The Souter elbow prosthesis showed poor outcomes in a five-year follow-up study, with high rates of loosening and revision surgery. Re-operation results were unsatisfactory, leading to the discontinuation of this prosthesis.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science

Background:

  • Severe elbow pain and dysfunction often necessitate prosthetic replacement.
  • Rheumatoid arthritis is a common indication for elbow arthroplasty.

Purpose of the Study:

  • To evaluate the long-term outcomes of Souter elbow prosthesis replacement.
  • To assess the efficacy and complications associated with this specific prosthetic device.

Main Methods:

  • A follow-up study of 27 patients (30 elbows) who received Souter elbow prostheses.
  • Radiological and clinical assessments were performed at a mean follow-up of five years.
  • Analysis of revision surgeries and their indications.

Main Results:

  • 19 elbows (26%) showed deterioration; 80% of humerus components had radiological loosening.

Related Experiment Videos

  • Over half of humerus components showed cranial migration; re-operation outcomes were poor.
  • Fractures occurred during surgery, necessitating further interventions.

    • Conclusions:

    • The Souter elbow prosthesis demonstrated unsatisfactory long-term results and a high complication rate.
    • Radiological loosening significantly impacted patient prognosis, making re-operation ineffective.
    • Due to poor outcomes, the Souter elbow prosthesis is no longer utilized at the institution.
