To the femoral neck fracture with neck-shaft angle of less than 135 degree, the fixation with the entry angle of less than 135° can make the neck-shaft angle rising, meanwhile, lag screw's location is easier to trend to the inferior of femoral head, displacement and angle between fracture surfaces satisfy the demand of functional reduction or extroversion reduction, and a satisfied stability is performed in biomechanical test.

对于颈干角小于135°的股骨颈骨折，以低于135 °的进钉角度固定时，能增大颈干角，同时拉力螺钉的位置更容易偏向股骨头颈的中、下部，骨折端的位移、成角也能够符合功能复位的要求，在力学测试中表现出较好的稳定性。

Parker's ratio decreased when the entry angle decreased, lag screw's location trended to the inferior of the femoral head.

随着进钉角度的减小，正位像上的Garden指数从160°增加到172°，Parker比率逐渐减小，拉力螺钉位置趋向于股骨头的下方。
