Proximal Humerus Fracture Classification

Type A1 proximal humerus fracture

 A1 Extra-articular unifocal fracture, tuberosity

  • For subdivision see AO Classification.
  • A1.1=greater tuberosity fx, Nondisplaced (<5mm displacement): Sling, start PT within 2 wks for passive ROM only.  Start strengthening, active ROM after fracture union is evident.
  • A1.2=greater tuberosity fx Displaced (displaced >5mm): CRPP vs ORIF (Flatow JBJS 73A 73:1213;1991).
  • A1.3=with GH dislocation: GH joint should be reduced ASAP. Greater tuberosity fractures are then treated based on the amount of displacement seen on post-reduction xrays.
  • See also Greater Tuberosity fracture.

 

Type A2 proximal humerus fracture

A2 Extra-articular unifocal fracture, impacted metaphyseal

  • For subdivision see AO Classification.
  • <66% translation: sling, start PT within 2 wks for passive ROM only.  Start strengthening, active ROM after fracture union is evident.
  • >66% translation: CRPP vs ORIF
Type A3 proximal humerus fracture

A3 Extra-articular unifocal fracture, non-impacted metaphyseal

  • For subdivision see AO Classification.
  • <66% translation: sling, start PT within 2 wks for passive ROM only.  Start strengthening, active ROM after fracture union is evident.
  • >66% translation:CRPP vs ORIF
Type B1 proximal humerus fracture

B1 Extra-articular bifocal fracture, with metaphyseal impaction

Type B2 proximal humerus fracture

B2 Extra-articular Bifocal fracture, without metaphyseal impaction

Type B3 proximal humerus fracture

B3 Extra-articular bifocal fracture, with GH dislocation

Type C1 proximal humerus fracture

C1 Articular fracture, with slight displacement

Type C2 proximal humerus fracture

C2 Articular fracture, impacted with marked displacement

Type C3 proximal humerus fracture

C3 Articular fracture, with GH dislocation
