[Total hip-joint prosthesis. Critical long-term review of the new McKee Arden CAD stem prosthesis as compared with the usual McKee Arden prosthesis].

The article makes a comparison between the results of total arthroprosthesis operation of the hip with traditional Mckee Arden prosthesis (50 cases operated in the two-year period 1976-77) and those with the new McKee Arden model with C.A.D. stem (52 cases operated in the two-year period 1977-78). All operations were performed at the "G. Pini" Orthopaedic Institute by the same team and with the same surgical technique. The results are based mainly on three parameters (according to McKee): pain, amplitude of movement, and need to use supports. THe Authors conclude by stressing the efficiency of the new model of prosthesis and noting a decrease in intra and post-operative complications.
