InSet™ Reverse Shoulder System

Complete System Integration

The InSet™ Reverse Shoulder System is engineered to provide bone sparing implant options that help surgeons achieve desirable ROM enhancing biomechanics on an individualized patient basis.

Shoulder System Integration

One simplified and reproducible surgical technique allows for the transition from anatomic shoulder arthroplasty to reverse arthroplasty at any point in the procedure. The complete set of integrated reverse instrumentation is contained within one complementary sterilization container for intra-operative efficiency while reducing the instrumentation footprint, surgical time, operating room turn over, and instrument sterilization costs while increasing existing sterilization and processing machinery longevity1.

System Overview

The InSet™ Biomechanical Advantage

  • A more “anatomic” reverse shoulder construct that helps surgeons achieve desirable impingement free range of motion and avoid undesirable arm lengthening and overstuffing.
  • The hybrid InSet™ bowl facilitates and combines biomechanical relationships comparable to inlay systems with the ease of use and bone conservation benefits of common on-lay systems.

Twistlock Poly-to-Tray Locking Security

  • A novel reverse Twistlock™ locking mechanism secures the polyethylene liner to the tray and may reduce complications associated with liner disassociation based on strength testing2.
  • The Twistlock™ locking mechanism has been tested and proven to be 68% stronger when compared to a market leading competitive on-lay reverse shoulder2 and may reduce the likelihood of PE disease and the long-term incidence of aseptic loosening3.

No-compromise Fixation

  • Anterior and posterior curved fins facilitate improved fixation that may increase implant survivorship and reduce humeral stress-shielding.
  • Anterior/ Posterior fins preserve bone and provide valuable rotational stability.
  • Patented K-Coat porous coating. A porous coating process that adds multiple layers of asymmetrical titanium particles using a high temperature sintering process to create a rough, porous surface for initial fixation, while promoting bone growth into the device for long-term stability4.

No Compromise Glenoid Options

  • The 24mm diameter STD lateralized baseplate options provide 2.5mm of COR lateralization and help surgeons achieve 100% backside contact in even the most challenging glenoid pathologies.
    • Augmented options include 5°, 10° & 15°

The Power of One

  • One complementary sterilization tray contains all the additional instrumentation needed for implantation of a complete In Set™ reverse stemmed construct and an InSet™ reverse standard or augmented glenoid construct.
    • Reduces operating room instrument footprint.
    • Reduces operating room turn-over times.
    • Reduces sterilization costs.
    • Reduces the potential for tray contamination delays.
