摘要：

Acetabular CLIP orientation is a key factor determining hip stability, and standard mechanical guides have shown little help in improving alignment. An in vitro study was carried Out to compare the accuracy and precision of a new gravity-assisted guidance system with a standard mechanical guide. Three hundred ten cups were impacted by 5 Surgeons, and the final CLIP orientation was measured. With the new guide, the average error in anteversion was 0.4 degrees, compared with 10.4 degrees with the standard guide and 0.3 degrees and -4.7 degrees, respectively, for abduction angles. The average time required for orienting the cups was similar for both guides. The accuracy and reproducibility obtained with the new guide were better ( P < .0001). These good results would require a clinical validation.
