The study aimed to explore an extra-articular screw placement strategy in Stoppa approach. Radiographic data of patients who underwent pelvic computed tomography from January 2016 to June 2017 were imported into Materiaise's interactive medical image control system software for three-dimensional reconstruction. Superior and lower margins of acetabulum and ipsilateral pelvic brim could be observed simultaneously through inlet-obturator view. A horizontal line from superior acetabular margin intersected pelvic brim at point "A" and another vertical line from lower margin intersected pelvic brim at point "B" were drawn, respectively. Lengths form sacroiliac joint to "A" (a), "A" to "B" (b), and "B" to pubic symphysis (c) were measured. Patients were divided into four groups depending on gender and side difference of measured hemi-pelvis: male left, male right, female left, and female right. Lengths of adjacent holes (d) and spanning different holes (e) of different plates were also measured. Mean lengths of a, b, c in four groups were 40.94 ± 1.85 mm, 40.09 ± 1.93 mm, 41.78 ± 3.62 mm, and 39.77 ± 2.23 mm (P = 0.078); 40.65 ± 1.58 mm, 41.48 ± 1.64 mm, 40.40 ± 1.96 mm, and 40.66 ± 1.70 mm (P = 0.265); 57.03 ± 3.41 mm, 57.51 ± 3.71 mm, 57.84 ± 4.40 mm, and 59.84 ± 4.35 mm (P = 0.165), respectively. Mean d length of different plates was 12.23 mm. Average lengths spanning 1, 2, 3 and 4 holes were 19.33 mm, 31.58 mm, 43.80 mm, and 55.93 mm. Our data showed that zones a and c could be safely inserted three and four screws. Penetration into hip joint could be avoided when vacant 3-hole drilling was conducted in zone b. Fracture line in zone b could serve as a landmark for screw placement.
本研究旨在探讨 Stoppa 入路中关节外螺钉的放置策略。将 2016 年 1 月至 2017 年 6 月接受骨盆计算机断层扫描的患者的放射学数据导入 Materiaise 的交互式医学图像控制系统软件进行三维重建。通过入口-闭孔视图可以同时观察髋臼的上缘和下缘以及同侧骨盆边缘。从髋臼上缘画一条水平线与骨盆边缘相交于点“A”，从下缘画另一条垂直线与骨盆边缘相交于点“B”，分别测量从骶髂关节到“A”（a）、“A”到“B”（b）和“B”到耻骨联合（c）的长度。根据性别和测量的半骨盆侧别差异，将患者分为四组：男性左、男性右、女性左和女性右。还测量了不同钢板相邻孔（d）和跨不同孔（e）的长度。四组的 a、b、c 的平均长度分别为 40.94±1.85mm、40.09±1.93mm、41.78±3.62mm 和 39.77±2.23mm（P=0.078）；40.65±1.58mm、41.48±1.64mm、40.40±1.96mm 和 40.66±1.70mm（P=0.265）；57.03±3.41mm、57.51±3.71mm、57.84±4.40mm 和 59.84±4.35mm（P=0.165）。不同钢板的 d 长度平均为 12.23mm。跨越 1、2、3 和 4 个孔的平均长度分别为 19.33mm、31.58mm、43.80mm 和 55.93mm。我们的数据表明，区域 a 和 c 可以安全地插入三枚和四枚螺钉。在区域 b 进行三孔空钻时可以避免穿透髋关节。区域 b 的骨折线可以作为螺钉放置的标志。
