The Christiansen hip prosthesis preliminary results.

The combined endo- and total hip prosthesis of Christiansen is described. In this prosthesis an articular connection, or trunnion bearing, is introduced between the head and stem components in order to reduce friction at the acetabular joint. The stem portions of both prostheses are identical. The endoprosthesis was inserted in 50 patients, who were followed-up during one year. The results were according to the classification of Love (Surg. Clin. N. Amer., 1963, 43, p. 1217): excellent in 60%, good in 22%, and poor in 18% of cases. In addition some results from other Norwegian hospitals were presented.
