From its apex three well-marked borders extend:

• two of these are above
  • a medial continuous with the lower border of the femur neck
  • a lateral with the intertrochanteric crest
    Intertrochanteric crest
    The intertrochanteric crest is a bony ridge located on the posterior side of the head of the femur, stretching obliquely downward and medially from the summit of the greater trochanter to the lesser trochanter....
    
    
• the inferior border is continuous with the middle division of the linea aspera
  Linea aspera
  The linea aspera is a ridge of roughened surface on the posterior aspect of the femur, to which are attached muscles and intermuscular septum.Its margins diverge above and below....
  
  

The summit of the trochanter is rough, and gives insertion to the tendon of the Psoas major and the Iliacus.
