[38] Femoral Shaft Fracture Flashcards

(35 cards)

1
Q

Why are femoral shaft fractures so serious?

A

Because the femur is a highly vascularised bone, so large volumes of blood (up to 1500ml) can be lost when fractured

Q

Why is it important to assess the skin with femoral shaft fractures?

A

May be open or threatened

The proximal fragment is invariably pulled into flexion and external rotation, which can further tent the skin

Q

When might further imaging via CT scanning be done in femoral shaft fracture?

A

If polytrauma is suspected

17
Q

What is the first priority in managing patients with femoral shaft fractures?

A

As per ATLS guidelines, A-E assessment, stabilise patient, ensure appropriate fluid resuscitation

18
Q

What pain relief may be required for femoral shaft fracture?

A

Often opioid analgesia +/- regional blockade, e.g. fascia iliac block

19
Q

What management do femoral shaft fractures require for the actual bone?

A

Immediate reduction and immobilisation

20
Q

Why is reducing the fracture to near anatomical alignment important in femoral shaft fractures?

A

Will ensure appropriate haematoma formation, as well as reducing pain

21
Q

How is reduction and immobilisation of femoral shaft fracture achieved?

A

In-line traction

22
Q

Give an example of a traction splint

A

Kendrick traction splint

23
Q

When are Kendrick traction splints used in femoral shaft fractures?

A

In suspected or isolated fractures of mid-shaft femur

24
Q

What are the contraindications to traction splinting for femoral shaft fractures?

A
  • Hip or pelvic fractures
  • Supracondylar fractures
  • Fractures of ankle or foot
  • Partial amputation
25
What definitive management do most femoral shaft fractures require?
Surgery
26
When might femoral shaft fractures not require surgery?
In undisplayed femoral shaft fractures in patients with significant co-morbidities
27
What may be used in undisplayed femoral shaft fractures in patients with significant co-morbidities?
Long-leg casts
28
How soon should femoral fractures be surgically fixed?
Within 24-49 hours (sooner id open)
29
How can most isolated cases of femoral shaft fractures be managed?
Integrate intramedullary nail
30
What may be required for femoral shaft fracture in unstable polytrauma or open fractures?
External fixation, with subsequent delayed conversion to intramedullary nail
31
What are the common complications of a femoral shaft fracture?
- Nerve or vascular injury - Malunion, delayed union, or non-union - Infection - Fat embolism
32
What nerves may be injured in femoral shaft fractures?
- Pudendal (around 10%) | - Femoral
33
What increases the risk of non-union of femoral shaft fractures?
- Smoking | - Increased post-op use of NSAIDs
34
What are the more long-term complications of femoral shaft fracture?
- Hip flexor or knee extensor weakness - Limb stiffness - Re-fracture
35
What reduces the complications of femoral shaft fracture?
Early mobilisation following intra-medullary nailing
