Lesser trochanter
Other Terms:
Lesser trochanter of femur,
Trochanter minor,
Petit trochanter
Description
The lesser trochanter is the smaller posterior projecting protuberance at the medial base of the femoral neck. It serves as the site of attachment for the psoas major, iliacus, and upper part of the adductor magnus muscles.
Etymology
The word trochanter is derived from the Greek words trechein to run and trochos meaning wheel. Galen originally applied this term to the head of the femur because it resembled a wheel as it turned in the acetabular socket. The term was later transferred to the adjacent bony projections at the proximal end of the femur, probably in reference to their attachment site for muscles that produce rotary movements of this bone.
