[edit] Discussion of Ankle fracture

[edit] Weber Classification

  • Uses the position of the level of the fibular fracture in its relationship to its height at the ankle joint.

  • Type A: fracture below the ankle joint
  • Type B: fracture at the level of the joint, with the tibiofibular ligaments usually intact
  • Type C: fracture above the joint level which tears the syndesmotic ligaments.

[edit] Lauge-Hansen Classification

  • Uses 2 words descriptors. The first word describes the position of the foot, the second word describes the motion of the foot (talus) with respect to the leg.

  • Supination-Adduction (Weber A)
  • Supination-External rotation (Weber B)
    • Stage 1: the anteroinferior tibiofibular ligament is torn or avulsed
    • Stage 2: the talus displaces and fractures the fibula in an oblique or spiral fracture, starting at the joint.
    • Stage 3: tear of the posteroinferior tibiofibular ligament or fracture posterior malleolus
    • Stage 4: tear of the deltoid ligament or transverse fracture medial malleolus
  • Pronation-Abduction (Weber C)
  • Pronation-External rotation (Weber C)
  • Pronation-Dorsiflexion (Weber C)
