Transverse fractures of the sacrum. A report of six cases.

The diagnosis of transverse sacral fracture was made in six patients. All patients initially had evidence of urinary retention, a decrease in anal sphincter tone, or both. Diagnostic confirmation was established by tomography in four patients and by cystometric examination in two. All patients who had transverse sacral fractures with displacement of the fragments had resolution of their neurological deficit following posterior sacral laminectomy and decompression.
