Transverse fracture of the upper sacrum. Suicidal jumper's fracture.

Thirteen patients with transverse fractures of the upper sacrum were studied to determine fracture anatomy, clinical presentation, and therapeutic approaches. The injury results from falls from a height and is usually associated with suicidal attempts by jumping. The position of the lumbar spine in lordosis or kyphosis at the time of impact determines which of three types of morbid anatomy will result. Because of associated polytrauma, fracture of the upper sacrum is often not recognized in the acute stage, and awareness of the possibility of such injury, especially in the presence of perineal neurologic deficit should result in securing good quality radiographic study, including tomograms. Surgical treatment is often required.
