Abstract:
Isolated horizontal sacral fractures that do not influence pelvic ring stability are rare. Several techniques to stabilize these fractures have been described. This technical note describes a technique of retrograde screw fixation in a 75-year-old female with severe osteoporosis and large Tarlov cysts in the sacrum. It is a minimally invasive, navigation assisted technique that allowed to reduce the fracture and stabilize it adequately.
