Three-dimensional navigation-guided percutaneous screw fixation for nondisplaced and displaced pelvi-acetabular fractures in a major trauma centre.

Background: Navigation assisted minimally invasive percutaneous screw fixation (MIS) for pelvi-acetabular fracture was recently advocated.

Methods: We report 38 consecutive cases of pelvi-acetabular fractures treated with 3D navigation-guided MIS from 2015 to 2016. Ohe hundred and forty-three screws were inserted (59 sacroiliac, 45 retrograde anterior column, 34 supra-acetabular, three antegrade posterior-column and two subcristal).
