Fractures Flashcards

1
Q

Fractures may result from…

A
  1. single, highly stressful, traumatic incident (traumatic #)
  2. repetitive stress of normal degree persisting to point of mechanical fatigue (stress #)
  3. normal stress acting on an abnormally weakened bone (pathological #)

Q

How are fractures reduced?

A

With an open (surgical) or closed procedure.

17
Q

What further treatment may complicated fractures require?

A
  • antibiotic treatment
  • debridement
  • irrigation
  • dressings
18
Q

How long does a fracture take to heal?

A

A fracture without complications will heal in 6-16 weeks.
Callus visible: 2-3 weeks
Union: 8-12 weeks
Consolidation: 12-16 weeks

19
Q

A
  • osteomyelitis
  • delayed union, non-union or mal-union
  • avascular necrosis
  • joint problems
  • shortening of the bone
  • osteoarthritis
20
Q

What soft tissue complications can arise from fractures?

A
  • nerve or vascular damage
  • compartment syndrome
  • CRPS
21
Q

What is a pilon ankle fracture?

A

of metaphysical area of distal tibia (and sometimes fibula) extending to articular surface.

22
Q

How are pilon ankle fractures classified?

A

RUEDI-ALLGOWER

  1. malleolar # with large posterior plafond fragments
  2. spiral extension #
  3. central compression # w/ or w/o fibula #
23
Q

What is the Lauge Hansen Classification System?

A

A way of classifying ankle fractures by their MOI.

  • Supination/adduction Injuries
  • Supination/external rotation injuries
  • Pronation/Abduction injuries
  • Pronation/External Rotation injuries
24
Q

What is the Weber Classification System?

A

A classifications system for ankle joint fractures.

25
Q

What type of fractures can affect the talus?

A
  • chip/avulsion
  • talar neck
  • taller body
  • talar dome
  • posterolateral process
  • lateral process
  • talar head
26
Q

What can complicated talar fractures?

A

Avascular necrosis as there is no nutrient artery within the talus.

27
Q

What are the complications of calcaneal fractures?

A

Possible permanent disability, residual pain and delayed return to normal function.

28
Q

What are the most common forefoot fractures?

A

Digital #’s.

29
Q

What happens if digital fractures are inadequately treated?

A
  • haelomata
  • contracted digits
  • transverse plane deformities
  • metatarsalgia
30
Q

What is the cause of a stress fracture?

A

Generally overuse or pathological concerns.

31
Q

What are the symptoms of stress fracture?

A

insidious onset, painful over time, decreases with rest

32
Q

What bones in the foot are most commonly affected by stress fracture?

A

Navicular and metatarsals
