98. EARLY EXPERIENCE WITH REDUCTION OF DISPLACED PELVIC RING DISRUPTIONS USING A PELVIC REDUCTION FRAME

Abstract

Purpose: To describe operative experience and reductions of pelvic ring fractures treated with a novel pelvic reduction frame.

Method: All patients with displaced pelvic ring disruptions treated with the pelvic reduction frame were included. The series includes 35 patients, with 34 acute fractures and one malunion. Pre-operative and immediate post-operative radiographs were reviewed, and maximal displacement measured using two reproducible methods. Procedure and injury data were also recorded.

Results: In our series of 35 patients, we had 19 vertical shear fractures and 16 compression injuries. Mean age was 33.5 + 2.4, and mean delay to surgery was 4.7 + 0.6 days. Mean operative time in isolated procedures was 103.4 + 6.5 minutes. All but one patient had iliosacral screws placed, 18 had anterior column screws, six had symphysis plates and 12 had anterior external fixators. Maximum horizontal or vertical displacement was improved from 30.8 + 2.7 mm to 7.1 + 0.7 mm. Diameter asymmetry as measured on the AP view was improved form 26.4 + 2.7 mm to 5.2 + 0.7 mm. Very good, good or fair reduction was obtained in all acute cases. There was no statistically significant impact of obesity, fracture type or delay to surgery on quality of reduction (p> 0.05).

Conclusion: This novel pelvic reduction frame is a powerful tool in the effective reduction and fixation of displaced acute pelvic ring disruptions.
