[Long-term experiences with the "St. Georg" sliding endoprosthesis].

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.
