+ It is the type of prosthesis in which the femoral head and neck, or in other words the upper end of the femur is replaced, with the preservation of acetabulum. Bipolar hip prosthesis consists of 3 parts: 1- Femoral Stem 2- Metal Head 3- Bipolar Cup
+ Femoral Stems are designed as cemented and cementless HA-coated. + Cocr and PE material are assembled together forming the Bipolar Cup and motion is provided by insertion of the Metal head into Bipolar Cup with the help of the locking mechanism. + This system is used for cases where total hip replacement is not indicated.
1 STANDARD CEMENTED FEMORAL STEM
+ Manufactured from CoCr and Titanium materials. + The exterior surfaces are manufactured as polished according to the requirements of the system. + It ensures the stabilization of bone through cement. + It has a neck angle of 135 degrees and cone of 12/14 mm. + Available in sterile forms with these sizes:
1 / 2 / 3 / 4 / 5 / 6 / 7 / 8
2 ZWEYMULLER CEMENTLESS FEMORAL STEM
+ Manufactured from CoCr and Titanium materials. +The Ha coating and special angular surfaces ensure bone integration and reduce therisk of rotation, which ensures full stability. + Has a neck angle of 135 degrees and cone of 12/14 mm. + Available in sterile forms with these sizes:
1 / 2 / 3 / 4 / 5 / 6 / 7 / 8
3 CALCAR SUPPORTED FEMORAL STEM
+ Treatment of intertrochanteric fractures. + It is used primarily in femurs with insufficient support from trochanter minor and calcar. + Manufactured from CoCr materialusing precise casting technology. + Available in diameters of 10 / 12 / 14 / 16 / 18 mm + lengths of 250 / 350 / 450 mm. + It has a neck angle of 135 degrees and cone of 12 / 14 mm.
4 METAL HEAD
+ Manufactured from CoCr material with a polished surface. + Interior conic diameter is manufactured in accordance with 12 / 14 mm cone specifications of the femoral stem. It has 5 different sizes to adjust the interior depth size. + Has an exterior diameter of Ø28mm, Ø30mm, Ø32mm and -6 /-3 / 0 /+3 /+6 interior conic diameter sizes.
5 BIPOLAR CUP
+ Cocr material is polished and assembled with PE 1020 material liner with a locking mechanism. + Manufactured in the dimensions:
