Classification of Tile from 1988 for Pelvic Fractures

Rotational Stability	Vertical Stability	Type
stable	stable	A
unstable	stable	B
unstable	unstable	C

 

Type A:

(A1): fractures of the pelvis not involving the ring (avulsion of the anterior iliac spines, anterior inferior iliac spines, ischial tuberosity)

(A2): non or minimally displaced fractures of the pelvic ring

 

Type B: open book or lateral compression

(B1): "open book" (through symphysis pubis)

(B2): ipsilateral (fracture through pubic rami and impaction of posterior joint, same side)

(B3): contralateral "bucket handle"

 

Type C: vertical shear with the posterior lesion involving ligamentous disruption, fracture of the ilium, or fracture of the sacrum (involving the pelvic ring)

(C1): unilateral

(C2): bilateral

(C3): associated with acetabular fracture

 

Tile recommended external fixation for pelvic fractures of Types B or C.
