ANSWER
The fractures of the pubes and ischia are obvious. However,
note the accompanying injuries in the posterior portion of
the pelvis, including a fracture of the right side of the
sacrum and a dislocation of the left sacroiliac joint. Anterior
ring pelvic fractures are often associated with companion
fractures of the posterior pelvic ring as in this case. Careful
search should be made for these routinely.
