INHANCE™ Shoulder System
The INHANCE™ Shoulder System empowers surgeons to treat a broad range of shoulder replacement cases in less time using fewer interoperative steps and a seamless construct design. INHANCE™ is designed to meet unmet needs in shoulder arthroplasty by addressing critical inefficiencies in intra- and postoperative operations, so surgeons can advance their patient care while reducing cost at the site of care.

Why INHANCE™?
The INHANCE™ Shoulder System offers a simplified surgical technique and optimized instrumentation, which may result in:
Better Efficiency
Reducing the number of trays necessary to do a case may improve intraoperative efficiency and reduce the number of trays needing to be stored, retrieved, and set up.13,14,25
More Consistency
Allows surgical teams and staff to be trained on and become proficient with a single system vs. multiple different systems, which may improve consistency and repeatability.14,26
Lifetime Cost Savings
The INHANCE™ System provides $525 in estimated savings per case through a reduction in Sterilization,*by only requiring two trays regardless of construct.
*Assumes 11 trays (glenoid and humeral) currently used per case and 4 trays used with the INHANCE™ Shoulder System and a cost per tray of $75
TIME-SAVING CONSTRUCTION
Stemless Constructs
Shoulder arthroplasty procedures can be associated with extended surgical duration and blood loss. 8,9,10,11 Studies have also shown that extended surgical duration is associated with a variety of postoperative medical complications and increased use of healthcare resources.10,11
INHANCE™ offers a stemless implant option that addresses these inefficiencies, with key benefits such as:
- Lower operating room times compared to standard stems (up to 25 min lower).9,21,22,23 Shorter operative time may also lower indirect marginal costs due to increased throughput and efficiency.
- Up to 16% lower estimated blood loss with stemless compared to standard stems, which may reduce the need for costly transfusions.22,23
A NEXT-GENERATION GLENOID
INHANCE™ Anatomic Glenoid
The INHANCE™ Anatomic Glenoid is one of the key features that make the INHANCE™ system leap forward in shoulder replacement technology, with features and benefits like:
-
Stability while removing 45% less bone than a traditional pegged glenoid and 35% less bone than an inset glenoid.3
-
In testing, accelerated aged INHANCE™ Anatomic Glenoids demonstrated a 780% reduction in wear particles compared to unaged conventional polyethylene glenoids after 5 million cycles.4
-
Mechanical testing of the INHANCE™ Anatomic Glenoid demonstrated less displacement than a market-leading pegged hybrid glenoid.5
+ +
Thin-finned peripheral Anchor Ring that is designed to achieve immediate fixation and peripheral stability similar to inset glenoids.
+ +
Finned Anchor Peg central post designed for biologic fixation.
+ +
The INHANCE™ Shoulder System Anatomic Glenoids are offered in five sizes that are compatible with all INHANCE™ Shoulder System Anatomic Humeral Heads.
+ +
Self-Centering design for anatomic translation.
+ +
Crosslinked utilizing Vitamin E to increase oxidation resistance.2
SURGICAL ACCURACY & EFFICIENCY
ONE STEP PREP™
Simplify the implant process and reduce the number of steps with our ONE STEP PREP™ Glenoid process.
ONE STEP PREP™ Glenoid reduces the total number of surgical steps by up to 59% over traditional pegged glenoids.7
The INHANCE™ Shoulder System circular glenoid shape is designed to simplify implant insertion with an attached inserter, compared to an oval or pear-shaped glenoid.
ONE STEP PREP™ Reamers prepare all glenoid features on the same axis, in contrast to other systems which require sequential step preparation.
