B2C revision  
  Cemented or cementless revision stem
The B2C Revision is indicated for a reconstruction of the proximal part of the femur when the anatomical condition of the metaphysis is not suitable for a standard stem. In this case, it is necessary to find a diaphyseal support with a long stem fixated either biologically or with cement.

The shape of th stem allows primary stability

  • The proximal part is identical to the standard B2C : metaphysis in "inverted pyramidal" shape, lateral and longitudinal grooves in the coronal plan.

  • The distal part is prolongated through a conical shape on a total length of 200 or 250 mm.

  • Distal section of the stem with 6 faces creating 6 sharp edges for efficient rotational locking.

  • Distal slot in the coronal plan starting from the metaphysis giving elasticity to the stem to match the anterior curve of the femur.

  • Colar allowing either support on the calcar when existing either calcar reconstruction with bone grafts.

  • The rotational stability of the long stem is obtained through a triple locking :

    - locking by a conical shape
    - locking by 6 edges
    - locking by elastic deformation

    Bioactive coating

  • VCoating on the full length of the stem with a plasma spray of 80 of pure hydroxyapatite. Due to its osteoinductive properties, hydroxyapatite allows a bone stock reconstruction of proximal part of the femur and a long term biological fixation of the implants.

    This HA-coated B2C revision stem is indicated only if the primary stability obtained with the trial stem is satisfactory.

  • If it's impossible to get primary stability with the trial stem, the smooth B2C revision stem has to be used and cemented.
