Question

A Colles' fracture usually involves which of the following?

2) Posterior and outward displacement of the hand
3) Chip fracture of the ulnar styloid process
a. 1 only
b. 1 and 2 only
c. 2 and 3 only
d. 1, 2, and 3

Answer 1

A Colles' fracture involves a transverse fracture of the distal radius, posterior and outward displacement of the hand, and possibly a chip fracture of the ulnar styloid process.

Step-by-step explanation:

A Colles' fracture usually involves the following: a complete transverse fracture across the distal radius, along with posterior and superior displacement of the separated distal fragment of the radius.

This type of fracture often results in a ‘dinner fork’ deformity due to the posterior displacement of the hand. In some cases, it may also include a chip fracture of the ulnar styloid process.
