BioBall® Duo Head

Bipolar head with pre-assembled BioBall® Metal Head

The BioBall^® Duo Head is a bipolar head with the outer shell, the inlay and the inner head pre-assembled. Good acetabular tissue quality is a prerequisite for bipolar head implantation, as it serves as an articulation partner for the metal cup. Combination with the BioBall^® Adapter enables intraoperative correction of offset, neck length, lateralisation/medialisation and antetorsion/retrotorsion.

BioBall® Adapter Standard can be combined with BioBall® Duo Head - BioBall® System
