Forensic Medicine · Injuries and wounds: parry fracture

Sample item

A man raised his forearm to protect his head from a lathi blow and has an isolated transverse fracture of the mid-shaft of the ulna. What is this injury commonly called, and what does it suggest?

AA Galeazzi fracture, from a direct hit to the radiusBA Colles fracture, from a fall on the outstretched handCA nightstick (parry) fracture, suggesting a defensive postureDA Monteggia fracture, from a fall on the elbow

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. A nightstick (parry) fracture, suggesting a defensive posture

A solitary ulnar shaft fracture from a direct blow to the raised forearm is called a nightstick or parry fracture and is a classic defensive injury. Monteggia involves ulnar fracture with radial head dislocation and Galeazzi radial shaft fracture with distal radioulnar dislocation.

Option by option

A. A Galeazzi fracture, from a direct hit to the radius
A Galeazzi fracture involves the radius with distal radioulnar joint dislocation.
B. A Colles fracture, from a fall on the outstretched hand
A Colles fracture is a distal radius fracture from a fall on the hand.
C. A nightstick (parry) fracture, suggesting a defensive posture (correct)
Correct. An isolated ulnar shaft fracture from a blow to the guarding arm is a parry fracture.
D. A Monteggia fracture, from a fall on the elbow
A Monteggia fracture includes dislocation of the radial head, not an isolated ulnar break.
