Dupuytren's contracture affects which tissue?

• A. Palmar aponeurosis
• B. Palmar fascia
• C. Dorsal fascia
• D. Flexor tendons

Answer: (B)

Dupuytren's contracture is a fibrosing process of the palmar fascia—the thick connective tissue in the palm that forms the palmar aponeurosis. This fibrous tissue undergoes nodular proliferation and later cord formation, causing contractures that pull the fingers into flexion, often affecting the ring and little fingers. The issue is rooted in the palm’s connective tissue, not the dorsal fascia or the flexor tendons themselves (though the fascia can restrict tendon movement as it tightens). Therefore, the tissue primarily involved is the palmar fascia.
