目的:探讨髋臼前柱的解剖学结构和螺钉放置的安全角度范围。
方法:取20具骨盆标本,在X线透视下确定髋臼上缘距髂前下棘顶点和髋臼下缘距髂外血管鞘外缘与骨盆缘交点的距离,CT垂直扫描前柱,测量距髋臼上缘0.5～4.0cm(每0.5cm测1次)的CT断面上前柱宽、髋臼宽。根据髋臼在前柱表面的投影,将前柱分为髋臼区、相对危险区和危险区,并测量距骨盆缘1cm处2.5cm螺钉进钉的安全角度。
结果:髋臼上缘在髂前下棘顶点上(1.1±0.1)cm,髋臼下缘在髂外血管鞘外缘与骨盆缘交点下(1.7±0.2)cm,距髋臼上缘0.5、1.0、1.5、2.0、2.5、3.0、3.5、4.0cm的CT断面上,前柱平均宽分别为(55.7±4.8)、(54.4±2.0)、(50.5±3.7)、(41.3±3.0)、(39.1±4.6)、(35.2±5.7)、(31.7±5.6)、(30.8±3.4)mm;髋臼宽分别为(28.2±6.2)、(34.7±5.5)、(36.8±5.2)、(34.8±2.7)、(37.0±4.2)、(33.2±5.1)、(29.6±5.7)、(28.0±3.9)mm;距髋臼上缘0.5cm断面进钉安全角度应<87°±8°;距髋臼上缘1.0cm断面进钉的安全角度应<76°±7°;距髋臼上缘15cm断面进钉的安全角度应<69°±7°。 |

| Anatomical study of projection of the anterior column of the acetabulum |

Abstract:
Objective:To investigate the anatomical configuration of the anterior column of the acetabulum and to fine a safe path for screw placement into it.
Methods:Twenty pelvis specimens were used to test the distance from the anterior inferior iliac spine(AIIS) to the superior acetabular margin(SAM),and from the point of intersection of pelvic brim and external iliac vessel(PPEV)to the inferior acetabular margin(IAM).CT scan was performed.The plane of the cross-section was perpendicular to the anterior column.The average width of the anterior column and the acetabulum at 0.5～4.0 cm inferior to the superior acetabular boundary was tested.In according of projection of the acetabulum onto the anterior surface of the anterior column,the anterior column was divided into the acetabulum region,relatively danger zone,and danger zone.The safe angulation of screw placement was also calculated.
Results:The distance from AIIS to SAM and from PPEV to IAM were (1.1±0.1) cm and (1.7±0.2) cm respectively.The average width of the anterior column at 0.5、1.0,1.5,2.0,2.5,3.0,3.5,4.0 cm inferior to the superior acetabular boundary were(55.7±4 8),(54.4±2 0),(50.5±3.7),(41.3±3.0),(39.1±4 6),(35.2±5.7),(31 7±5.6),(30.8±3.4) mm.The average width of the acetabulum were (28.2±6.2),(34.7±5.5),(36.8±5.2),(34 8±2.7),(37.0±4.2),(33.2±5.1),(29.6±5.7),(28.0±3.9) mm;The safe angulation of screw placement at various section should be<63°±7°.
Conclusion:For fixation of the acetabular fracture,screws should place in the superior pubic ramus or the ilium out of the middle part of acetabulum,and the safe angulation of screw placement should be<63°±7°. |
