Advances in fixation strength of reorienting rectangular triple pelvic innominate osteotomies – A biomechanical investigation of two screw fixation techniques

Bidirectional screw alignment does not lead to significant advantages compared to pure monoaxial if all three axial screws are evenly distributed over the osteotomy geometry. The triple pelvis innominate osteotomy is susceptible to changes in anteversion and inclination under partial weight bearing. Cautious rehabilitation protocols are recommended.
