**Question:** All are true of Dupuytren's contracture except -

A. It is a rare disease affecting the elderly population
B. It is primarily caused by trauma
C. It is a neurological disease
D. It is associated with high alcohol intake

**Core Concept:**

Dupuytren's contracture is a progressive fibromuscular disease affecting the palmar fascia of the hand, leading to the formation of contractures and eventually hand dysfunction. This condition primarily affects elderly males, with a prevalence of around 2-5% in the general population. While it is true that Dupuytren's contracture primarily affects the elderly, it is not considered a rare disease, as its prevalence is relatively high.

**Why the Correct Answer is Right:**

Option B (It is primarily caused by trauma) is incorrect because Dupuytren's contracture is not directly associated with trauma or injury. The disease is believed to have a complex etiology involving genetic, environmental, and possibly hormonal factors. While trauma may exacerbate the disease, it is not the primary cause.

**Why Each Wrong Option is Incorrect:**

Option C (It is a neurological disease) is incorrect because Dupuytren's contracture is a fibromuscular disorder affecting the hand, not a neurological condition. The condition primarily involves the palmar fascia and hand function rather than the nervous system.

Option D (It is associated with high alcohol intake) is incorrect because there is no clear evidence supporting a direct link between alcohol consumption and the development or progression of Dupuytren's contracture. While alcohol may exacerbate symptoms in some cases, it is not a primary risk factor.

**Clinical Pearl:**

Dupuytren's contracture is a complex disease involving multiple factors, including genetic predisposition and possibly hormonal influences. It primarily affects the hand and should be distinguished from neurological diseases and injuries caused by trauma. While alcohol consumption may worsen symptoms, it is not a primary risk factor or cause of the disease.
