BioBall® Adapter Offset

The tried-and-tested head adapter system in 12/14 and 14/16 Offset variants

Today, the modular BioBall^® system is available in practically certified endoprosthetic clinic in Germany. Over the past twenty years, it has established itself in arthroplastic hip revision surgery, proving its worth around the world.

Merete’s titanium adapter compensate misalignment between prosthesis stems and acetabular cups. Offset adapters allow medialisation or lateralisation as well as correction of retro- or antetorsion when correcting femoral neck length.

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 also helps improve the patient’s gait and reduce the risk of dislocation.

Moreover, the system represents a supplementary treatment option for primary operations, in particular for intraoperative correction of misalignments.
