title: [The new rotatory hip-joint endoprosthesis according to the unit construction system after Weber. Experience and results of follow-up checks after five years (author's transl)].
abstract: The new rotatory hip-joint total prosthesis after Weber with rotating metal head and polyethylene socket has yielded a very high percentage of good results to date, according to experience collected in the course of five years and a comprehensive followup study. It was possible to prove that the metallic rotatory joint does not entail any disadvantages, and that it is extremely resistant to wear. The almost complete absence of shaft fractures is remarkable (two cases after 2,500 operations) as well as the low incidence of loosening after primary operation. Complications occur much more frequently following exchange operations. The unit construction principle on which this type of prosthesis is based, offers great advantages in respect of surgical technique. It appears that the rotatory prosthesis is superior to other concepts with regard to wear and to stability of fixation.
