What is the purpose of this trial?

This trial tests the safety and benefits of a new shoulder replacement system called the Zimmer Biomet Shoulder Arthroplasty System. It aims to assist individuals with shoulder joint issues, such as osteoarthritis (joint wear and tear) or rheumatoid arthritis (joint inflammation), who require shoulder replacement surgery. Participants should experience shoulder problems that impact daily life and are not well-managed by other treatments, including significant shoulder pain or a previous unsuccessful shoulder replacement. As an unphased trial, this study provides an opportunity to contribute to important research that could enhance shoulder replacement options for many patients.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

What prior data suggests that the Zimmer Biomet Shoulder Arthroplasty Systems and its instrumentation are safe?

Research has shown that the Zimmer Biomet Shoulder Arthroplasty Systems have been tested for safety and effectiveness in various settings. Specifically, the Sidus® Stem-Free Shoulder was deemed safe in a two-year study conducted in the US and Canada. This study found that patients generally tolerated the treatment well, with no major safety issues reported.

The Comprehensive® Total Shoulder System, designed for adaptability during surgery, has been used successfully in different situations. Early results suggest it is generally well-tolerated by patients, with most experiencing no serious side effects.

These findings provide some confidence in the safety of these systems for shoulder replacement surgeries. However, individual experiences may vary, so discussing any concerns with healthcare professionals is important. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Zimmer Biomet Total Shoulder Arthroplasty System because it offers a new level of precision and customization in shoulder replacement surgeries. Unlike traditional shoulder arthroplasty options, this system is designed with advanced instrumentation that allows for a more tailored fit to each patient's unique anatomy. This could lead to improved joint function and longevity of the implant, reducing the need for additional surgeries down the line. Additionally, the focus on both primary and revision surgeries broadens its applicability, potentially offering better outcomes for a wider range of patients.

What evidence suggests that the Zimmer Biomet Shoulder Arthroplasty Systems are effective for shoulder conditions?

Research has shown that the Zimmer Biomet Shoulder Arthroplasty Systems perform well in shoulder replacement surgeries. In this trial, participants will receive the Zimmer Biomet Total Shoulder Arthroplasty System. Studies have found that the Comprehensive® Total Shoulder System, part of the Zimmer Biomet systems, provides flexibility during surgery and offers options to meet different patient needs. This system is designed to help surgeons operate efficiently, potentially leading to better patient outcomes. Additionally, the Sidus Stem-Free Shoulder System, also part of the Zimmer Biomet systems, has been tested for safety and effectiveness in shoulder replacements. A study involving multiple centers found that this stemless system is a reliable choice for patients with good bone health, particularly those with conditions like osteoarthritis. Overall, these systems have demonstrated clinical benefits and are supported by positive early findings. ^{1 2 4 5 6}

Trial Overview

The trial tests Zimmer Biomet Shoulder Arthroplasty Systems in patients needing new shoulders (primary) or replacements (revision). It checks if these implants are safe and work well by looking at patient scores on standard health scales, X-rays of their shoulders before and after surgery, and tracking any complications.

Published Research Related to This Trial

The UNIVERS 3-D prosthesis significantly improved shoulder function in 74 patients with glenohumeral osteoarthritis, with Constant scores increasing from 34.1 to 68.4 points after an average follow-up of 31.9 months.

The procedure demonstrated a low complication rate of 12.2% and a minimal incidence of radiolucent lines around the prosthesis, indicating both safety and efficacy in reconstructing shoulder anatomy.

In a study of 12 shoulders (11 patients) undergoing reverse shoulder arthroplasty with the custom glenoid vault reconstruction system (VRS), significant improvements were observed in pain and shoulder function scores after an average follow-up of 30 months, indicating its efficacy for complex glenoid deformities.

All implants remained stable without any complications, suggesting that the VRS technique is a safe option for both primary and revision shoulder arthroplasties.

The evolution of shoulder prostheses has led to a decrease in overall complication rates due to improved anatomic design, but there has been an increase in periprosthetic humeral fractures.

The stemless total evolutive shoulder system has been developed to minimize stem-related complications while maintaining the benefits of modern shoulder implants.

Stemless total shoulder arthroplasty (TSA) is a safe and effective option for patients with shoulder issues, preserving bone stock and reducing complications like osteolysis and periprosthetic fractures.

As the incidence of TSA is expected to rise significantly, stemless implants are becoming increasingly popular due to their ability to improve anatomic reconstruction and biomechanical function of the shoulder joint.

The modern cup arthroplasty system offers significant advantages over traditional humeral shaft arthroplasty, including the ability to avoid mandatory humeral head resection and the option to convert to a standard prosthesis if needed.

In a clinical trial involving 14 patients, the cup system demonstrated a notable improvement in shoulder function, with the Constant-Score increasing from an average of 23 to 55 points over a mean follow-up period of 6.1 months.

In a study of 70 patients who received the TESS stemless humeral prosthesis, significant improvements in shoulder mobility were observed, with an average increase of 49 degrees in forward flexion and 20 degrees in external rotation after more than 3 years of follow-up.

Radiographic analysis showed no signs of implant migration or complications, indicating that the stemless design can achieve stable anatomical reconstruction of the proximal humerus, comparable to traditional prosthetic replacements.

Reverse total shoulder arthroplasty (RTSA) has become more popular than total shoulder arthroplasty (TSA) in the U.S., with lower surgical complication rates for patients over 50 years old (2.25% for RTSA vs. 3.94% for TSA).

Patients with a history of tobacco use, depression, and obesity are at higher risk for complications, highlighting the importance of considering these factors when evaluating surgical options.

Shoulder arthroplasty is a versatile surgical option for various conditions, including osteoarthritis, and requires tailored approaches and implants for different indications.

The third generation of shoulder prostheses allows for precise reconstruction of the shoulder joint's anatomy, improving the centering of the glenohumeral joint during implantation.

The custom-made CAD-CAM total shoulder replacement (TSR) significantly reduced pain levels and improved shoulder function in 37 patients with severe glenoid bone loss over a mean follow-up of 5 years, demonstrating its efficacy as a treatment option.

Despite a 16% revision rate due to complications like glenoid loosening and dislocation, the CAD-CAM TSR provided substantial clinical benefits, making it a reliable alternative for patients not suitable for standard shoulder implants.
