A Prospective Cohort Study on the Morphometric Analysis of Anterior Column of the Acetabulum & Safety of Intramedullary Screw Fixation for its Fractures Using 3D-CT Pelvis

Diwank Agrawal | R.C. Banshiwal | Ayush Gupta


Abstract: Background: There has been an upwards trend towards minimally invasive fixation of simple acetabular fractures. Compared to plate osteosynthesis which is a challenging task due to the anatomic complexity of acetabulum, lag screw fixation has been proven to attain anatomic reduction and interfragmentary compression with good clinic outcomes. Materials and Methods: CT scans of 95 uninjured adult pelvis were analysed. The axis of an anterior column was derived by joining the centres of its narrowest zones around the acetabulum proximally and the superior pubic ramus distally. Two types of screw trajectories along the axis of the anterior column were created based on the standard 4-mm and 6.5-mm screws. For the screw trajectories which passed safely through the narrow zone around the acetabular region safely, the trajectory lengths were limited to the point of first cortical perforation anywhere lateral the pubic tubercle. Results and Conclusion: In males, 4mm screws are applicable in 52 subjects out of 58 (89.66%) and 6.5mm screws are applicable in 36 out of 58 (62.07%) subjects. Similarly, in females, 4mm screws are applicable in 27 subjects out of 37 (72.97%) and 6.5mm screws are applicable in 12 out of 37 (32.43%) subjects. The p value of our data is 0.0005 which is significant. To conclude, the results provided in our study can form the basis of a larger prospective and anthropometry based study on the anterior column of the acetabulum.
