Segmental System

A Step Forward

The Zimmer® Segmental System is designed to address patients with severe bone loss associated with disease, trauma or revision.

Cross-System Capabilities

The ability to interchange with selected components from the NexGen ® Rotating Hinge Knee and MOST Options® System offers significant flexibility for reconstructions.

Unique Trabecular Metal™ Technology  

  • The only salvage system to offer advanced TrabecularMetal™ Technology – The Best Thing Next To Bone.™
  • 75%-80% porosity allows two to three times greater bone ingrowth.2,3

95% Condylar Loading

  • 95% of the load passes through the condyles, similar to the loading pattern of a primary implant.¹
  • Designed to maintain centralized contact throughout the range of motion.

Transitional Articular Surface

A tapered articular surface allows for increased intraoperative options.

  • Permits the use of a smaller tibial component for a given distal femur size.

Strong, One-Piece Hinge-Post

  • Can be used with the Segmental Distal Femur and the existing NexGen Rotating Hinge Knee femur.  
  • To resist subluxation, the mechanism offers a constant “jump height” of at least 40mm.4

Anteversion Alignment Mechanism

An incremental alignment mechanism features tab and pocket adjustment for optimal alignment.
