Question 8 The femoral head articulates with a fossa named the [fill in].
acetabulum
Question 9 The [fill in] is the most lateral aspect of the femur.
greater trochanter
Question 10 Hyperextension of the hip or iliofemoral joint is limited by the strongest ligament in the body known as the [fill in] ligament. There are two possible answers to this question.
Y
iliofemoral
Question 11 The neutral position of the pelvis is attained if the [fill in] and the
[fill in] lie in the same frontal plane.
Answer 1:
pubis
ASIS
anterior superior iliac spine
pubic bone
Answer 2:
anterior superior iliac spine
ASIS
pubis
pubic bone
Question 12 The [fill in] is described by a line passing through the head and neck of the femur and a line inscribed by the femoral condyles.
angle of anteversion
Question 13 According to William Hamilton, the smaller the angle of inclination and the longer the femoral neck, the greater range of [fill in] a dancer is likely to have in his/her/their natural structure.
Any of these:
external rotation
turnout
lateral rotation
Question 14 The hip, or iliofemoral joint, is a tri-axial joint of this type.
A) synovial
B) cartilaginous
C) fibrous
D) semi-moveable
synovial

.
adduction
flexion
lateral rotation

Question 16 The bones that form the acetabulum are the 1[fill in], 2[fill in], and 3[fill in].
Answer 1:
ilium
ischium
pubis
Answer 2:
ischium
ilium
pubis
Answer 3:
pubis
ilium
ischium
Question 17 Why might a dancer be able to turn out (lateral femoral rotation) more with his/her/their pelvis tilted anteriorly? (Katarina’s Response)
A dancer would experience greater turnout because it reduces the grip of the iliofemoral and pubofemoral ligaments.
Feedback: Yes, when the pelvis is tipped anteriorly the Y ligament is relaxed. The Y ligament limits external rotation.
Question 18 What is the anatomical definition of turn out (lateral femoral rotation)? (Katarina’s Response)
Anatomically, the greater trochanter moves toward the back and closer to the ischial tuberosity during turnout or lateral femoral rotation.
Question 19 Why do dancers often have a greater range of hyperextension at the iliofemoral joint than non-dancers? (Katarina’s Response)
For dancers, the Y ligament becomes stretched out so they can have a larger range of motion during hyperextension compared to the general population.
What are three reasons that could account for a dancer having difficulty achieving a “neutral” pelvis? (Katarina’s Response)
- Weak core/abs
- Shortened or tight lower back muscles
- Short or tight quads
