Hip Joint

Question 1

Iliofemoral Joint Joint:
What is the Open packed Position? Closed Packed Position? Capsular Pattern?

Answer 1

Open Packed Position: 30 degrees flexion, 30 degrees abduction, slight external rotation
Closed Packed Position: full extension, internal rotation
Capsular Pattern: flexion > abduction > internal rotation (according to score builders)

(Sometime IR is most limited)

CP: internal rotation > flexion > abduction = extension > all other motions

Question 2

What is the orientation of the acetabulum?

Answer 2

Laterally

Inferiorly

Anteriorly

Question 3

Which muscles produce hip flexion?

Answer 3

iliopsoas
sartorius
rectus femoris
pectineus

Question 4

Which muscles produce hip extension?

Answer 4

Gluteus Maximus
Gluteus Medius
Semitendinosus
Semimembranosus
Biceps Femoris

Question 5

Which muscles produce hip abduction?

Answer 5

Gluteus Medius
Gluteus Minimus
Piriformis
Obturator Externus
Tensor Fasciae Latae

Question 6

Which muscles produce hip adduction

Answer 6

Adductor Magnus
Adductor Longus
Adductor Brevis
Gracilis

Question 7

Which muscles produce hip internal rotation?

Answer 7

TFL
Gluteus Medius
Gluteus Minimus
Pectineus
Adductor Longus

Question 8

Which muscles produce hip external rotation?

Answer 8

Gluteus Maximus
Piriformis

Question 9

What is the acetabular labrum?

Answer 9

A fibrocartilaginous rim attached to the margin of the acetabulum?

Enhances the depth of the acetabulum.

Question 10

Articular Capsule?

Answer 10

Extends from the rim of the acetabulum to the neck of the femur.

Capsule is reinforced by the: Iliofemoral. Pubofemoral, Ischiofemoral ligaments

Question 11

What are the bursae of the hip?

Answer 11

Iliopsoas Bursae: located between the anterior joint capsule and the iliopsoas tendon.

Trochanteric Bursae: (there are several of them)
- located between the greater trochanter and several gluteal muscles

Ischiogluteal Bursae: located between the ischium and the gluteus maximus

Question 12

What is the femoral triangle and its borders?

Answer 12

Space that is located on the anterior hip

BORDERS:
Adductor Longus
Sartorius
Inguinal Ligament

Question 13

What structures are found in/pass through the femoral triangle?

Answer 13

Femoral Artery
Lymph Gland/Nodes
Femoral Nerve
Femoral Vein

Question 14

What is the attachment sites of Ischiofemoral ligament?

Answer 14

Ischial wall of the acetabulum
to
Neck of the Femur

Question 15

What is the Ischiofemoral ligament and its functions?

Answer 15

[Weakest of the three ligaments]
- Role in reinforcing the articular capsule

Question 16

What is the attachment sites of the iliofemoral ligament?

Answer 16

Anterior Inferior Iliac Spine (AIIS)
to
Intertrochanteric Line of the femur

Question 17

What is the Iliofemoral ligament and its functions?

Answer 17

Considered to be the strongest ligament of the body.

Prevents hip excessive hip extension and assists in maintaining posture.

“Y ligament of Bigelow” - “Resting on your Y’s”

Question 18

What is the Ligamentum Teres?

Answer 18

[ligament of the head of the femur]

• serves as a physical attachment between the head of the femur and the inferior rim of the acetabulum
• Can fine the blood vessels and nerves that travel in a sheath to the head of the femur.
• provides minimal stability to the hip

Question 19

What is the pubofemoral ligament and its functions?

Answer 19

Prevents excessive abduction of the femur

Limits hip extension

Question 20

What is the attachment sites of the pubofemoral ligament?

Answer 20

Extends from the pubic portion of the rim of the acetabulum

to

neck of the femur
