摘要

Introduction: This prospective random study aims to provide an answer to the following questions: Is the accuracy of computer-assisted acetabular cup placement, both in the case of CT-based and imageless navigation, significantly better than that offered by the conventional operation technique? Is the accuracy of acetabular cup placement using imageless navigation comparable with that of CT-based navigation, or are significant differences evident? Does the use of computer-assisted navigation significantly reduce incorrect cup placement out of the Lewinnek safe zone? Methods: 90 patients were assigned randomly by lot to one of the three study groups: 1) Conventional freehand hip arthoplasty (n=30); 2) CT-based navigated acetabular cup placement (n=30); 3) Imageless navigated cup placement (n=30). The target acetabular cup position for all patients was 45?inclination and 15?anteversion. Depending on the primary stability, however, deviations within the safe zone defined by Lewinnek et al. (1978) (inclination 40?-10?and anteversion 15?-10? were tolerated. In all patients total hip arthroplasty was indicated, because of primary osteoarthritis of the hip. Exclusion criteria were: Dysplatic coxarthrosis, post-traumatic deformities of the pelvis or less than 50 years old, since as preoperative and/or post-operative pelvis CT scans were required for study purposes.
