A Non-Surgical Option for Bent Fingers

Dupuytren's contracture is a condition that causes the fingers to be pulled into a clenched position. Dupuytren's contracture occurs in hundreds of thousands of Americans and millions of people worldwide. The condition prevents those affected from being able to fully straighten their fingers, and severity can range from very mild with mostly normal finger mobility to severe cases where fingers become stuck in the palm of the hand.

Dupuytren's contracture is a manifestation of Dupuytren's disease, a syndrome that can also cause contractures of the soft-tissues on the sole of the feet (Lederhose disease) or, in men, in the penis (Peyronie's disease). There is no known cure for Dupuytren's disease, and little is understood about the cause of this condition. Until recently, there were also very few treatment options for patients who suffer from these conditions.

Collagenase Injections

Collagenase has emerged as a useful treatment for some patients with Dupuytren's contracture. The type of tissue that contracts in the palm and fingers is made of collagen. The contracture forms both nodules and cords that pull the fingers in to the palm. Collagenase is an enzyme that is produced by a bacteria called Clostridium histolyticum, and this enzyme eats away at collagen, causing it's structure to weaken. Collagenase is extracted from the bacteria, and injected into the Dupuytren's cords by your doctor. One day after the injection, after the enzyme has done it's work, you return to the doctor to have the finger manipulated to break up the tightened tissue, and restore finger mobility.

The collagenase injection is sold under the trade name Xiaflex. It comes prepackaged in a syringe that is delivered directly to your treating doctor. Any doctor can become certified to administer Xiaflex injections, but this is commonly done by orthopedic surgeons, hand surgeons, and rheumatologists.

Treatments for Dupuytren's Contracture

Until recently, the only options for treatment of Dupuytren's contracture were observation or surgery. Because the surgery is highly invasive, and can involve protracted rehabilitation, most doctors recommended waiting as long as possible, then having surgery when absolutely necessary. Things have changed, and as less-invasive treatments have become available, many doctors are trying to treat Dupuytren's contracture in the earlier stages, to prevent progression to a more severe deformity that is much harder to correct.

In general, there are four treatment options for Dupuytren's contracture:

  • Observation: Observation is the standard initial treatment for Dupuytren's. Most people with minimal contractures are not bothered by the condition, and if there is slow progression, then treatment may not be needed. These patients may have their condition regularly monitored to assess for progression.
  • Needle Aponeurotomy: Needle aponeurotomy has been performed in Europe for several decades, and has become more popular in the US over the last ten years. In this procedure, your doctor uses the tip of a needle to carefully break up the cords of tissue to allow the finger to straighten. Large incisions are not needed. Some doctors and patients prefer this procedure because it is by far the least expensive of the treatments (other than observation), and can often be done in only one visit, with minimal recuperation.
  • Collagenase: Collagenase injections have become more popular since 2010 when the FDA approved the first medication for this use in the United States. Collagenase is sold under the trade name Xiaflex, and must be injected by a certified physician who has been trained in the use of the medication. Collagenase injections are expensive (over $3000 per vial), and may require more than one vial of medication in more extensive contractures. That said, this treatment is almost always less expensive than having surgery.
  • Surgery: As stated, until recently, surgery was the only treatment available for Dupuytren's contracture. While surgery is often the best treatment for more severe contractures, there are some downsides. Surgery is more invasive, more painful, and often involves a much longer rehabilitation than less-invasive options. That said, less-invasive options tend to do best in patients with mild to moderate contractures whereas results after more severe deformities are often better treated with surgery. In addition, surgery has been shown to provide longer lasting relief, with a longer time until recurrence of deformity.

Which Is Best?

There really is no 'best treatment,' as all of these options have pros and cons. Certainly, if a less-invasive option is appropriate, then most patients will prefer such options. Unfortunately, some patients require more extensive treatment, and in those cases, surgery may be the best choice. Whatever option you choose, it is important to identify a physician who uses the treatment regularly, and has regular experience with the chosen procedure. Some doctors are skilled in more than one technique, but often if you want to compare options, you will have to see more than one doctor.

I always tell my patients, that no matter what treatment is chosen, patients need to understand there is at present no cure for Dupuytren's disease, only treatments for the manifestations of the condition (the contracture). Therefore, no matter what treatment is performed, recurrence of the contracture is likely. Recurrence after needle aponeurotomy is an average of 3 years, after surgery the average is 5 years. There is not enough data at this time to know how well collagenase injection treatments will do in terms of recurrence rate.
