Aim Of The Study:
Long-term results of single stemmed silicone prostheses.
Method:
61 feet were reviewed after a mean follow-up time of 13 years.
Results:
18 implants (29.5%) have been removed, 7 of them in the first year after operation. The often impressive radiologic changes showed no correlation to the subjective results but a correlation to time. 1/3 of the patients were not satisfied with the outcome. An average of 75% of the prosthesis was destroyed after 10 years, 93.5% were loosened.
Conclusion:
By reason of the high rate of failure of the implant, we have abandoned this procedure.
