QUEST. 7

She slipped and fell at work

a. Describe the classification used for this injury (3)

b. How would you manage this injury?(2)

P381

A. Two types of classifications can be used for ankle fractures. The Lauge-Hansen classification is based on the adduced mechanism of injury, which is useful in planning how to reduce the fracture. The Danis-Weber classification focuses on the level of the fibular fracture. Fractures distal to tibiofibular joint leaves the syndesmosis intact. Fractures proximal to the tibiofibular joint damages the syndesmosis.

Danis-Weber A: Fibula # below syndesmosis and an oblique # of the medial malleolus

Danis-Weber B: Fibula # at syndesmosis often with a # of the medial malleolus with disruption of the medial ligament

Danis-Weber C: Fibula # above syndesmosis, tibiofibular ligament torn, unstable # subluxation of ankle joint

B. Airway, breathing and circulation resuscitation according to ATLS principles, exclude c-spine injury

Analgesia

Assess and make a note of the neurovascular status of the limb

Reduce dislocation immediately (in casualties) under sedation

Immobilize limb

Elevate limb

Look for other injuries and fractures (esp. of spine, pelvis and hip)

Reassess the neurovascular status of the limb and make a note of it

Refer for definitive treatment
