Colles Fracture (Dinner fork deformity)

This frx was described by Abraham Colles in 1814, originally described as low energy extra articular frx of distal radius occuring in elderly individuals;
- frx is typically dorsally displaced and angulated;
- mechanism:
- fracture is also caused by a forced dorsiflexion of the wrist;
- occurs in pts > 50 years of age who fall on out stretched hand;
- dorsal surface undergoes compression while volar surface undergoes tension;
