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.
