The lesser trochanter (small trochanter) of the femur is a conical eminence, which varies in size in different subjects.
Left hip-joint, opened by removing the floor of the acetabulum from within the pelvis.
Upper extremity of right femur viewed from behind and above.

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
- a medial continuous with the lower border of the femur neck
- a lateral with the intertrochanteric crest
- the inferior border is continuous with the middle division of the linea aspera
It can be involved in an avulsion fracture.
