posterior superior iliac spine

The inferior gluteal nerve penetrated from the pelvis mainly in the middle 1 / 3 ( 50 . 00 % ) of the line from the posterior superior iliac spine to the ischial tuberosity or at the junction of its superior-middle 1 / 3 ( 48.33 % ) .

其穿出点的位置主要在髂后上棘与坐骨结节连线的中1/3（50.00%）或上、中1/3交界处（48.33%）。

The widths and height of the projection , and the distances from the axis of the projection to posterior superior iliac spine and posterior inferior iliac spine were measured bilaterally .

分别测量两侧投影的宽度、高度、投影纵轴到髂后上棘、髂后下棘的距离。

The vertical distance from the sacral nerve emerged above and below the piriformis muscle to the PS line connecting the posterior superior iliac spine and the sacral horn line was measured .

以髂后上棘至同侧的骶角连线（PS线）为基线，测量各神经出梨状肌上、下缘处至PS线的垂直距离。

The average distances from the line which connected the posterior superior iliac spine and posterior inferior iliac spine to the posterior and anterior lateral lines were 3.47 cm and 5.66 cm , respectively .

髂后上下棘连线距矩形后侧边和前侧边的距离分别为3.47cm和5.66cm。

The patients received prone position local anesthesia , and then treated with multiple point puncture at posterior superior iliac spine . 60-260 mL blood was extracted from bone marrow . Above-mentioned trail was performed within 60 minutes .

患者俯卧位局麻，双测髂后上嵴行多点穿刺，抽取骨髓血60～260mL，要求在60min内完成。

Methods Thirty patients with spinal osteoarthritis were selected . A metal label with a diameter of 10 mm was fixed on the posterior superior iliac spine according to the landmark of body surface of each patient , then CT scanning was made and observed .

方法选择30例血清阴性脊柱关节病病人，于其体表标志髂后上棘处固定一直径为10mm圆形金属标记物，行骶骼关节CT扫描并观察。
