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

[edit] Anatomy
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
The summit of the trochanter is rough, and gives insertion to the tendon of the Psoas major.
[edit] Clinical significance
It can be involved in an avulsion fracture.[1]
