The lesser trochanter (small trochanter) of the femur is a conical eminence, which varies in size in different subjects
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.
Clinical significance
It can be involved in an avulsion fracture.[1]
