Eligibility
Sex/Gender
All
Age
18 Years to 100 Years
Inclusion criteria
Inclusion criteria: - procedures with iliosacral and/or transsacral screw insertions AND - intraoperative 3D-fluoroscopy scan with the O-arm for navigational data acquisition AND - 3D-image guided screw insertion using the S7 StealthStation navigation unit AND - visual control of final screw positions by 3D-fluoroscopy with the O-arm
Exclusion criteria
Exclusion criteria: - iliosacral/transsacral screw insertion without the use of 3D-image guidance OR - use of pre-surgical CT scans for image-guided iliosacral/transsacral screw insertions OR - omitting a final 3D-fluoroscopy scan with the O-arm for screw position control
Design outcomes
