This unique concept offers the surgeon a high measure of intraoperative flexibility.

Incorrect positions of the prosthesis stem and the hip socket can be compensated by the appropriate selection and positioning of the adapter.


Any risk of dislocation after THR is minimized or even prevented entirely. In a large number of clinics this system already accompanies nearly all primary and revision surgeries.  During surgery, standard neck length corrections from S (-3.0 mm) up to 5XL (+21 mm) can be carried out with the BioBallĀ® standard adapters.


In addition, the offset adapters allow for neck length correction, a medialization or lateralization, as well as a correction of retro- or antetorsion.
