Anatomy

The intertrochanteric crest is a prominent smooth bony ridge upon the posterior surface of the

at the junction of the

and the shaft of the femur; together with the

intertrochanteric line The intertrochanteric line (or ''spiral line of the femur''White (2005), p 256 ) is a line located on the anterior side of the proximal end of the femur. Structure The rough, variable ridge stretches between the lesser trochanter and the greater t ...

on the anterior side of the head, the intertrochanteric crest marks the transition between the femoral neck and shaft. The intertrochanteric crest extends between the

superiorly, and the

inferiorly; it passes obliquely inferomedially from the greater trochanter to the lesser trochanter. An elevation between the middle and proximal third of the crest is known as the

quadrate tubercle The quadrate tubercle is a small tubercle found upon the upper part of the femur. It serves as a point of insertion of the quadratus femoris muscle, along with the intertrochanteric crest and the linea quadrata. Structure The quadrate tubercle ...

Relations

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
