Anatomical evaluation of the transpubic screw corridor based on a 3D statistical model of the pelvic ring

Abstract Retrograde transpubic screw fixation is a common procedure for the treatment of anterior pelvic ring fractures. With its sparing surgical approach and significant pain relief after screw fixations allowing early mobilisation, it has gained importance especially in the treatment of insuffici...
