BioBall® Adapter – Standard


The original, proven head 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 fifteen years, it has proven its worth nationally and internationally, and has become the gold standard in endoprosthetic hip revision surgery.
The BioBall® system, which Merete brought onto the market in 1999, 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 components with an existing stem.

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 (LINK to literature) many times over. The risk of dislocation following a hip TEP can be minimised or eliminated.

The system should also be on hand during primary operations to address unexpected situations. BioBall® Offset versions allow medialisation or lateralisation as well as correction of retro- or antetorsion when correcting femoral neck length.

Please use the BioBall® AdapterSelector™ to check cone geometry intraoperatively or identify defects in the cone of the in-situ stem during revision surgery.

BioBall® adapters should only be combined with BioBall® heads.
