SI and Hip

Question 1

Attachments of sacrotuberous ligament

Answer 1

posterior iliac spine & lateral margin of sacrum to ischial tuberosity

Question 2

Attachments of sacrospinous ligament

Answer 2

ischial spine to lateral margin of the sacrum

Question 3

Attachments of fibrous joint capsule

Answer 3

margin of acetabulum to the neck, intertrochanteric line and crest of femur

Question 4

Attachments of iliofemoral

Answer 4

anterior inferior iliac spine to the intertrochanteric line of the femur

Question 5

Attachments of pubofemoral

Answer 5

iliopubic eminence and superior pubic ramus to fibrous capsule

Question 6

Attachments of ischiofemoral

Answer 6

ischium posterior to acetabulum to the greater trochanter & iliofemoral ligament

Question 7

Attachments of ligamentum teres (ligament of the head of the femur)

Answer 7

fovea of the femoral head to the acetabular notch

Question 8

Function of iliofemoral ligament

Answer 8

limits extension of the femur on the acetabulum, taught with femoral external rotation and internal rotation

Question 9

Function of pubofemoral ligament

Answer 9

limits abduction of the femur, tightens up in extension and external rotation of hip

Question 10

Function of ischiofemoral ligament

Answer 10

assists the iliofemoral ligament in limiting extension of the femur; tightens up in internal rotation and adduction

Question 11

Arthrokinematics of hip flexion

Answer 11

spin with slight inferior and posterior glide at terminal motion

Question 12

Arthrokinematics of hip extension

Answer 12

spin with slight anterior and superior glide at terminal motion

Question 13

Arthokinematics of hip external rotation

Answer 13

anterior glide

Question 14

Arthokinematics of hip internal rotation

Answer 14

posterior glide

Question 15

Arthrokinematics of hip adduction

Answer 15

superior glide

Question 16

Arthrokinematics of hip abduction

Answer 16

inferior glide

Question 17

Synovial classification of sacroiliac joint

Answer 17

planar

Question 18

Synovial classification of hip joint

Answer 18

ball & socket

Question 19

Nutation of sacrum on innominate

Answer 19

Top of the sacrum moves anterior-inferior, bottom of the sacrum moves superior-posterior

Inferoposterior glide

Question 20

Counter nutation of sacrum on innominate

Answer 20

Superior aspect of sacrum moves posterior; inferior aspect moves anterior

Anterosuperior glide

Question 21

Normal angle of inclincation

Answer 21

125°

Question 22

Coxa vara

Answer 22

decreased angle of inclination (115°); more of the femoral head is covered by the acetabulum

Question 23

Coxa valga

Answer 23

increased angle of inclination (140°); reduced coverage of femoral head by acetabulum

Question 24

Normal angle of torsion

Answer 24

8-15°

Question 25

Excessive anteversion

Answer 25

Increased angle of torsion; in-toeing to center femoral head

Question 26

Retroversion

Answer 26

Decreased angle of torsion; toe out to center femoral head

Question 27

What is the lunate surface of the acetabulum closed off by?

Answer 27

transverse acetabular ligament
