Hand FAQ

Question:

As my Aunt Loretta used to say, "Shoot a bean." This means I can't make up my mind about the best way to treat my two stuck fingers. The doc says I have a disease called Dupuytren. Middle joints of the middle and ring fingers of my dominant hand are stuck in a bent position. The choices for treatment are some kind of enzyme injection or surgery. Both sound simple and successful. Are there any tipping points to help me with this one?

Answer:

You may be interested in the results of a study recently reported by a group of surgeons at the Philadelphia Hand Center at Thomas Jefferson Medical College. In this study, surgeons from the report on the effect of a three-part therapy treatment for severe Dupuytren disease. Patients enrolled included 19 men and two women ranging in age from 37 to 80 years old. All had one or more proximal interphalangeal (PIP or middle) joints stuck in flexion of at least 40 degrees or more. Twenty-two proximal interphalangeal (PIP) joints received one standard collagenase injection followed by manual cord rupture (performed by the surgeon). Then they were treated by a hand therapist. The hand therapy consisted of wearing a custom-made splint (dorsal hand-based extension orthosis) at night and special exercises delivered and supervised by the therapist but also performed by the patient throughout the day at home. For day use, the hand orthosis was replaced by a smaller, finger splint to hold the PIP joint in full extension (straight). Results measured by change in finger motion were impressive. Patients went from having severe flexion contractures (range of 40 to 80 degrees) down to zero for some patients (a range from zero to 55 degrees among all 22 fingers). A contracture means the finger is stuck and cannot move. A flexion contracture gives us the clinical picture that the patient's finger is bent by the amount of degrees mentioned and cannot straighten. The positive results of this study are important for two reasons. First, there is no known "cure" for Dupuytren disease and second, the proximal interphalangeal (PIP) joint does not respond well to treatment. When the metacarpophalangeal (MCP) joints are primarily involved, treatment has been quite successful. But with the PIP joints, treatment in the past has not been as successful. This may be because contractures of the PIP joints also affect the collateral ligaments (on each side of the finger joint), the volar plate, and cause adhesions inside the joint. The volar plate is actually a very thick ligament that prevents hyperextension of the joint. This ligamentous structure also reinforces the joint capsule and gives the joint greater stability. In viewing the results of this treatment compared to other studies utilizing surgery and postoperative splinting, there was an 88 per cent improvement in the patients who received this protocol of collagenase injection, manipulation, splinting, and exercises. This compared to a 44 per cent improvement with surgical intervention and splinting for the same problem. Despite these good results, the authors warn that problems can develop using collagenase injections. The enzymes in the injection can eat away and dissolve more than just the contracted tissue. Tendons and tendon pulleys may be adversely affected by these effects. The use of only one collagenase injection followed by carefully supervised hand therapy may have made the difference in success rates observed in this group of patients. Given this information, a one-on-one discussion with your surgeon about the pros and cons of each treatment for your hand may be the next step. Terri M. Skirven, BS, et al.
