  • Joint implant with self-engaging attachment surface
    Patent number: 5755799
    Abstract: The invention shows process steps for the production of attachment faces (3) on metal joint implants, which stand at an angle 0<a<90 degrees against the insertion and attachment direction (40) and comprise cupular shoulder portions (14), which are opened for attachment against the insertion and attachment direction (40). In a first step recesses (6) and shoulders (8) are produced by machining, casting or pressing in the attachment faces (3) of a blank (2) at right angles to the insertion and attachment direction (40). The shoulders (8) have an acute-angled cross section, have a height of between 0.3 and 2 mm and a spacing (31) which corresponds roughly to the twice the height (10).

  • Process for the production of outer attachment faces on joint implants
    Patent number: 5553476
    Abstract: The invention shows process steps for the production of attachment faces (3) on metal joint implants, which stand at an angle 0<.alpha.<90 degrees against the insertion and attachment direction (40) and comprise cupular shoulder portions (14), which are opened for attachment against the insertion and attachment direction (40). In a first step, recesses (6) and shoulders (8) are produced by machining, casting or pressing in the attachment faces (3) of a blank (2) at right angles to the insertion and attachment direction (40). The shoulders (8) have an acute-angled cross section, have a height of between 0.3 and 2 mm and a spacing (31) which corresponds roughly to the twice the height (10).
