Ball- Heads

Category: Permedica Orthopedics

INTENDED PURPOSE:


Ceramic and Metal BALL HEADS are intended intended for use in Total or partial Hip Replacement procedures in combination with a femoral stem providing 12/14 morse-taper, coupled with a bi-articular head or an acetabular cup and related UHMWPE insert.


MATERIALS:

                BIOLOX® delta: Mix of Alluminium, Zirconia and other oxydes (Al₂O₃ + ZrO₂)- ISO6474/2.

                PM734: Highly nitrogenized Stainless Steel forged alloy- ISO5832/9.

                PM1: Stainless Steel alloy - ISO5832/1.

                CrCo: Cobalt Chromium Molibdenum forged alloy - ISO5832/12.




Product Information


      BIOLOX delta

        Ceramic Ball Heads



4 diameters


28-32-36-40mm


Sleeve Taper 12/14 (top angle 5°42'30")

BIOLOX® delta*   OPTION sleeved ceramic heads are conceived for revision cases when retaining a well-fixed femoral stem with minor damages on the taper surface. The adapter sleeve allows to create a pristine taper interface for the ceramic head before its placement on a stem which remains in situ.


        PM734 / CrCo

           Metal Ball Heads

4 diameters


28-28-32-36mm


Taper  12/14 (top angle 5°42'30")

METAL articular heads are made of special Pm734 highly nitrogenized stainless steel forged alloy or CrCoMo forged alloy.

Each single head is severely controlled to ensure perfect and safe coupling onto the stem taper. Grinding process guarantees perfect sphericity and low roughness values.



 ECCENTRIC

  Metal Ball Heads


2 diameters


28-32mm


Taper 12/14 (top angle 5°42'30")


ECCENTRIC articular heads are made of special PM734 highly nitrogenized stainless steel forged alloy.
The taper axis is 7° angled to allow correction of varus, valgus, antiversion and retroversion by rotating the articular head on the stem taper.
