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.
