Outcome of Screw Fixation for Crescent Fractures

1:56 PM - 2:02 PM PST
Location: 608-609
Purpose: Our objective was to clarify the outcomes of screw fixation for crescent fracture.

Methods: The setting was a single trauma center. 18 cases of pelvic ring fracture including crescent fracture were selected from 146 cases of pelvic fractures surgically treated at the center from April 2021 to December 2022. There were 5 males and 13 females, with a mean age of 68 years. 8 were type 1, 3 were type 2, and 7 were type 3 according to the Day classification. The exposure was percutaneous or open reduction and screw fixation regardless of the size of the crescent fracture. Primary outcome was bone union and reduction loss; secondary outcomes were operative time, intraoperative blood loss, perioperative complications, and implant loosening.

Results: All the fractures achieved bone union without reduction loss. The mean operative time was 114 minutes (range, 61-188 min), and mean blood loss was 152 mL (10-959 mL). One case revealed an S1 nerve root injury due to the incorrect insertion of a transiliac-transsacral (TITS) screw, which required reoperation.

Conclusion: All types of crescent fractures can be treated with screw fixations.
