Transverse fracture-dislocations of the sacrum are rare. Associated lesions of the lumbosacral spine as well as neurological injuries are common. Conventional radiographs of the pelvis often fail to clearly visualize the fracture. ⋯ Both lesions in this patient were successfully stabilized using an internal fixator system. The other patient presented with a bilateral transforaminal sacral fracture. The transverse component was not recognized on the initial radiographs, which resulted in loss of reduction and progressive neurological disfunction after sacroiliac screw fixation.
