Background Anterior sacroiliac joint plate fixation for unstable pelvic ring fractures avoids soft tissue problems in the buttocks; however, the lumbosacral nerves lie in close proximity to the sacroiliac joint and may be injured during the procedure. Methods A 49 year‐old woman with a type C pelvic ring fracture was treated with an anterior sacroiliac plate using a computed tomography (CT)–three‐dimensional (3D)‐fluoroscopy matching navigation system, which visualized the lumbosacral nerves as well as the iliac and sacral bones. We used a flat panel detector 3D C‐arm, which made it possible to superimpose our preoperative CT‐based plan on the intra‐operative 3D‐fluoroscopic images. Results No postoperative complications were noted. Conclusions Intra‐operative lumbosacral nerve visualization using computer navigation was useful to recognize the 'at‐risk' area for nerve injury during anterior sacroiliac plate fixation.
