Sphericity of the femoral head on anterior-posterior radiographs of dysplastic hips

Cell Mol Biol Lett. 2002;7(1):132-3.


We analyzed the sphericity of the femoral head of dysplastic hips. Using standard anterior-posterior radiographs of the hips, we assessed the femoral head's deviation from a spherical shape using a computer algorithm and via Severin grading. The method presented could serve as a useful tool to quantify differences in sphericity in cases where it is difficult to grade the hip radiologically.
