Podcast 652: Prosthetic Hip Dislocation

Contributor:  Jared Scott, MD

Educational Pearls:

  • While it is rare to have a native hip dislocation, it is relatively common to dislocate a prosthetic hip
  • The mechanism for dislocation is usually adduction, flexion, and internal rotation the hip which can occur when walking
  • Arthroplasty in the setting of trauma or fracture, posterior approach during surgery, and using a small femoral head increase the likelihood of later dislocation
  • If a patient with a total hip arthroplasty says they were walking and then developed hip pain, do not discount a potential dislocation
