Continuum™ Acetabular System

The power to meet a wide variety of individual patient needs.

Zimmer® Continuum Acetabular System provides highly flexible solutions for orthopedic surgeons who treat a wide range of patients. The system combines the biologic ingrowth of Trabecular Metal ™ Technology with Zimmer advanced bearing options.  With one of the most comprehensive systems, surgeons have the ability to address variations of anatomy and choose the bearing technology that best meets the needs of each patient.

Highly porous Trabecular Metal Material with over eleven years of clinical history

Designed to Provide Initial Stability

.98 Coefficient of friction*

  • Creates an excellent initial scratch fit, reduces micromotion to support better biologic ingrowth
  • This initial stability helps reduce the need for supplemental screws or ancillary fixation

* for non-machined surfaces

Trabecular Metal Characteristics

Up To 80% Porosity

  • Nearly 100% open pore structure and up to 80% porosity
  • Allows for more biologic ingrowth

Trabecular Metal Acetabular Shells Have Over 11 Years of Clinical History1,2

  • Trabecular Metal Implants have over 11 years of clinical history, with more than 75 peer-reviewed journal publications

Power to choose advanced bearing technologies to match patient demands

Longevity® Highly Crosslinked Polyethylene is highly resistant to wear10,11 and aging12-16 with over ten years of clinical history.17

Metasul® Metal-on-Metal Material has a very low wear rate18 with over twenty years of clinical history.18

Secure Liner Locking Mechanism

Longevity Liners

The locking groove design is designed to mate and lock with polyethylene liners.

Hard-Bearing Liners

Metasul Liners are secured by a taper locking mechanism consisting of a circumferential 18° taper around the outside rim of the liner.  These liners are designed with a tapered radius for easier insertion.
