Flashcards in Lecture: Lower Limb 1: Pelvis and Hip Joint Deck (13):
1

Name the area where the 3 hip bones fuse

The acetabulum

2

the 3 bones of the hip?

L and R Inominate (hip) bones
+ Sacrum

3

What contributes to the stability of the hip joint?

Acetabular anatomy
Fibrous capsule around all of joint
Ligaments x3

4

name the ligaments involved in the hip joint

Ileofemoral
Pubofemoral
Ischofemoral

5

What is the acetabular labrum

rim of cartilage which deepens the articular surface
nothing inferior in acetabulum, just cartilage (acetabular notch)

6

describe the iliofemoral ligament

covers superior and anterior
from ilium to femur
strongest ligament
spiral rounds
prevents hyperextension of hip while standing

7

describe the pubofemoral ligament

covers inferior and anterior
prevents excessive abduction

8

describe the ischiofemoral ligament

posterior
weakest one

9

typical injuries at the hip?

fractured Neck of Femur (#NOF)
dislocation of hip joint
fractures of the pelvic ring

10

characteristics of posterior dislocation of the hip joint

limb appears shortened and internally rotated
sciatic nerve injury may occur

11

characteristics of anterior dislocation of the hip?

occurs when force is applied during extreme abduction with external rotation of the hip
limb appears externally rotated, abducted and flexed

12

What is Developmental Dysplasia of the Hip (DDH)?

acetabulum not deep enough to accomodate head of femur
varies in severity

13

what movements are possible at the hip?

flexion
extension
abduction
adduction
external/internal rotation
