There are still no uniform standards in place for prosthesis stem tapers. Implant manufacturers continue to use tapers designed to their own individual specifications that differ from the others in terms of geometry structure and surface. Neck length sizes (S, M, L, etc.) are not tandardised and may vary significantly from manufacturer to manufacturer.
Besides standard and offset BioBall® Adapters, we also offer BioBall® Adapters for custom tapers, for a wide variety of taper geometries from other manufacturers.
