[The fate of first cup arthroplasty implanted in slovakia.]

Cervenanský in 1948. 17 years after the implantation a gradual onset of limitation in motion began. A painfull contracture developed with a functional shortening of the lower extremity. 50 years after the implantation of the cup arthroplasty a conversion to a cemented total hip prosthesis was successfuly realised with a good result. Key words: cup arthroplasty, prof. Cervenanský, conversion.
