Femoroacetabular impingement syndrome - The Radiology Assistant In Cam morphology, the femoral head has an abnormal shape, often appearing more oval than spherical, which causes abnormal contact with the acetabulum This can lead to cartilage damage and hip pain, particularly during activities involving hip rotation or flexion
Comparison of Six Radiographic Projections to Assess Femoral . . . - LWW To radiographically quantify femoral head asphericity, we measured the angle where the femoral head neck leaves sphericity (angle alpha) The aspherical femoral head neck contours had a greater maximum angle alpha (70°) compared with the spherical head neck contours (50°)
Correlations between the alpha angle and femoral head asphericity . . . The objective of this study was to correlate 3D model-based measurements of true femoral head asphericity (i e maximum deviation from a best-fit sphere) to alpha angles measured on five radiographic and four radial CT views
Three-dimensional analysis of age and sex differences in femoral head . . . The purpose of this study was to investigate the asphericity of the femoral head during skeletal growth and maturation in children and adolescents with asymptotic hips using 3D image analysis and to propose a new 3D metric for asphericity analysis termed the asphericity index
