Traumatic pelvic and sacral fractures

Case contributed by Dr James Sheldon

Presentation

Pedestrian hit by motor vehicle.

Patient Data

Age: 40 years
Gender: Male
Modality: CT

There is diastasis of the pubic symphysis, with the left pubis superiorly displaced and overriding the right pubis. There are comminuted fractures through both sacral ala with elevation of the lateral fragment of the left sacrum and a fracture of the left L5 transverse process. The fractures involve the sacral foraminae bilaterally, and there is also extension into both sacroiliac joints. No associated SI joint dislocation.

These fractures are suggestive of vertical shear mechanism of injury.

There is an associated moderate sized extraperitoneal pelvic haematoma within the left hemi-pelvis with extension of haematoma into the posterior pararenal space of the left retroperitoneum. There is also intramuscular and subcutaneous haematoma within the left groin, and haematoma within the left lower abdominal wall.
