The head adapter system as 12/14 and 14/16 Standard variants.
Today, the modular BioBall® System is available in practically every certified endoprosthetic clinic in Germany. Over the past twenty years, it has established itself in endoprosthetic hip revision surgery, proving its worth around the world.
Merete’s BioBall® system allows surgeons to compensate misalignment between prosthesis stems and acetabular cups intraoperatively. When used in revision surgery, the system’s titanium adapters make it possible to use ceramic heads with in situ stems.
The BioBall® Adapter’s variable neck lengths and range of options in terms of both sliding pairs and head sizes allow intraoperative problem-solving, the advantages of which have been described in the literature many times over. The BioBall® Adapter can also be used to help improve patient gait and reduce luxation risk.
Moreover, the system represents a supplementary treatment option for primary operations, in particular for intraoperative correction of misalignments.
In addition to correcting femoral neck length, BioBall® Adapters (TiAl6V4 ELI) allow medialisation or lateralisation as well as correction of retro- or antetorsion.
Adapters are designed to ensure the best possible range of motion (ROM)
