About this product

Division: Shoulder Reconstruction
Category: Reverse

The DELTA XTEND System is a total semi-constrained shoulder arthroplasty. It reverses the normal relationship between the scapular and humeral components, moving the scapulo-humeral joint center of rotation medially and inferiorly. By doing this, it increases the deltoid lever arm as well as the deltoid tension therefore allowing the muscles of the deltoid group to compensate for rotator cuff deficiency. Each design feature of the Delta XTEND Reverse Shoulder System was chosen to accelerate recovery, optimize function and maximize survivorship.

The DELTA XTEND Shoulder Monobloc Humeral Stem is designed for cemented fixation, while the Modular Humeral Stem is designed for cementless fixation. The glenoid component is cementless with four screws as primary fixation and HA coating for secondary fixation.


Features & Benefits


  Features Benefits
  • Cementless Modular Humeral Implant
  • Fluted stem design based on the GLOBAL® Shoulder Stem Design - positioned in anatomic version for optimal press-fit fixation1
  • Hydroxyapatite (HA) coated titanium alloy for cementless application 2,3
  • Centered and eccentric options to suit anatomy and optimize press-fit fixation
  • 155° neck shaft angle for optimal joint stability4
  • Reduced proximal geometry for bone preservation
  • Cemented Monobloc Humeral Implant
  • Polished Cobalt Chromium alloy for optimised cemented fixation5
  • Reduced proximal geometry for bone preservation
  • Standard and long monobloc stems with suture hole fins and proximal height laser markings on the trial stem for use in proximal bone loss cases
  • Polyethylene Humeral Cups
  • Three cup thicknesses (+3, +6 and +9mm)  to balance soft tissue for optimal deltoid function based on clinical heritage6

  • Glenoid Component
  • Centre of rotation on glenoid bone surface for high resistance to loosening shear forces4
  • Two locking cannulated variable angle screws (compress and lock) and two compression screws with +/- 10 degrees adjustable angulation for metaglene primary fixation, to maximize resistance to loosening shear forces4
  • Curved back and smaller metaglene, for bone preservation and low positioning on the glenoid to reduce risk of scapular bone erosion7
  • Standard (13.5mm) and Long Peg (+10mm and +15mm) Metaglenes allow for primary, revision and bone grafting
  • Hemi-heads available in two diameters and two head heights for easy revision from reverse to hemi-arthroplasty if required
  • Extended articular surface for articulation against acromion
