Anatomical terms of bone

The lesser trochanter (small trochanter) of the femur is a conical eminence, which varies in size in different subjects.


It projects from the lower and back part of the base of the femur neck.

From its apex three well-marked borders extend:

  • two of these are above
  • the inferior border is continuous with the middle division of the linea aspera

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

Clinical significance[edit]

It can be involved in an avulsion fracture.[1]
