Overview[1][2][3]
The injuries of the ball-and-socket shoulder joint considered as the Humeral shaft 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.
Müller AO Classification of the Humeral shaft fracture
The Humeral shaft fracture can be classified AS:
- Anatomical location: proximal, middle or distal third
- Fracture pattern: spiral, short oblique, transverse or comminuted
- Degree of displacement
- Presence of soft tissue damage (open or closed)
Meanwhile, the Müller AO Classification is a well known classifying system for the fractured bone published in 1987.
Type | Group | ||
---|---|---|---|
1 | 2 | 3 | |
A - Simple fractures | Spiral | Oblique ≥30º | Transverse < 30º |
B - Wedge fractures | Spiral wedge | Bending wedge | fragmentory wedge |
C - Multifragmentary fractures | intact segmental | fragmentary segmental |
