Comprehensive® Reverse Shoulder System

Restoring Function One Patient at a Time


The Comprehensive® Reverse Shoulder System minimises the potential challenges of removing a well-fixed humeral stem by allowing conversion to a reverse shoulder using any of the existing Comprehensive Shoulder Stems.

Comprehensive Shoulder Stems:

  • Use the same Comprehensive platform stems (micro, mini, standard, fracture, and revision)
  • Can be used as primary reverse or conversion
  • Can be used in cemented or uncemented applications
  • Incorporate RingLoc® ArComXL® and E1® technologies into the design of the humeral tray and bearing
  • Come with PPS® Porous Plasma Spray Coating proximally to enhance biologic fixation (MacroBond® coating on fracture stem)
  • 45°/135° neck-shaft angle
  • Available in 69 stem sizes

Offering intra-operative flexibility, the Comprehensive Reverse Shoulder System provides a complete, seamless system based on the Comprehensive Shoulder platform.

Recognising the limitations of some reverse shoulders, innovation was engineered into each component of the Comprehensive® Reverse Shoulder System. Zimmer Biomet’s exclusive RingLoc® ArComXL® and E1® technologies have been incorporated into the design of the humeral tray and bearing. This provides a true locking mechanism and also minimises the potential for wear and oxidative degradation.1–8


Humeral Trays

  • Exclusive RingLoc® technology offers a true locking mechanism between the humeral tray and bearing
  • RingLoc technology allows for removal and exchange of the bearing without disruption of the humeral tray or stem
  • Available in standard, +5mm and +10mm
  • 6 suture slots provide for additional attachment points in complex fractures or revisions
  • Compatible with all humeral bearings and glenospheres

Humeral Bearings

  • ArComXL® Polyethylene bearing
  • Available in standard, +3mm and +3mm retentive
  • Includes 12° angle, making the neck-shaft angle 33°/147°
  • Anti-rotation tabs


  • Versa-Dial® Glenosphere
    • Infinite offset options between 0.5mm and 4.5mm and can be positioned in any direction*
    • Medialised or lateralised centre of rotation (Standard, +3mm, +6mm)
    • Available in 36mm and 41mm
  • Fixed offset
    • Can be positioned in any direction
    • Medialised or lateralised centre of rotation (Standard and +6mm)

Glenoid Baseplate

  • Modular design allows for proper orientation of peripheral screw holes prior to impaction
  • Low-profile 28mm diameter
  • 4 identical peripheral locking screw holes
  • Central boss provides for potential of increased fixation and resistance to shear forces

Screw Options

  • Modular 6.5mm central screw allows for compression and increased fixation within the glenoid vault
  • Central screws are available in lengths of 20mm–50mm, in 5mm increments
  • 4.75mm fixed angle locking and non-locking screws are available
  • Non-locking peripheral screws provide for 12ºof flexibility

All peripheral screws are available in lengths of 15mm–45mm, in 5mm increments

Surgical Techniques

*Offset range is limited to 1.5 to 3.5mm for 36mm standard glenosphere.
