AO extra no displacement
2R3A2.1
no operation
AO extra dorsal tilt, Colles
2R3A2.2
AO extra volar, Smith
2R3A2.3
AO extra articular wedge
2R3A3
extra simple wedge 2R3A3.1
extra fragm wedge 2R3A3.2
extra multifragm wedge 2R3A3.3
AO partial sagital
2R3B1
partial scaphoid fossa (Chauffeur) 2R3B1.1
No B1.2 !!! Page 31
partial lunate 2R3B1.3
- OP yes/no by B1.3 depends on degree of displacement
AO partial classic (dorsal) Barton rim
2R3B2
partial dorsal, Barton, simple 2R3B2.1
partial dorsal, Barton, fragmentary 2R3B2.2
Barton dislocation 2R3B2.3
Volar ligament often detached
if needed re-attach with ankers +/- fix ex
AO partial reverse (volar) Barton, volar rim
2R3B3
reverse (volar) Barton simple 2R3B3.1
No B3.2 !!
reverse (volar) Barton multi 2R3B3.3
Dorsal ligaments often detached
Palmar plate
Normal radial length
10-13 mm most determining prognostic factor after ORIF
Normal radial inclination
21-25°
Normal radial tilt
11° (2-20°)
Strict lateral
palmar corticalis of Pisiform must be midway (ok if between) palmar corticalis of Capitatum and Scaphoid
Indication for operation : High Demand
Ulna+ > 2 mm
Articular step >1 mm
Fracture gap >1 mm
Dorsal til >10°
Indication for operation : Low Demand
Ulna+ >4mm
Articular step >2 mm
Fracture gap >2 mm
Dorsal til >20°
Instability criterias (indication if >1) for A Fractures
Dorsal or palmat multifragmentary zone
Break of palmar or dorsal rim
Basal psu fracture
Redislocation after reposition
