Measurement of femoral neck anteversion with three - dimensional reconstruction 的三維重建技術(shù)測量股骨頸前傾角
Measurement of femoral neck anteversion with three - dimensional reconstruction by spiral - ct 的三維重建技術(shù)測量股骨頸前傾角
Impeller changed from two - piece to one - piece because of the good base of the technology level . a five - axis milling machine is used to manufacture the blades , which are swept back at the impeller outlet and have a trailing edge which is inclined slightly in the axial direction 從分體葉輪到整體葉輪,在工藝水平上已具有較好的基礎(chǔ),前傾后彎葉輪設(shè)計中的較大前傾角通過五軸聯(lián)動銑床實現(xiàn)。
Result : range of motion after total hip arthroplasty depended on design parameters such as head - neck ratio , but also on the implantation parameters such as the cup ' s inclination and antevertion , the stem ' s antevertion and their combination of each other 結(jié)果:全髖關(guān)節(jié)置換術(shù)后的活動范圍不僅取決于假體設(shè)計的某些參數(shù),如頭頸直徑比,還取決于假體安置的某些參數(shù),如臼杯的外展角和前傾角,假體柄的前傾角,以及臼杯和柄的相互方向等等。
