Dislocation requiring revision in total hip arthroplasty.

H U Cameron, G A Hunter, R P Welsh

    Archives of Orthopaedic and Traumatic Surgery. Archiv Fur Orthopadische Und Unfall-Chirurgie
    |January 1, 1979

    Summary

    Recurrent dislocation is a complication following hip revision surgery. Component malposition is the most frequent cause of early dislocation, with revision surgery yielding suboptimal outcomes.

    What's New In Hip Surgery?

    Canadian family physician Medecin de famille canadien·2011

    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering

    Background:

    • Hip revision surgery aims to restore function and alleviate pain.
    • Recurrent dislocation remains a significant complication, impacting patient outcomes.

    Purpose of the Study:

    • To investigate the incidence and causes of recurrent dislocation after hip revision.
    • To evaluate the effectiveness of revision surgery for recurrent dislocation.

    Main Methods:

    • Retrospective analysis of 141 hip revision cases.
    • Identification of dislocation events and their timing (early vs. late).
    • Assessment of causative factors, particularly component malposition.

    Main Results:

    • Seventeen of 141 hip revisions (12%) were due to recurrent dislocation.
    • Thirteen dislocations occurred early postoperatively; four occurred >2 years after surgery.
    • Component malposition was the primary cause in early dislocations.
    • Revision surgery achieved acceptable results in only 40% of cases.

    Conclusions:

    • Recurrent dislocation is a notable complication of hip revision surgery.
    • Early dislocations are frequently linked to component malposition.
    • Current revision strategies for recurrent dislocation have limited success rates.
