Mechanisms of Injury to the Pelvic Ring

Injury patterns correlate with the vector of the provocative blow. The force vectors and pelvic injury patterns also correlate with the anticipated patterns of additional injuries to the abdomen, intrapelvic contents, chest, and head, as well as with the potential for significant hemorrhage.

A anteroposterior (AP) pelvic radiograph, therefore, provides insight into the force vector and the likelihood for co-injuries for which appropriate diagnostic tests can be initiated promptly.

Principal pelvic fracture patterns based on the vector of the provocative force

Anteroposterior: Anteroposterior compression/external rotation injury
Lateral: Lateral compression/internal rotation injury
Vertical: Vertical shear fracture
