ObjectiveTo investigate the clinical application of fluoro-navigation in the surgery for pelvic fractures.MethodsA fluoro-navigation system was used to guide the placement of screws for the fixation of pelvic and acetabular fractures in 22 patients, 14 males and 8 females, aged 39.4. Totally 41 screws were inserted, 15 in pubic ramus, 13 in acetabulums, and 13 in sacroiliac joints. The images of fluoro-navigation were compared with those of the real X rays during and after surgery.ResultsThe average time for operation was 22.7 minutes/screw, and the average time of X rays exposure was 20.2 seconds/screw. The mean deviated distance was 2.9 +/- 1.2 mm and the mean deviated angle was (2.2 +/- 0.3) degrees in the post operational verification. The blood loss during the operation was minimal (< 21.7 ml/screw). One screw (2.4%) was deviated out of the fracture during the operation. No complication was recorded after surgery.ConclusionFluoro-navigation-assisted operation for the pelvic and acetabular fracture makes the surgery more precise, safer, and time-saving with less X-ray exposure.
