Mild asphericity of femoral head

WebMost patients with FAI have a cam deformity, characterized by a reduction of offset or abnormal asphericity at the anterolateral femoral head-neck junction (Beck et al. 2005). This may be recognized by radiography (Clohisy et al. 2008 ), CT (Beaule et al. 2005 ), and MRI (Notzli et al. 2002 ), and quantified by measuring the alpha angle (Notzli et al. 2002 ) … Web20 nov. 2008 · We (CA, MD) measured the shape of the femoral head-neck junction using the radial slices of the MRA in 14 cuts around the femoral head-neck.
