Stable:
Unimalleolar: isolated injury. Can remain stable. Stress-view may help
Unstable:
Bimalleolar: both medial and lateral malleolar.
Likely if lateral talar shift is present.
Deltoid ligament might be injured
Trimalleolar: also has a posterior tibia fracture
Masisonneuve fracture: High fibular fracture with syndesmosis disruption.
Stable fractures - immobilization, elevation and ice as tolerated
Cast or boot for 4- 6 weeks
Unstable - reduction, spliting, ORIF
Danis-Weber Classification of the fibula (in isolation)
Type A: stable. Distal to the syndesmosis.
Type B: At the syndesmosis
Undisplaced = stable = NWB in POP
Displaced = unstable
Type C: Above the joint line
Unstable
