The term, sacral fracture with traumatic spino-pelvic dissociation, is applied to those fractures of the sacrum in which there are both transverse and sagittal fracture lines in the sacrum, leading to a mechanical dissociation of the spine and the proximal fragment of the sacrum from the remaining sacrum and the pelvis.
It is a quite rare pathological condition, and probably underdiagnosed. As it usually results from a high energy multiple trauma, an early diagnosis and treatment are mandatory for a better functional prognosis.
We present a literature review of this relatively unknown injury.
