Hip Joint

Question 1

Hip joint

Answer 1

Synovial, joint ball and socket

Articulation of the head of the femur, and the acetabulum of the os Coxa

Question 2

Acetabulum

Answer 2

Deepened by the acetabular labrum
This labrum attaches to the bony rim and the transverse acetabular ligament

Question 3

Transverse acetabular ligament

Answer 3

Spans the acetabular notch creating the acetabular foramen

Acetabular foramen provides passage of blood vessels and nerves to the joint cavity

Question 4

Femur

Answer 4

Attached to the transverse acetabular ligament and the acetabular labrum by the ligament of the head of the femur, also known as ligamentum teres femoris

Attachment of the ligament is marked on the femur by the fovea Capitis

Question 5

Four thickening of the joint capsule to help strengthen it

Answer 5

Iliofemoral ligament or y ligament
Ischiofemoral ligament
Pubofemoral ligament
Zona Obicularis

Question 6

Illiofemoral ligament or y ligament

Answer 6

Extends from the anterior inferior iliac spine and acetabular rim to the intertrochanteric line

It is taught in extension and prevents hyperextension of the hip in standing

Question 7

Ischiofemoral ligament

Answer 7

Extends from the acetabulum posteriorly and spirals superiorlaterally to the neck of the femur and greater trochanter

It helps prevent hyperextension

Question 8

Pubofemoral ligament

Answer 8

Extends from the pubic part of the acetabulum and superior ramus to the lower part of the intertrochanteric line

It is taut in extension and abduction and helps prevent excessive abduction

Question 9

Zona orbicularis

Answer 9

Capsular fibers encircle the neck of the femur

Question 10

Two extension of the hip joint synovial capsule

Answer 10

They serve as bursa

Anteriorly- opening creates a bursa under the tendon of the iliopsoas

Posteriorly- opening in a capsule creates a bursa for the tendon of the obturator externus muscle

Question 11

Blood supply for hip joint

Answer 11

Medial and lateral femoral circumflex arteries

Artery to the head of the femur

Question 12

innervation of hip joint

Answer 12

Femoral nerve
Obturator nerve
Superior gluteal nerve
Nerve to quadratus femoris

Question 13

Angle of wiberg

Answer 13

It’s about how much shelf space that you have
How much of an acetabulum rim do you have surrounding the head of the femur
For adequate weight bearing and support to the joint

Question 14

Shentons line

Answer 14

Forms a nice arc from the inferior edge of the neck of femur to the inferior edge of the superior pubic ramus

If there’s a break in this line it could indicate a fracture of the femur

Question 15

Illioischial line

Answer 15

Coming from the illium to the ischium

A break in the line would indicate there’s a problem with acetabular wall

Question 16

Illiopectineal line or iliopubic line

Answer 16

A problem with this line would indicate a problem with acetabular wall
