Hip Joint

Question 1

articulations of the hip joint

Answer 1

head of the femur articulates w/ acetabulum of the pelvis

Question 2

articular capsule of the hip joint

Answer 2

external layer of the joint capsule attaches proximally on the hip bone

to the bony rim of the acetabulum and to the transverse acetabular ligament

covers approximately the proximal neck of the 2/3s of the neck of the femur posteriorly

Question 3

synovial membrane of the hip joint

Answer 3

lines the fibrous layer

lines any intracapsular bony surfaces not lined with articular cartilage

Question 4

ligaments of the hip joint

Answer 4

transverse acetabular ligament

iliofemoral ligament

pubofemoral ligament

ischiofemoral ligament

ligament of the head of the femur

Question 5

transverse acetabular ligament

Answer 5

a continuation of the acetabular labrum

bridges the acetabular notch

Question 6

iliofemoral ligament is a

Answer 6

strong Y-shaped ligament

attaches to AIIS and acetabular rim and the intertrochanteric line

Question 7

what does the iliofemoral ligament do

Answer 7

reinforces the hip joint anteriorly and superiorly

prevents hyperextension of the hip joint during standing

Question 8

pubofemoral ligament goes from

Answer 8

the obturator crest of the pubic bone

then

passes laterally and inferiorly to merge w/ fibrous layer of the joint capsule

Question 9

what does the pubofemoral ligament do

Answer 9

reinforces the hip joint anteriorly and inferiorly

prevents over-ABD of the hip joint

Question 10

the ischiofemoral ligament runs

Answer 10

from the ischial part of the acetabular rim

spirals superolateral to the neck of the femur (medial to the base of the greater trochanter)

Question 11

what does the ischiofemoral ligament do

Answer 11

reinforces the hip joint posteriorly

Question 12

ligament of the head of the femur

Answer 12

primarily a synovial fold conducting a blood vessel

Question 13

movements of the hip joint

Answer 13

flexion/extension

ADD/ABD

medial-lateral rotation

circumduction

Question 14

vascular elements of the hip joint

Answer 14

medial and lateral circumflex femoral arteries

Question 15

neural elements of the hip joint

Answer 15

femoral nerve

obturator nerve

superior gluteal nerve

nerve to quadratus femoris

Question 16

angles of the femur

Answer 16

angle of inclination

angle of declination

Question 17

angle of inclination

Answer 17

long axis of the head and neck projects superomedial at an angle to that of the obliquely oriented shaft

angle can be b/w 115-140 degrees

allows for greater mobility of the femur at the hip joint

Question 18

in what gender is the angle of inclination less

Answer 18

females

Question 19

how does the angle of inclination allow for greater mobility

Answer 19

places the head and the neck more perpendicular to the acetabulum

Question 20

coxavera

Answer 20

reduced angle of inclination

more forces are put upon the neck of the femur (more likely to fracture)

shortens a person’s leg

Question 21

coxavalga

Answer 21

increases angle of inclination

lengthens the person’s leg

reduces the bone congruency (less stable at the joint)

Question 22

angle of declination

Answer 22

torsion angle

angle b/w long axis of the head and neck of the femur and the transverse axis of femoral condyles

Question 23

average degrees for males and females (torsion angle)

Answer 23

males: 7 degrees

females: 12 degrees

Question 24

what does the torsion angle do with the angle of inclination

Answer 24

allows for rotary movements of the femoral head within the obliquely placed acetabulum

Question 25

anterversion

Answer 25

increases the angle of declination

Question 26

retroversion

Answer 26

decreases the angle of declination
