  • 內容： The orientation of the hip joint cup is one of the most important prognostic factors in total hip Arthroplasty. It consists of two parameters: the abduction (inclination) and anteversion angles. Anteversion can be further subdivided into true(antomic) and planar(radiographic) anteversion and Operative anteversion (flexion). We developed a new protractor to measure the orientation of the cup in total hip arthroplasty. With this new device, we can easily measure the true and planar anteversion as well as abduction. No other instruments such as a calculator or special table are needed, but a good quality antero-posterior roentgenogram is required.
