Ligaments of the Hip Joint

Question 1

Name 4 ligaments of the hip joint and their location

Answer 1

Iliofemoral ligament (anterior)
Pubofemoral ligament(anterior)
Ischiofemoral ligament(posterior)
Ligamentum Teres (interior)

Question 2

State the attachments and action of the iliofemoral ligament

Answer 2

Formed by two bands, superior and inferior
Apex: AIIS
Base: to the intertrochanteric line

Superior band limits adduction and extension

Inferior band limits abduction and extension

Question 3

State the attachments of the pubofemoral ligament

Answer 3

Base: from the pubic eminence
Apex: to the capsule and medial band of the iliofemoral ligament and intertrochanteric line

Question 4

What does the pubofemoral ligament limit?

Answer 4

It limits extension and abduction

Question 5

State the attachments of the ischiofemoral ligament and its limitations

Answer 5

From: inferior aspect of the ischium
To: The capsule and the anterior part of the greater trochanter deep to the iliofemoral ligament.

It limits extension and medial rotation

Question 6

Where is the ligamentum Teres located?

Answer 6

From a pit (fovea) in the head of the femur to the acetabular notch and transverse acetabular ligament

Question 7

What is the function of the in inguinal ligament?

Answer 7

It connects the ASIS to the pubic tubercle

Question 8

What factors contribute to hip joint stability?

Answer 8

Strong surrounding ligaments
Cup shaped acetabulum deepened by the acetabular labrum
Strong capsule
Vacuum shaped effect of the ball and socket joint
Oblique angle of femoral head
Arrangement of powerful surrounding muscles

Question 9

What are the limitations to ROM?

Answer 9

Tension of antagonists
Soft tissue apposition
Tension of ligaments limit range
Relative congruency of the articular surfaces

Question 10

State the hip Range of Motion for flexion and extension

Answer 10

Flexion- 100-120 degrees

Extension- 15-20 degrees

Question 11

What contributes to maximum to hip joint stability?

Answer 11

Close-pack position of the hip.
Max ext
Medial rotation and abduction

Question 12

Describe the Sacroiliac-iliac Joint

Answer 12

Synovial, plane joint
Ridged articular surfaces
Joint mutation: nutation and counter-nutation

Question 13

State the attachments of the SIJ

Answer 13

Attached to the margins of the articular surfaces of sacrum and ilium
Lined with synovial membrane

Question 14

State the attachment and function of the Ventral sacroiliac-iliac ligament

Answer 14

From the lateral sacrum to the medial aspect of the ilium.
Thickening of the capsule
Provides anterior stability

Question 15

State the attachment and limitations of the sacrtuberous ligament

Answer 15

From PSIS, Sacral tubercles, lateral margins of sacrum and coccyx to the ischial tuberosity and ischial ramus.

It limits nutation of the sacrum and posterior rotation of the ilium

Question 16

What does the sacrospinous ligament limit?

Answer 16

Nutation of the sacrum and posterior rotation of the ilium

Question 17

State the ilio-lumbar ligament

Answer 17

Upper band:
From transverse processes of L5 to posterior aspect of the iliac crest.

Lower band:
From transverse processes of L5
To anterior sacrum and ventral sacro-iliac ligament

Question 18

What type of joint is the symphysis pubis?

Answer 18

Secondary cartilaginous joint
