Clinical examination

The patient should be evaluated for:

• Age
• Hand dominance
• Occupation
• Level of activity
• Quality of bone
• General medical condition


 

Complete articular fracture of the radius, articular simple, metaphyseal multifragmentary 

These are complete articular fractures of the radius, with a simple articular fracture and a multifragmentary metaphyseal component.

These are classified by AO/OTA as 2R3C2.

There may be an associated ulnar injury. This is usually a fracture of the ulnar styloid process, but other ulnar fractures are possible.
The articular components of these fractures usually comprise a single fracture line into the joint.

 

When there is a sagittal split of the articular surface between the scaphoid and lunate facet, this is classified by AO/OTA as 2R3C2.1.

When the articular surface is split in a coronal plane, this is classified by AO/OTA as 2R3C2.2.
This fragment can form the dorsal part of both the lunate fossa and the sigmoid notch. Reduction of this fragment by closed methods is very difficult, because of the transverse orientation of the extrinsic dorsal radiocarpal ligaments.

 

When there is additional extensive metaphyseal comminution, this is classified by AO/OTA as 2R3C2.3.
