The proper level of transection of the femoral neck for hip arthroplasty can be ascertained by using the proximal tip of the intact greater trochanter as a reference point. A transverse line projected medially from this point will cross the true level of the center of rotation of the femoral head for that hip. Placement of a trial prosthesis in accordance with this level will locate the point at which the femoral neck should be cut. By placing the femoral component so that its center of rotation is bisected by the same line, the level of the calcar flange can be marked on the neck of the femur. This is the level at which the femoral neck should be cut.
髋关节置换术中股骨颈的合适截骨水平可通过将完整大转子的近端尖端作为参考点来确定。从该点向内侧投射的一条横线将穿过该髋关节股骨头旋转中心的真实水平。按照此水平放置试验假体将确定股骨颈应被截断的位置。通过放置股骨部件，使其旋转中心被同一条线平分，可以在股骨颈上标记出股骨距凸缘的水平。这就是股骨颈应被截断的水平。
