摘要
Abstract
Objective:To explore the feasibility of the second sacral vertebrae(S2)pedicle screw fixation and provide anatomical basis for its placement.Methods:Adult cadaveric lumbosacral specimens were selected,and parameters including screw trajectory length and lateral angulation angle were measured.Results:The lateral trajectory length was(26.87±4.28)mm,with a lateral angulation angle of(29.26±7.87)°;the medial trajectory length was(34.69±5.60)mm,with a lateral angulation angle of(44.81±4.74)°.Conclusion:S2 pedicle screw fixation is feasible with an appropriate lateral angulation angle.关键词
