Percutaneous screw fixation for pelvic fractures with fluoroscopy-based navigation / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the applications of fluoroscopy-based navigation in pelvic fractures and related surgical considerations.</p><p><b>METHODS</b>From May 2010 to December, 16 patients with pelvic fractures were treated with computerized navigation. There were 12 males and 4 females with an average age of 37 years (ranged from 20 to 54 years). Fractures were caused by traffic accident in 5 cases, crush injury in 5 cases and falling from height in 6 cases. Based on the Tile classification, there were 15 cases of Tile C type and 1 case of Tile B type. In these patients, 4 patients were treated with sacroiliac screw fixation; 2 patients were treated with sacroiliac screw fixation, screw fixation for pubic symphysis diastasis and pubic fractures; 8 patients were treated with sacroiliac screw fixation and screw fixation for pubic fractures; 2 patients were treated with screw fixation for pubic fractures. The index such as screw inserting time, accurance of inserting screws, intra-operative blood losing, injuries of nerve, vascular and other organs, reduction conditions were observed.</p><p><b>RESULTS</b>A total of 36 screws were inserted. The average time was 20 min for each screw placement. The blood loss ranged from 10 to 20 ml. There were no wound infections, neurovascualr injuries and other organ injuries. The postoperative pelvic X-ray and three-dimensional CT showed that the fractures had good reduction and all the screws had good position.</p><p><b>CONCLUSION</b>Percutaneous screw fixation of pelvic fractures with fluoroscopy-based navigation have advantages such as little trauma, less blood loss, little complication, reliable fixation and no blood transfusion, which can reconstruct the stability of the pelvic ring, but need adequate preoperative reperation and high requirements for the surgeon.</p>
