Card 1
Question: What is Dupuytren's disease in one sentence?
Answer: A benign fibromatosis of the palmar and digital fascia of the hand causing nodules and cords that can lead to flexion contractures.
Card 2
Question: Where does Dupuytren’s disease typically begin anatomically?
Answer: With a palpable mass (Dupuytren’s nodule) in the palm, usually at the level of the distal palmar crease.
Card 3
Question: What is a Dupuytren’s nodule and how can it present?
Answer: A palpable mass in the palm that may be transient and mildly painful and can enlarge into pathologic cords.
Card 4
Question: How do Dupuytren’s cords cause joint deformity?
Answer: As cords thicken and shorten they produce flexion contractures of the affected joints.
Card 5
Question: Which fingers are most commonly involved in Dupuytren’s disease?
Answer: The fourth and fifth digits are most commonly involved, but the thumb, first web, index, and long finger can also be affected.
Card 6
Question: How does disease on the radial side of the hand differ epidemiologically?
Answer: Disease on the radial side of the hand is more common in diabetic patients.
Card 7
Question: What is Dupuytren’s diathesis and which patient features define it?
Answer: A subgroup with higher recurrence and multiple surgeries defined by caucasian race with positive family history, bilateral disease, ectopic lesions (l
Card 8
Question: What key elements are included in the diagnostic work-up for Dupuytren’s disease?
Answer: Careful patient history and physical examination, recording contractures with a digital goniometer, and performing the table top test.
Card 9
Question: What is the table top test in Dupuytren’s disease used to detect?
Answer: It detects fixed joint contractures by assessing whether the patient can place the palm flat on a table (positive indicates contracture).
Card 10
Question: How can contracture measurements vary with joint position in Dupuytren’s disease?
Answer: Dynamic contractures can change with joint position—for example, a central cord crossing MP and PIP joints shows greater PIP extension lag when the MP
