected in advanced cases, but the index finger and the thumb are not affected as frequently. Dupuytren's contracture progresses slowly and is often accompanied by some aching and itching. In patients with this condition, the palmar fascia thickens and shortens so that the tendons connected to the fingers cannot move freely. The palmar fascia becomes hyperplastic and contracts.
Incidence increases after age 40; at this age, men are affected more often than women. Beyond 80 the gender distribution is about even.

Signs and symptoms
In Dupuytren's contracture, the palmar fascia within the hand becomes abnormally thick, which can cause the fingers to curl and can impair finger function. The main function of the palmar fascia is to increase grip strength; thus, over time, Dupuytren's contracture decreases patients' ability to hold objects. Patients often report pain, aching and itching. Those patients report pain along with the contractions.
Dupuytren's disease often starts with nodules in the palm of the hand and it can extend to a cord in a finger.
- Peyronie's disease - curvature of the penis
- Plantar fibromatosis - callus under the foot and possible curling under of toes
- Garrod's pad - pads on the back of knuckles of fingers
- Frozen shoulder - shoulder that develops stiffness and limited range of motion
Suspected, but unproven, causes of Dupuytren's contracture include trauma, diabetes, epilepsy and therapy with phenytoin. No proven evidence links hand injuries or specific occupational exposures to a higher risk of developing Dupuytren’s. Some speculation links the condition or its onset may be triggered by, physical trauma such as sustained manual labor or over-exertion of the hands. However, the fact that Dupuytren's is not connected with handedness undermines this claim.
Dupuytren's contracture is a non-specific affliction, but primarily affects:
- People of Scandinavian or Northern European ancestry; it has been called the "Viking disease" or "Celtic hand", though it is also widespread in some Mediterranean countries (e.g., Spain and Bosnia) and in Japan;
- Men rather than women (men are ten times as likely to develop the condition);
- People over the age of 40;
- People with a family history (60% to 70% of those afflicted have a genetic predisposition to Dupuytren's contracture);
- Rock climbers
The palmar fascia becomes abnormally thick due from a change of collagen type. Normally, the palmar fascia consists of collagen type I, but in Dupuytren sufferers, the collagen changes to collagen type III, which is significantly thicker than collagen type I. The contracture sets in slowly.
Treatment is indicated when the so-called table top test is positive. With this test, the patient places his hand on a table. If the hand lies completely flat on the table, the test is considered negative. If the hand cannot be placed completely flat on the table, leaving a space between the table and a part of the hand as big as the diameter of a ballpoint pen, the test is considered positive and surgery or other treatment may be indicated. Additionally, finger joints may become fixed and rigid. Treatment using radiation therapy begins at an earlier stage. Radiation therapy is most effective when nodules and cords first appear, and before contracture begins.
The initial description of Dupuytren’s disease diathesis included 4 factors:
- the patient is below the age of 50 years old
- positive family history
- both of the hands are affected
- ectopic lesions (Peyronie's disease, Knuckle pads and Ledderhose disease).
Hindocha et al. reevaluated these 4 factors and modified them. Two additional factors were added: male gender and age at onset below 50 years.
Treatment involves one or more different types of treatment with some hands needing repeated treatment.
Radiation Therapy is effective at the early nodules and cords stage "Stage N" and also used at the N/I stage of 10 degrees or less of deformation.
Needle Aponeurotomy is most effective at "Stage I" of 6-45 degrees of deformation. It is also used at less than 6 degrees and more than 45 degrees of deformation.
Collagenase Injection (Xiaflex) is most effective at "Stage I". It is also used at "Stage II" of 46-90 degrees of deformation.
Hand Surgery is effective at Stages I- Stage IV.
Early Stage: Radiation Therapy
Dupuytren’s may be treated at the nodules, cords and early finger deformation stages with Radiation therapy.
Finney first reported the effects of radiation treatment in the British Journal of Radiology in 1955.
In Germany and parts of the U.S., radiotherapy is one of the main treatments. A global list of clinics offering radiation treatment for Dupuytren's and Ledderhose is maintained by the International Dupuytren Society.
In a 2012 study, Seegenschmiedt et al. showed comparisons with a control group.
Radiotherapy has been reported to be effective for prevention of disease progression in early stages with only mild acute or late side effects.
The effect of radiation therapy on a long-term outcome was evaluated by Betz et al. They conducted a follow up evaluation 13 years later for patients receiving radiation therapy. Treatment toxicity and objective symptom reduction in terms of stage change and numbers of nodules and cords were assessed. They concluded that radiotherapy is effective in prevention of disease progression and improves patients' symptoms in stage N, N/I. Given disease progression after radiotherapy, a "salvage" operation is still possible according to the authors.
The UK National Institute for Health and Care Excellence published guidelines and approval in November 2010. The guidance proposed a single phase of 15 grays (Gy) of treatment as standard for non severe cases.
HM Seegenschmiedt, who began treating Dupuytrens with radiotherapy in 1987, presented his findings at the 2010 International Symposium on Dupuytren's Disease in Miami, USA.
Seegenschmiedt stated that radiotherapy is an early stage treatment in which finger deformation should be 10 degrees or less. The most preferable state would be no deformation, with the hand diagnosed as an "active" state, in which nodules and cords are changing. During diagnosis the feet are checked for Ledderhose disease.
The nodules and cords are irradiated for five days in a row with a dose of 3 Gy fractions per day, totaling 15 Gy for the week. The treatment is repeated after 12 weeks.
The purpose of radiotherapy is to stop disease progression. It has a documented success rate of 85%.
The cell responsible for the disease is the myofibroblast. Liaquat S. Verjee et al. excised myofibroblasts from patients with the disease to explore the signaling pathways for their formation. They found significant numbers of immune cells, including classically activated macrophages and high levels of proinflammatory cytokines. They compared the effects of these cytokines on contraction and profibrotic signaling pathways in fibroblasts from the palmar and nonpalmar dermis of patients and palmar fibroblasts from controls. Addition of tumor necrosis factors (TNF), but not other cytokines, promoted differentiation of fibroblasts into myofibroblasts in Dupuytren's patients. Neutralizing antibodies to TNF inhibited the contractile activity of myofibroblasts, reduced their expression of α-smooth muscle actin, and mediated disassembly of the contractile apparatus.
In 1831 Dupuytren was the first to describe Dupuytren’s disease and a surgical procedure. The procedure he described was a minimally-invasive needle procedure. Because of high recurrence rates, new surgical techniques were introduced, such as the fasiectomy and then the dermofasciectomy. Most of the diseased tissue is removed with these procedures. Recurrence rates are high. For some individuals, the partial insertion of "K wires" into either the DIP or PIP joint of the affected digit for a period of a least 21 days to fuse the joint is the only way to halt the disease's progress. After removal of the wires, the joint is fixed into flexion, which is considered preferable to fusion at extension.
The patient burden after open surgery is high, therefore less invasive techniques may be preferred. New studies have been conducted for percutaneous release, extensive percutaneous aponeurotomy with lipografting and collagenase. These treatments show promise. Several alternate therapies such as vitamin E treatment, have been studied, although without control groups. Most doctors do not value those treatments. None of these treatments stop or cure the condition permanently. In extreme cases, amputation of fingers may be needed for severe or recurrent cases, or after surgical complications.
During the procedure the patient is under regional or general anesthesia. A surgical tourniquet prevents blood flow to the limb. The skin is often opened with a zig-zag incision but straight incisions with or without Z-plasty are also described- and may reduce damage to neurovascular bundles. All diseased cords and fascia are excised. The excision has to be very precise to spare the neurovascular bundles. Because not all the diseased tissue is visible macroscopically, complete excision is uncertain. A 20-year review of surgical complications associated with fasciectomy showed that major complications occurred in 15.7% of cases, including digital nerve injury (3.4%), digital artery injury (2%), infection (2.4%), hematoma (2.1%), and complex regional pain syndrome (5.5%), in addition to minor complications including painful flare reactions in 9.9% of cases and wound healing complications in 22.9% of cases. After the tissue is removed, the surgeon closes the incision. In the case of a shortage of skin, the transverse part of the Zig-Zag incision is left open. Stitches are removed 10 days after surgery.
After surgery the hand is wrapped in a light compressive bandage for one week. Patients start bending and extending their fingers as soon as the anesthesia has resolved. Hand therapy is often recommended. Approximately 6 weeks after surgery patients are able to completely use their hand.
The average recurrence rate is 39% after a fasciectomy after a median interval of about 4 years.
Three centres worldwide have published the results of limited/selective fasciectomy under local anesthesia (LA) with epinephrine but no tourniquet. In 2005 Denkler described the technique. His 60 cases refuted several decades of surgical dogma that adrenaline cannot be used in digits, and that Dupuytren's fasciectomy cannot be done under LA without a tourniquet. In 2009 Lalonde described a multicentre comparative study of 111 cases having surgery under general or local anesthesia with equivalent results. In 2012, orthopedic surgeons MSK & QMK Bismil described the first high volume awake Dupuytren's service for 270 cases. Their One Stop Wide Awake surgery (OSWA) required one thirty to forty-five minute management slot involving outpatient LA surgery. Patients were taught range-of-motion exercises during the procedure and the surgeon used dynamic information to optimize the surgery. Accelerated rehabilitation can eliminate splinting. A modified boxing-glove bandage can prevent significant post-operative hematoma.
Operating without a tourniquet is the only (comfortable) option for a wide awake patient, but is contrary to most hand surgeons' training. As of 2014 the technique was only routinely available from Robbins in Australia, Denkler in the US, Lalonde in Canada or Bismil in the UK. The largest series of wide awake fasciectomy utilizes the skin incisions described by Robbins, with or without deferred Z-plasty, with greater patient safety and protection for the neurovascular bundle (straight incisions).
Dermofasciectomy is a surgical procedure that is mainly used in recurrences and for patients with a high chance of recurrence. Just like the limited fasciectomy, the dermofasciectomy excises diseased cords, fascia and the overlying skin. The skin is then closed with a skin graft, usually full-thickness, consisting of the epidermis and the entire dermis. In most cases the graft is taken from the elbow flexion crease or the proximal inner side of the arm. This place is chosen, because the skin color best matches the palm's skin color. The skin on the proximal inner side of the arm is thin and has enough skin to supply a full-thickness graft. The donor site can be closed with a direct suture.
The graft is sutured to the skin surrounding the wound. For one week the hand is protected with a dressing. The hand and arm are elevated with a sling. The dressing is then removed and careful mobilization can be started, gradually increasing in intensity. After this procedure the recurrence of the disease can be low but the re-operation and complication rate may be high.
Free Vascular Flaps
In severe cases a free vascular flap may be preferred and is thought to reduce recurrence. A one-year follow-up of a single patient was described. This patient had not experienced recurrence.
Segmental Fasciectomy with/without Cellulose
Segmental fasciectomy involves excising part(s) of the contracted cord so that it disappears or no longer contracts the finger. It is less invasive than the limited fasciectomy, because not all the diseased tissue is excised and the skin incisions are smaller.
The patient is placed under regional anasthesia and a surgical tourniquet is used. The skin is opened with small curved incisions over the diseased tissue. If necessary, incisions are made in the fingers. Pieces of cord and fascia of approximately one centimeter are excised. The cords are placed under maximum tension while they are cut. A scalpel is used to separate the tissues. The surgeon keeps removing small parts until the finger can fully extend. Patients start with active mobilization the day after surgery. They wear an extension splint for two to three weeks, except during physical therapy.
The same procedure is used in the segmental fasciectomy with cellulose implant. After the excision and a careful haemostasis, the cellulose implant is placed in a single layer in between the remaining parts of the cord.
After surgery patients wear a light pressure dressing for four days, followed by an extension splint. The splint is worn continuously during nighttime for eight weeks. During the first weeks after surgery the splint may be worn during daytime.
Percutaneous Needle Fasciotomy
Needle aponeurotomy is a minimally-invasive technique where the cords are weakened through the insertion and manipulation of a small needle. The cord is sectioned at as many levels as possible in the palm and fingers, depending on the location and extent of the disease, using a 25 Gauge needle mounted on a 10 ml syringe. Once weakened, the offending cords can be snapped by putting tension on the finger(s) and pulling the finger(s) straight. After the treatment a small dressing is applied for 24 hours. After these 24 hours patient are able to use their hands normally. No splints or physiotherapy are given.
The advantage of needle aponeurotomy is the minimal intervention without incision (done in the office under local anesthesia) and the very rapid return to normal activities without need for rehabilitation, but the nodules may resume growing. A study reported postoperative gain is greater at the MCP-joint level than at the level of the IP-joint and found a reoperation rate of 24%; complications are scarce. Needle aponeurotomy may be performed on fingers that are severely bent (stage IV), and not just in early stages. A 2003 study showed 85% recurrence rate after 5 years.
Extensive Percutaneous Aponeurotomy and Lipografting
A technique introduced in 2011 is extensive percutaneous aponeurotomy with lipografting. This procedure also uses a needle to cut the cords. The difference with the percutaneous needle fasciotomy is, that the cord is cut at many places. The cord is also separated from the skin to make place for the lipograft that is taken from the abdomen or ipsilateral flank. This technique shortens the recovery time. The fat graft results in supple skin.
Before the aponeurotomy, a liposuction is done to the abdomen and ipsilateral flank to collect the lipograft. The treatment can be performed under regional or general anesthesia. The digits are placed under maximal extension tension using a firm lead hand retractor. The surgeon makes multiple palmar puncture wounds with small nicks. The tension on the cords is crucial, because tight constricting bands are most susceptible to be cut and torn by the small nicks, whereas the relatively loose neurovascular structures are spared. After the cord is completely cut and separated from the skin the lipograft is injected under the skin. A total of about 5 to 10 ml is injected per ray.
After the treatment the patient wears an extension splint for 5 to 7 days. Thereafter the patient returns to normal activities and is advised to use a night splint for up to 20 weeks.
As of 2011 this treatment was performed only in Miami or Rotterdam. Prospective randomized comparative studies were in process.
Clostridial collagenase is a pharmaceutical treatment option. The cords are weakened through the injection of small amounts of the enzyme collagenase, which breaks peptide bonds in collagen.
The treatment with collagenase is different for the MCP joint and the PIP joint. In a MCP joint contracture the needle must be placed at the point of maximum bowstringing of the palpable cord. The treatment consists of one injection with 0.58 mg 0.25 ml. collagenase clostridium histolyticum (CCH).
The needle is placed vertically on the bowstring. The collagenase is distributed across three injection points. For the PIP joint the needle must be placed not more than 4 mm distal to palmar digital crease at 2–3 mm depth. The injection for PIP consists of one injection filled with 0.58 mg CCH 0.20 ml. The needle must be placed horizontal to the cord and also uses a 3-point distribution. After the injection the patient’s hand is wrapped in bulky gauze dressing and must be elevated for the rest of the day. After 24 hours the patient returns for passive digital extension to rupture the cord. Moderate pressure for 10–20 seconds ruptures the cord.
After the treatment with collagenase the patient should use a night splint and perform digital flexion/extension exercises several times per day for 4 months.
A study where patients were treated with these collagenase injections showed a recurrence rate of 67% in the MCP joint and 100% in the PIP joint. Although these recurrent rates are high, the recurrence was not as severe as the primary occurrence. Collagenase injection is a nonsurgical option to treat Dupuytren’s disease and it provides the benefits of avoiding the potential surgical complications such as nerve injury, hematoma and skin necrosis. Primary surgery reports a 5% incidence of nerve injury and 12% in second surgery.
In February 2010 the US Food and Drug Administration (FDA) approved injectable collagenase extracted from Clostridium histolyticum for the treatment of Dupuytren's contracture. The treatment is marketed under the tradename Xiaflex. In February 2011, the European Commission's Committee for Medicinal Products for Human Use approved the preparation for use in Europe, where it is marketed under the tradename Xiapex.
Laser treatment (using red and infrared at low power) was informally discussed in 2013 at an International Dupuytren Society forum, as of which time little or no formal evaluation of the techniques had been completed.
Only anecdotal evidence supports other compounds as beneficial for Dupuytren's patients.
- Acetylcarnitine Hcl
- Para amino benzoic acid
- Vitamin E This was investigated in the 1940s
- Vitamin C
Various forms of bodywork/massage also have only anecdotal support.
Dupuytren’s disease has a high recurrence rate, especially when a patient has so called Dupuytren’s diathesis. The term diathesis relates to certain features of Dupuytren's disease and indicates an aggressive course of disease.
The presence of all new Dupuytren’s diathesis factors in a patient increases the risk of recurrent Dupuytren’s disease by 71% compared with a baseline risk of 23% in patients lacking the factors. In another study the prognostic value of diathesis was evaluated. They concluded that presence of diathesis can predict recurrence and extension. A scoring system was made to evaluate the risk of recurrence and extension evaluating the following values: bilateral hand involvement, little finger surgery, early onset of disease, plantar fibrosis, knuckle pads and radial side involvement.
Minimally invasive therapies may precede higher recurrence rates. Recurrence lacks a consensus definition. Furthermore, different standards and measurements follow from the various definitions.
Postoperative care involves hand therapy and splinting. Hand therapy is prescribed to optimize post-surgical function and to prevent joint stiffness.
Besides hand therapy, many surgeons advise the use of static or dynamic splints after surgery to maintain finger mobility. The splint is used to provide prolonged stretch to the healing tissues and prevent flexion contractures. Although splinting is a widely used post-operative intervention, evidence on its effectiveness is limited, leading to variation in splinting approaches. Most surgeons use clinical experience to decide whether to splint. Cited advantages include maintenance of finger extension and prevention of new flexion contractures. Cited disadvantages include joint stiffness, prolonged pain, discomfort, subsequently reduced function and edema.
A third approach emphasizes early self-exercise and stretching.
Society and culture
The International Dupuytren Society was founded in Germany in 2003. It is a non-profit organization based in Germany where patients and medical experts cooperate, without promoting specific treatment. Stated goals are informing the public about Dupuytren's Contracture and treatment options, and supporting research, patients and organizations. It publishes reliable medical results, and provides a discussion forum for practitioners and patients.
