Ankle fractures Flashcards
what bones do Ankle fracture involve
(lateral, medial, or posterior) malleolus, with or without disruption to the syndesmosis.
what is the classification used for ankle fractures
Weber classification
Weber classification types
Type A – below the ankle joint – will leave the syndesmosis intact
Type B – at the level of the ankle joint – the syndesmosis will be intact or partially torn
Type C – above the ankle joint – the syndesmosis will be disrupted
what does the ankle mortise include
the joint between the tibia, fibula, talus
M shaped joint
ankle fracture clinical presentations
- ankle pain
- ankle swelling
- ankle deformity
Ankle X-rays
- AP view: dorsi flexion to show talus
- Lat. view
ankle fracture conservative Mx
- Analgesia / sedation
- stat manipulation/reduction
- hold: plaster cast
- repeat X-ray to assess reduction
ankle fracture conservative Mx suitability
- Non-displaced medial malleolus fractures
- Weber A fractures or Weber B fractures without talar shift
- Those unfit for surgical intervention
ankle fracture surgical Mx suitability
- Displaced bimalleolar or trimalleolar fractures
- Weber C fractures
- Weber B fractures with talar shift
- Open fractures
ankle fracture complications
- post-traumatic arthritis
- post surgical infection/DVT/PE
Define Pott’s fracture
Bimalleolar (lat./medial) fracture of the ankle
common causes of Pott’s fracture
traumatic injuries, such as falls, sports-related accidents, or motor vehicle accidents
Pott’s fracture clinical presentations
- sever ankle pain
- bruising
- swelling
- unable to weight bear
Ottawa rules of the ankle
- Bone tenderness at the posterior edge or tip of the lateral malleolus or
- Bone tenderness at the posterior edge or tip of the medial malleolus or
- Inability to bear weight for 4 steps both immediately after the injury and when examining.
