Article Title: Triangular Screw Placement to Treat Dysmorphic Sacral Fragility Fractures in Osteoporotic Bone Results in an Equivalent Stability to Cement-Augmented Sacroiliac Screws—A Biomechanical Cadaver Study

doi: 10.3390/jcm14051497

Figure Lengend Snippet: ( A ) Schematic drawing of the triangular fixation of the sacrum. Two oblique screws in the S1 vertebra and a transiliosacral screw in the S2 vertebra. ( B ) Schematic drawing of the additional cement augmentation of the oblique screws in the S1 vertebra. Dotted red line represents the fracture-lines.

Article Snippet: Group 1: In this group, we stabilized the sacral fracture using two partially threaded sacroiliac screws from both sides, oblique inverted (cannulated, partial threaded steel screw 7.3 mm, DePuy Synthes, Raynham, MA, USA), and a fully threaded transiliosacral screw (cannulated, fully threaded steel screw 7.3 mm, DePuy Synthes, Raynham, MA, USA), which led to a total of 6 cortical index osteosynthesis procedures of groups 1 and 2 together ( A).
