AO/OTA Classification of Distal Humeral Fractures
< AO
Overview[1][2]
The injuries of the ball-and-socket shoulder joint considered as the Distal humerus fracture. It is more common among the elderly population following a low energy trauma such as falling. Meanwhile, A few people experience the axillary nerve damage such as reduced sensation around the middle deltoid and/or axillary artery involvement.
AO/OTA Classification of Distal Humeral Fractures
The distal humerus fracture may be classified based on the exact location of fracture:
- Distal third of humerus
- Intercodylar (Intra articular)
- Supracondylar (High and low supracondylar; flexion and extension)
AO/OTA Classification of Distal Humeral Fractures | ||
---|---|---|
Type A | Extra-articular | |
Type B | Intraarticular- Single Column | |
Type C | Intraarticular- Both Columns |
