**Question:** Pat's fracture is fracture of
A. Radius
B. Ulna
C. Colles' Fracture
D. Greenstick Fracture
**Correct Answer:** C. Colles' Fracture
**Core Concept:** Colles' Fracture is a specific type of distal radius fracture that occurs predominantly in elderly patients, especially in women, and is typically associated with a fall on an outstretched hand. The fracture occurs at the distal end of the radius, often with rotation and angulation of the forearm.
**Why the Correct Answer is Right:** Colles' Fracture is named after Sir James Colles, who first described the fracture in 1814. It is characterized by a fracture of the distal radius, which results in instability of the radiocarpal joint. This type of fracture is often associated with a fall on an outstretched hand, causing the forearm to be internally rotated and angulated.
**Why Each Wrong Option is Incorrect:**
A. Radius (Option A) - Colles' Fracture is a specific type of fracture involving the distal radius, not the entire radius.
B. Ulna (Option B) - Colles' Fracture specifically involves the distal radius, not the ulna.
D. Greenstick Fracture (Option D) - Colles' Fracture is not a type of greenstick fracture, which is a bending fracture that occurs in children due to the relatively flexible bones.
**Why Each Wrong Option is Incorrect:**
A. Radius (Option A) - Colles' Fracture involves the distal radius, not the entire radius.
B. Ulna (Option B) - Colles' Fracture specifically involves the distal radius, not the ulna.
D. Greenstick Fracture (Option D) - Colles' Fracture is not a type of greenstick fracture, which is a bending fracture that occurs in children due to the relatively flexible bones.
**Clinical Pearl:** Colles' Fracture is an important entity to recognize due to its specific mechanism of injury and characteristic presentation. Early recognition and management are crucial to prevent malunion, deformity, and loss of function. Treatment typically involves immobilization with a cast or splint for a period of at least 6-8 weeks to allow for proper healing and alignment of the radiocarpal joint.
