Flashcards in Fractures of femur Deck (11):
1

What demographic is intracapsular fractures common with

Elderly
Particularly women

2

Cause of intracapsular proximal femur fracture

Falling

3

Risk of intracapsular proximal femur fracture

Damage to medial femoral circumflex artery causing avascular necrosis of femoral head

4

Displacement of fragmets of intracapsular proximal femur fracture
How does this manifest clinically

Distal fragment is pulled upwards, abducted and laterally rotated
Shorter leg length - adductors and extensors
Toes point laterally - iliopsoas
Abducted - gluteus medius and minimus

5

What demographic is extracapsular proximal femur fractures common with

Young and middle aged

6

Displacement of fragmets of extracapsular proximal femur fracture
How does this manifest clinically

Distal fragment is pulled upwards, abducted and laterally rotated
Shorter leg length - adductors and extensors
Toes point laterally - iliopsoas
Abducted - gluteus medius and minimus

7

Cause of femoral shaft fractures

Traumatic injury e.g vehicle accident
They require a lot of force

8

Risks of femoral shaft fracture

Femoral nerve palsy
Compromised blood supply from femoral artery

9

Displacement of fragments in spiral fracture
How does this manifest clinically

Fragments pulled by surrounding muscles so they overlap
Presents as leg shortening

10

What are the proximal femur fractures

Intracapsular
Extracapsular

11

Treatment of extracapsular fractures

Dynamic hip screw
