The thigh bone had a lesser trochanter that was clearly lower than the greater trochanter; the fourth trochanter was well-developed.
12.
The proximal femur displays a trochanteric shelf caudal to the lesser and greater trochanters, a feature distinguishing non-tetanurans theropods from Tetanurae.
13.
The fibers of the muscle converge into a strong flattened tendon that inserts on the lateral surface of the greater trochanter.
14.
*Proximally the femur is largely covered by muscles and, as a consequence, the greater trochanter is often the only palpable bony structure.
15.
More specifically, the muscle's tendon inserts into an oblique ridge that runs downward and forward on the lateral surface of the greater trochanter.
16.
The targeted region should be aimed inferior to the most prominent aspect of the greater trochanter, and medial to the landmark of the proximal femur.
17.
Because the pelvic outlet in the female is larger than in the male, there is a greater distance between the greater trochanters in the female.
18.
It blends with the lower part of the tendon of the Obturator internus, and is inserted with it into the medial surface of the greater trochanter.
19.
In archosaurs and especially in dinosaurs, the intertrochanteric fossa is highly developed as both the internal / lesser trochanter and the greater trochanter are better developed.
20.
The inferior division crosses the gluteus minimus obliquely to the greater trochanter, distributing branches to the gluteal muscles and anastomoses with the lateral femoral circumflex artery.
