“…In the present study, the accuracy of cup placement was significantly improved by using the image-free navigation system in patients with primary osteoarthritis of the hip, and angulations outside the safe zone were largely avoided. The clinical results of imagefree navigation for cup inclination and anteversion ranges and standard deviations were comparable to anatomical studies of image-free navigation and also with clinical studies of CT-based and fluoroscopy-assisted navigation methods [9,12,16,19,20]. In contrast to the image-assisted CT-based or fluoroscopy-based navigation methods, however, image-free navigation requires neither pre-operative nor intra-operative imaging.…”

“…Die Werte für Inklination und Anteversion der Hüftpfannen, für die Spanne und die Standardabweichungen entsprechen bereits publizierten Studien zu CT-basierten und fluoroskopie-gestützten Verfahren [1,12,19,20]. Mit dem intraoperativen Vergleich der bildfreien zur CT-basierten Software konnte aufgezeigt werden, dass zwischen beiden Systemen lediglich eine mediane Abweichung von -1,5°(Spanne -7 -0°) bei der Inklination und von -0,5°(Spanne -4 -4°) bei der Anteversion vorliegt.…”

“…Numerous reports suggest the ranges of accuracy with which implants can be placed using computer-assisted surgical navigation typically will have standard deviations of 1°to 10°from the control [5,17,19,23,30,31,43,44,48]. We believe the primary objective of computer-assisted surgery (CAS) is to eliminate unacceptable outliers and we discuss limitations of these prior studies.…”
