Study Notes

Course Overview

Introduction to INHANCE™ Reverse Glenoid and Reverse Humeral implants.
Duration of the course is 30 minutes with audio guidance.
Includes knowledge check for assessment purposes.
Important: Refer to device instructions for indications, contraindications, side effects, warnings, and precautions.

System Introduction

Overview of the INHANCE™ Reverse Shoulder System and its relevance in shoulder surgery.
Focus on Reverse Total Shoulder Arthroplasty (RSA) which reverses the anatomical structure of the shoulder joint.
RSA attaches a metal ball to the glenoid and creates a socket at the humerus, changing shoulder mechanics to favor the deltoid muscle.
Primarily used for patients with irreparable rotator cuff tears or severe cuff tear arthropathy.

Market Growth and Importance

Significant projected increase (~235%) in shoulder arthroplasty procedures from 2017 to 2025.
Expected growth of shoulder arthroplasty to outpace total hip and knee arthroplasties.

Key Selling Features

Utilizes the latest technology and clinical research for optimal results.
Aligns surgical practice with minimally invasive treatment options.
ONE STEP PREP for glenoid preparation, allowing shared footprint and common prep for both anatomical and reverse glenoids.
Streamlined surgical technique requiring only two instrument trays, regardless of construct.
Onlay conversion and inlay kinematics simplify procedures.

Surgical Technique

Step-by-step guide for the surgical implantation of the INHANCE™ Reverse Shoulder System.
Identification of required instrumentation for effective implantation.
Considerations for revision surgeries.

Case Studies and Outcomes

Review of case studies showcasing clinical outcomes associated with the INHANCE™ Reverse Shoulder System.
Summary of critical takeaways for future practices.

Certification

Certification quiz to validate understanding and knowledge gained from the course content.

Cost Saving Opportunities

Significant cost savings can arise from reduced operating room time and lower intra- and post-operative complications.
Surgeons can optimize construct selection during surgery, enhancing efficiency without needing backup instruments.
Fewer surgical trays needed, simplified techniques, and reduced time in the operating room contribute to cost efficiency.

Surgical Efficiency

Common preparation for both stemless and stemmed constructs allows intraoperative conversions without backup systems.
Stemless-first approach is intended to enhance efficiency, reducing the number of trays that need to be stored and setup.

Benefits of Inlay Kinematics

Inlay designs minimize scapular notching and fractures compared to onlay designs.
Systems with inlay kinematics show a fracture rate of 4.7%, compared to 11.9% in onlay systems (p=0.043).
Higher rates of return to activity in patients without fractures (92.1% vs. 71.4%).

INHANCE™ Reverse Shoulder System Features

Developed based on the latest technology and clinical evidence.
Focuses on minimally invasive treatment options aligned with surgeon needs.
ONE STEP PREP for glenoid preparation streamlines procedures.
Shared footprint for anatomic and reverse glenoids, allowing for fewer instrument types.

Instrumentation and Surgical Technique

Efficient instrumentation requires only two trays regardless of construct type.
Simplified conversion process between onlay and inlay kinematics makes procedures more straightforward.

Clinical Context of Reverse Shoulder Arthroplasty (RSA)

RSA reverses the ball-and-socket structure of the shoulder, allowing a metal ball on the glenoid and a socket on the humerus.
This alteration enhances use of the deltoid muscle, which is beneficial for patients with irreparable rotator cuff tears.
RSA is indicated for severe cuff tear arthropathy and complex shoulder fractures.

Growth in Shoulder Arthroplasty

The volume of shoulder arthroplasty procedures is projected to increase by approximately 235% from 2017 to 2025.
