Abstract
Purpose
The purpose of this study is to evaluate preliminary outcomes of vertically unstable sacral fractures treated by lumbopelvic fixation (LPF) augmented transiliac bridged screws.
Methods
From April 2017 to December 2019, fifteen consecutive patients with vertically unstable sacral fractures who had undergone LPF augmented transiliac bridged screws were enrolled. The radiological assessment included standard lumbopelvic x-rays and pelvic computed tomography (CT) to evaluate the lumbosacral angle (LSA), sacral kyphosis angle (SKA), lumbar lordosis angles (LLA) and Matta’s reduction criterias (MRC). Clinical and neurologic impairment outcomes were evaluated by the Majeed grading scale (MGS) and Gibbons criterias, respectively.
Results
All patients were followed for an average of 18 months (range, 14–25). All sacral fractures eventually healed and implant failure did not occur in any patient, though there were two patients with a loss of reduction (< 5 mm) during the follow-up period. According to the MRC, the results were excellent on 14 sides, good on five sides, and fair on one side. The MGS mean score was 82 points (range, 49–98 points); the results were excellent in nine cases, good in four cases, and fair in two cases. There was no statistically significant difference in SKA and LLA in preoperative and postoperative final controls. The preoperative and postoperative LSA were 72 ± 13.9 and 44.1 ± 11.3, respectively, and a statistically significant improvement was observed (p = 0.01).
Conclusion
In vertically unstable sacrum fractures, we believe that LPF augmented with transiliac bridging technique may expedite the reduction of vertical sacrum fracture and offers a reinforced fixation choice.
