title: [Long-term results of single stem silastic implants in the metatarsophalangeal joint].
abstract: OBJECTIVE
  Long-term results of single stemmed silicone prostheses.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  By reason of the high rate of failure of the implant, we have abandoned this procedure.
