AB  - Within  the  scope  of  this  chapter,  the  sacrum,  innominates  (including  the  acetabulum),  and  proximal  femur  are  discussed.  Features  of  the  proximal  femur  are  of  particular  interest  because  of  their  frequent  pathologic  involvement.  The  femoral  head  comprises  approximately  two-thirds  of  a  sphere  with  an  orientation  medially,  superiorly,  and  anteriorly  to  articulate  with  the  acetabulum.  The  surface  of  the  femoral  head  is  covered  with  articular  cartilage  with  the  exception  of  the  fovea.  The  cartilage  is  thickest  centrally  and  is  slightly  attenuated  peripherally;  the  fovea  is  devoid  of  articular  cartilage.  Connecting  the  head  and  the  shaft  of  the  femur  is  the  neck  extending  inferolaterally.  The  femoral  neck  has  considerable  variability  in  morphology  and  forms  an  angle  of  approximately  130°  with  the  femoral  diaphysis,  which  is  an  important  angle  of  reference.  Surrounding  the  femoral  neck  are  the  circumflex  arteries,  which  give  rise  to  much  of  the  blood  supply  to  the  femoral  head.  From  the  medial  femoral  circumflex  artery  arises  the  lateral  epiphyseal  artery,  which  provides  the  majority  blood  supply  to  the  femoral  head.1
