Two compression rods to treat unstable lesions of the pelvic ring.

The authors report 7 cases involving the surgical treatment of unstable pelvic ring fractures (Malgaigne type) using two compression bars, as described by Tile. The method was used only in cases where x-ray examination and CT scan revealed that the posterior branch of the fracture was located at the very medial aspect of the sacrum (fracture through the sacral foramina or even medial to the sacral foramina), and therefore could not be stabilized by using other devices.
