Lesser trochanter

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 neck.

From its apex three well-marked borders extend:
 * two of these are above
 * a medial continuous with the lower border of the 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.
