Key Points

  • The aim is to highlight a case of intra-prosthetic dislocation during reduction of a hip replacement.
  • A case study of an 89-year-old female post-artificial hip joint replacement.
  • Reduction attempts were performed under spinal and general anesthesia with imaging evaluations afterwards.
  • Surgical intervention included a navigated revision surgery after diagnosis of intra-prosthetic dislocation.
  • Successful revision surgery with no further dislocation reported post-operation.
  • Initial reduction efforts did not restore proper alignment as confirmed by imaging studies.
  • Polyethylene bearing was found dislocated at the posterior wall of the acetabulum.
