摘　　要：目的通过数字化分析、测量青少年骶骨安全骨性螺钉钉道并观察钉道增龄变化的规律。方法收集160名10~17岁健康青少年志愿者骨盆CT扫描数据,三维重建测量S_(1)、S_(2)横向骶髂螺钉最优置钉通道的轴向狭窄处的宽度,测量S_(1)、S_(2)最优钉道经“骶骨经髂骨”(trans-sacral trans-iliac,TSTI)螺钉通道长度,测量S_(1)、S_(2) TSTI通道投影长短轴长度并观察通道随年龄增长的变化规律。结果S_(1)骶髂螺钉安全通道宽度,男性:左(8.96±2.02)mm,右(9.03±2.24)mm;女性:左(8.26±1.96)mm,右(8.37±2.11)mm。S_(1)处TSTI螺钉长度,男性(141.25±5.92)mm,女性(134.37±5.68)mm。S_(2)骶髂螺钉安全通道宽度,男性:左(6.49±1.98)mm,右(6.38±1.88)mm;女性:左(6.21±1.76)mm,右(6.14±1.55)mm。S_(2)处TSTI螺钉长度,男性(126.28±4.94)mm,女性(122.31±5.13)mm。结论青少年在S_(1)、S_(2)均存在影像学上安全的骨性髂骶螺钉通道,随着年龄的增长,通道投影长短轴比例逐渐加大,高度的增长速度快于宽度的增长速度。Objective To explore the rule of the aging change of the screw pathway through digital analysis,measurement of the safety sacral screw pathway of adolescents.Methods The pelvic CT scan data of 160 healthy adolescent volunteers aged 10~17 years old were collected in this research.The width of the axial"narrow point"of the optimal transverse sacroiliac screw placement channel of the S_(1),S_(2) was measured bilaterally by three-dimensional reconstruction.The length of the screw pathway through the"transsacral trans-iliac"(TSTI)at the superior screw pathway,and the width of the long and short axis of the TSTI pathway projection of the S_(1) and S_(2) were measured at the same time,and the changes of the pathway with age were observed.Results S_(1) sacroiliac screw safety pathway width was left(8.96±2.02)mm,right(9.03±2.24)mm in male;left(8.26±1.96)mm,right(8.37±2.11)mm in female.Sacral length of S_(1) TSTI screw was(141.25±5.92)mm in male,(134.37±5.68)mm in female.S_(2) sacroiliac screw safety pathway width was left(6.49±1.98)mm,right(6.38±1.88)mm in male;left(6.21±1.76)mm,right(6.14±1.55)mm in female.Sacral length of S_(2) TSTI screws was(126.28±4.94)mm in male,(122.31±5.13)mm in female.Conclusions There are radiologically safe bony iliosacral screw pathways in both S_(1) and S_(2) in adolescents.With the increasing of age,the ratio of the width of the long and short axis of the TSTI pathway projection of the S_(1) and S_(2) gradually increases,and the growth rate of height is faster than that of width.
