The lesser trochanter is a conical posteromedial projection of the shaft of the femur, projecting from the posteroinferior aspect of its junction with the femoral neck. [1] The summit and anterior surface of the lesser trochanter are rough, whereas its posterior surface is smooth. [1] From its apex three well-marked borders extend: [2]
While the exact origin of the anatomical term "trochanter" is uncertain, multiple possible connections could be suggested. One possibility is that the term was derived directly from the Greek roots without influence from the maritime meaning, with the name referencing the trochanter’s role in enabling swift movement through muscle attachment.
In these taxa, the trochanteric fossa is the insertion point for the puboischiofemoralis externus muscle. In turtles , the intertrochanteric fossa is bounded anteriorly by the trochanter minor (sometimes called the lesser trochanter) and posteriorly by the trochanter major (sometimes called the greater trochanter; neither of these structures is ...
In the remaining cases, it is either inserted into the upper part of the pectineal line or the posterior part of the lesser trochanter. While similar to its neighbouring adductors, it is formed by separation from the superficial layer of the obturator externus, and is thus not ontogenetically related to the adductors. [5]
The distal capsular attachment on the femur follows the shape of the irregular rim between the head and the neck. As a consequence, the capsule of the hip joint attaches in the region of the intertrochanteric line on the anterior side, but a finger away from the intertrochanteric crest on the posterior side of the head.
Above, the linea aspera is prolonged by three ridges. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter.It is termed the gluteal tuberosity, and gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is ...

Same point of view as above of right femur from behind. Greater trochanter is labeled at right. The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2–4 cm lower than the femoral head. [1]
