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
Type	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
