Roof reinforcement ring

In cooperation with Prof. Maurice E. Müller, Mathys developed and produced the M.E. Müller Ring. Since 1996, Mathys has sold this roof reinforcement ring under its own name (CCE). The M.E. Müller Ring has been in clinical use since 1977.

The CCE roof reinforcement ring is made of Titanium and has a rough-blasted surface. In combination with the cemented CCB cup it is used for the treatment of patients with impaired bone substance and/or partial acetabular defects in primary and revision surgery, as long as primary stability can be achieved.

The CCE roof reinforcement ring is press-fitted into the acetabulum and additionally secured against the acetabular roof with 2–5 cancellous screws.1 The screws become locked by the cementing of the CCB cup into the ring.2

  • Available in titanium
  • Portfolio available in sizes 42–58
  • No implant-specific instruments needed
  • The CCE roof reinforcement ring allows positioning of the cemented CCB cup independently of the position of the roof reinforcement ring to reconstruct the individual anatomical situation of the patient3
  • A recess at the pole allows introduction of bone grafts or bone substitute material based on the Müller philosophy4
