[Late results of implantation of dual head prostheses in hip para-articular fractures].

In the hospital of Aalen through the years 1985 to 1993 a total of 545 patients have been treated by using a "Duokopf"-prosthesis. The average age was 82.6 years. In a retrospective study the mobility and survival rate after surgery of 109 patients, who had undergone such treatment because of a hip fracture, were found out. The survival rate one year after surgery was within the range of the survival rate of the normal population at that age: The evaluation of the mobility one year after implantation with 57% surviving patients, who are able to walk without aid is a good result. None of the patients showed a protrusio acetabuli. Although the evaluation of the presented results is limited, since, due to the high average age, the mortality rate after surgery was extreme, the Duokopf prosthesis has proved to bring up good long term results.
