Podcast 722: Lower Extremity Dislocations

Podcast 722: Lower Extremity Dislocations

Contributor: Donald Stader, MD

Educational Pearls:

  • Hip Dislocation
    • Prolonged dislocations can impair blood supply to femoral head
    • Hip dislocation for >6 hours puts patient at high risk for needing a hip replacement in the next two year
  • Knee Dislocation
    • High mechanism
    • Often looks anatomically normal on knee x-ray
    • Vascular injuries of the popliteal artery can cause significant morbidity with some studies suggesting an 80% amputation rate if not treated within 6 hours
  • Ankle Dislocation
    • Common dislocation and often co-occurs with ankle fractures (bimalleolar/trimalleolar)
    • Pressure on the skin from the displaced joint can cause skin tenting, which can lead to skin necrosis
    • Hematoma blocks work well for ankle reductions as an adjunct to or substitute for procedural sedation
