Hip Joint

Question 1

Type of joint

Answer 1

Synovial, polyaxial, ball and socket joint

Question 2

Position

Answer 2

articulation between the head of the femur and the acetabulum of the inorminate bone.

Question 3

Acetabulum

Answer 3

.
A cup shaped articular fossa that faces laterally, anteriorly and inferiorly.
Is a hemispherical hollow formed by the fusion of the ilium, ischium and pubis. Contains a horseshoe shaped lunate articular surface covered in hyaline cartilage, thickest superiorly. Central section is non-articular where ligamentum teres arises.
-Rim is not complete inferiorly (acetabular notch) spanned by the transverse ligament.
Fossa deepened by fibrocartilaginous labrum which attaches to the rim of the acetabulum

Question 4

Head of the femur

Answer 4

-hemisphere
hyaline cartilage deficienet at the fovea
thickest centrally
-Head is carried on angled neck.

Question 5

Movements

Answer 5

3 degrees of movement
Flexion/Extension (Sagittal plane)
Abduction/Adduction (Frontal plane)
Medial and Lateral Rotation (Transverse plane)

Question 6

Capsule

Answer 6

Surrounds the acetabulum, labrum and transverse ligament.

on the femur:
Anteriorly to intertrocanteric line. 
-base of the neck of the femur. 
-Posteriorly to the neck above the trochanteric crest. 
-inferior neck of femur

Question 7

Synovial Membrance

Answer 7

lines internal capsule
covers acetabular labrum
attached to the transverse ligament
covers fatty tissue in acetabular fossa
attaches to edges of fovea capitis extending around the head of the femur
reflected back to the capsule attachment
communicates with psoas bursa

Question 8

Ligaments

Answer 8

Transverse ligament

Question 9

Transverse ligament

Answer 9

spans the acetabular notch

Question 10

Ligamentum teres

Answer 10

fovea capitis to the the acetabular notch and transverse acetabular ligament

Question 11

Iliofemoral Ligament

Answer 11

AIIS To the intertrochanteric line

limits extension and abduction

Question 12

Pubofemoral Ligament

Answer 12

pubic eminence to lower part of introchanteric line blending with Iliofemoral Ligament

limits extension and abduction

Question 13

Ischiofemoral Ligament

Answer 13

body of the ischium spiraling to the anterior part of the
greater trochanter

limits extension and medial rotation

Question 14

Inguinal (ligament)

Answer 14

ASIS to pubic tubercle
