Complex Pelvic Fractures

An anterior compression force results in disruption of the SI joints (>4mm), diastasis of the symphysis pubis (>5mm) and external rotation of the hemipelvis. Also known as an "open book" injury:

Anterior compression   Anterior compression
Anterior compression - inlet projection   Anterior compression - outlet projection

A lateral compression force results in oblique fractures of the pubic rami bilaterally (with overlapping fragments), impacted fractures of the sacral foramina ipsilateral to the force, with infolding of the hemipelvis:

Lateral compression   Lateral compression

A vertical shearing injury results in vertical, unilateral fractures of the pubic rami, vertical fracture of the sacral foramina on the same side (or fractured ileum paralleling SI joint/disruption of the SI joint) with the hemipelvis usually displaced superiorly:

Vertical shearing   Vertical shearing

A straddle injury refers to a force against the perineum. This results in fractures of all pubic rami bilaterally with the central fragment displaced superiorly.
