[Follow-up of Souter elbow prostheses]
1Kirurgisk avdeling Diakonhjemmets sykehus, Oslo.
Summary
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.
- 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.
