The T-Shaped Fractures of the Acetabulum

The T-shaped pelvic fracture represents from 3%-12% 1 of all acetabulum fractures. It is defined as a transverse acetabulum fracture in combination with a vertical fracture that divides the posterior column from the anterior column (Figure 1). Although the T-type fracture affects both columns, it differs by definition from a fracture of both columns in that part of the acetabulum articular surface still remains stably attached to the iliac pelvic ring.
