Survival of hemiarthroplasties after cervical hip fractures
The survivorship of 434 hemiarthroplasties implanted between 1969 and 1982 was calculated from modified life tables. Nine years after surgery 15% of the endoprostheses had been exchanged to a total hip prosthesis. The risk for such a revision was greatest during the first years. Only one of 51 cemented endoprostheses had to be exchanged. The age of the patients at the hemiarthroplasty averaged 76 years. Within 5 years after surgery 50% of the patients were deceased.
