BioBall® System
The BioBall® Adapter System is a simple and sophisticated system that allows intra-operative correction of neck length as well as antetorsion/retrotorsion and lateralisation/medialisation on in-situ stems.
Benefits

Minimization of surgical complexity (the stem is retained) and duration.
Possibility to correct retro-/antetorsion and lateralisation/medialization intraoperatively in case of well-fixed in-situ stems.
Possibility to correct the neck length intraoperatively and adjust leg length discrepancy.

About
The BioBall® Adapter, consisting of titanium alloy, allows intra-operative correction of neck length as well as antetorsion/retrotorsion and lateralisation/medialisation on in-situ stems, which might improve gait and might reduce the dislocation risk.
With its offset components and special tapers, the system ought to be available in every hospital as a solution for unexpected situations in primary endoprosthetic care as well.
When it comes to revision surgeries, the BioBall® System offers an important feature: With stems left in-situ with previously used tapers, the BioBall® Adapter compensates mild deformation of the taper surface.
