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|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]].
