The 3D image enhancer-adjusted percutaneous triangular stabilization of geriatric pelvic ring fractures avoids implant-associated perioperative complications. Displaced fractures of the posterior pelvic ring require stable instrumentation to enable solid bony fusion in a balanced alignment and to control the risk of neurological and vascular damage. This is mandatory in high-energy injuries in young patients and especially in low-energy injuries of geriatric patients. ⋯ After percutaneous insertion of the guide wires into the L4 vertebral body, the iliac bone and transiliosacrally under 2D X‑ray control, the correct wire position is verified by the 3D scan. Then, screws are inserted and the instrumentation is completed in a standard fashion. Using this technique implant-associated perioperative complications, such as nerve and vascular damage due to screw misplacement can be reduced.
