Lesser trochanter of femur

Recommended video: Femur [12:12]
Anatomy and function of the thigh bone.

The lesser trochanter of the femur is a rounded apophysis projecting from the posteromedial part of the junction of the shaft and neck of the femur. It has a rough apex and anterior surface, whilst the posterior surface is smooth. It is connected to its larger counterpart, the greater trochanter, by two lines: the intertrochanteric line on the anterior aspect and the intertrochanteric crest on the posterior aspect of the proximal femur.

The lesser trochanter is the insertion point for the iliacus and psoas major muscles (iliopsoas). 

Terminology English: Lesser trochanter of femur
