The Hip

Question 1

The hip joint is a ………… joint

Answer 1

Ball and socket

Question 2

What are the articular surfaces of the hip joint?

Answer 2

Head of the femur, lunate surface of the acetabular

Question 3

What is the acetabulum formed by?

Answer 3

The ischium, ilium, pubic bones

Question 4

What is the Acetabular labrum?

Answer 4

Tough cartilage which lines the Acetabular rim to prevents bones from rubbing together.

Question 5

Where does the hip joint capsule attach?

Answer 5

Acetabulum, transverse acetabular ligament, Obturator foreman

Question 6

Capsular ligament: iliofemoral attachments?

Answer 6

attaches the anterior inferior iliac spine (AIIS) to the intertrochanteric crest of the femur.

Question 7

Iliofemoral ligament function?

Answer 7

Prevents hyperextension when standing. During extension the ligament tightens holding the femoral head in place in the acetabulum.

Question 8

Capsular ligament: pubofemoral attachment?

Answer 8

its base attaching to the iliopubic eminence, superior pubic ramus, obturator crest and obturator membrane.

Question 9

Function of the pubofemoral ligament?

Answer 9

stabilizes the hip joint. It prevents the joint from moving beyond its normal range of motion, front-to-back and side-to-side. It also limits external rotation of the joint.

Question 10

Capsular ligament: ishiofemoral attachment?

Answer 10

From the ischium behind the acetabulum and it attaches to the base of the greater trochanter.

Question 11

Ishiofemoral ligament function?

Answer 11

Prevents excessive extension.

Question 12

Intracapsular ligaments: transverse ligament of acetabulum

Answer 12

Is Strong and flat, bridges the Acetabular notch creating acetabular foramen where neurovascular structures enter.

Question 13

Intracapsular ligament: ligamentum teres capitis femoris

Answer 13

connects the femoral head to the acetabulum. It is important in providing hip stability and supplies blood to the femoral head.

Question 14

Innervation of the hip joint?

Answer 14

Nerves emerging from lumboscral pelvis (L2-S1)
FEMORAL NERVE 
OBTURATOR NERVE
SUPERIOR GLUTEAL NERVE 
NERVE TO QUADRATUS FEMORIS

Question 15

Blood supply to the hip joint?

Answer 15

Blood supply comes from the medial and lateral circumflex femoral arteries, obturator arteries, superior and gluteal arteries. This network gives rise to the retinacular arteries which supply the greatest amount of blood to the femur head and neck.

Question 20

Muscles for hip internal rotation?

Answer 20
