Patient Story
A 53-year-old man presented with stiffness in his hands. He said his hands began to feel stiff several years ago, and now he finds that he cannot straighten many of his fingers (Figure 107-1). He delayed seeing a physician because he did not feel any pain in his hands. He recently began having difficulty holding his woodworking tools and wants to regain the function he has lost in his hands. The physician diagnosed him with Dupuytren contracture and discussed the disease with him along with his options for treatment.
Introduction
Dupuytren contracture is a flexion contracture of one or more of the fingers in the hand. Patients develop a progressive thickening of the palmar fascia, which causes the fingers to bend in toward the palm and limits extension. Diagnosis is clinical and the palpable nodules in the palm are considered diagnostic. Treatment has historically been surgical, but a new nonsurgical treatment with a collagenase has been approved.

Epidemiology
- Dupuytren contracture is an autosomal dominant disease with incomplete penetrance (Figure 107-2).
- Higher prevalence among whites, particularly of Northern European descent. There is an increasing incidence related to aging.5
- More common in men than women (approximately 6:1).1,3
- Incidence in the United States is estimated to be approximately 3 per 10,000 adults with an estimated prevalence of 7%.
- Higher incidence in people who use tobacco and alcohol or who have diabetes mellitus or epilepsy.2
Etiology and Pathophysiology
- Myofibroblasts in the palmar fascia proliferate to form nodules.
- Myofibroblasts then align along the lines of tension, forming cords.
- Tissue becomes acellular leaving thick cords of collagen that tighten resulting in flexion contractures at the metacarpal phalangeal joint, the proximal interphalangeal joint, and, occasionally, the distal interphalangeal joint.
