Background

  • Most ankle dislocations are associated with a fracture
  • Must rule-out neurovascular compromise and conversion to open fracture
    • Reduce immediately if vascular compromise or skin tenting is present
  • Posterior dislocation is most common
    • Assoc with rupture of tibiofibular ligaments or lateral malleolus fracture

Clinical Features

  • Ankle pain/trauma/deformity

Differential Diagnosis

Other Ankle Injuries

Distal Leg Fracture Types

Foot and Toe Fracture Types

Hindfoot

Midfoot

Forefoot

Evaluation

  • Ankle x-ray

Management

Posterior dislocation [1]

  • Assistant places hands under knee and distal thigh to pull counter traction
  • Hold dorsum of mid foot with one hand and heel with other hand. Pull longidtudinally then anteriorly
  • If no assistant, have patient hang leg over edge of stretcher

Anterior dislocation

  • As above, but dorsiflex foot first to disengage talus
  • Then axial traction while assistant is holding traction on tibia
  • Finally push foot posteriorly while assistant adds pulls anteriorly

Lateral dislocation

  • Plantar flex foot then apply traction with assistant holding counter traction

Post reduction (all)

  • Check pulses after any attempts. If not palpable, consult ortho emergently
    • Document pulse/motor/sensory exam before and after any attempts at reduction
  • Splint in posterior as well as sugar tong splint with foot in 90 degree flexion
    • Flex hip and knee to 90 degrees to relax gastroc/soleus
