Before studying distal radius fracture, it is necessary to know what’s difference between extra articular fracture and intra articular fracture?
Extra articular fracture v/s intra articular fracture :
1. Extra articular fracture –
Articular surface (Joint) not involve (see blue line on radius bone)
eg. Colle’s fracture and smith fracture.
2. Intra articular fracture –
Articular surface (Joint) involve (See black line on radius bone)
eg. Barton’s fracture and Chauffeur fracture.
Distal Radius Fracture :
1. Colle’s fracture –
a. Extra articular fracture
b. Fracture at cortico cancellus junction of radius bone.
c. Broken part the radius bone displaces dorsally (Wrist Extension)
2. Smith fracture –
a. Extra articular fracture
b. Fracture at cortico cancellus junction of radius bone.
c. Broken part the radius bone displaces ventrally (Wrist flexion)
3. Barton’s fracture –
It is the intra articular fracture of distal radius bone.
4. Chauffeur’s fracture –
a. Intra articular fracture
b. Fracture of radius styloid process.
