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.
