Intertrochanteric crest
The intertrochanteric crest is a bony ridge located on the posterior side of the head of the femur, stretching obliquely downward and medially from the summit of the greater trochanter to the lesser trochanter.
Together with the intertrochanteric line on the anterior side of the head, the crest marks the transition between the neck of the femur and the shaft of the femur. An elevation between the middle and proximal third of the crest is known as the quadrate tubercle. The upper half of the crest forms the posterior border of the greater trochanter.
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.
