[Long-term experiences with the "St. Georg" sliding endoprosthesis]
Abstract:
Primary healing, secondary operations necessary and--by means of follow-up examinations-local sequelae were analyzed after implantation of 65 "St. Georg" sliding prostheses; the operations had been performed at least 5 years and on average 77 months previously, in 64 patients. The overall incidence of early complications was 29.2%, the re-arthrotomy quota, leaving the prosthesis in situ 7.7%, and the incidence of loosening of the prostheses 5.5%. Complications and unsatisfactory results were due less to errors during implantation than to faulty indication. Apart from the loosening, it has been demonstrated that sliding surface prostheses provide satisfactory function, even over many years.
Insights
This study analyzed 65 St. Georg sliding prostheses implanted over 5 years ago. Results show satisfactory long-term function, with complications mainly due to incorrect patient selection rather than surgical errors.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Medical device analysis
Background:
- Implantation of sliding surface prostheses is a common orthopedic procedure.
- Long-term outcomes and complication rates require thorough investigation.
- Understanding factors influencing prosthesis success is crucial for patient care.
Purpose of the Study:
- To analyze primary healing, secondary operations, and local sequelae after St. Georg sliding prosthesis implantation.
- To evaluate the long-term functional outcomes and complication incidence.
- To identify the primary causes of complications and unsatisfactory results.
Main Methods:
- Retrospective analysis of 65 St. Georg sliding prostheses.
- Follow-up examinations of 64 patients with a minimum of 5 years post-implantation (average 77 months).
- Assessment of early complications, re-arthrotomy rates, and prosthesis loosening.
Main Results:
- Overall incidence of early complications was 29.2%.
- Re-arthrotomy rate (prosthesis in situ) was 7.7%.
- Incidence of prosthesis loosening was 5.5%.
Conclusions:
- Complications and unsatisfactory results were predominantly linked to faulty indication, not implantation errors.
- St. Georg sliding prostheses demonstrate satisfactory long-term function, excluding loosening.
- Careful patient selection is paramount for successful outcomes with sliding surface prostheses.
