Displaced transverse fracture of the sacrum with nerve root injury: report of a case with successful operative management.

A displaced transverse fracture of the sacrum occurred in a young woman along with lumbar transverse process fractures, displacement suggesting instability in flexion, and nerve root injury, all features common to this injury. Open decompression, reduction, and Harrington rod fixation were successful for this patient, but the method is not recommended for all sacral fractures.
