Pyrocarbon Hemiarthroplasty vs Total Shoulder Arthroplasty for Shoulder Arthritis
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two types of shoulder surgery for individuals with shoulder arthritis. One group will undergo an anatomic total shoulder arthroplasty, which replaces the entire shoulder joint. The other group will receive a hemiarthroplasty with pyrocarbon, replacing only part of the joint with a special material. The researchers aim to determine which surgery provides better outcomes over the next ten years. The trial seeks participants with shoulder arthritis who are considered candidates for either surgery by their surgeon. Participants must speak English and agree to follow the study rules throughout its duration. As an unphased trial, this study allows participants to contribute to valuable research that could enhance future treatment options for shoulder arthritis.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. However, if you have a history of consistent narcotic or chronic oral corticosteroid use, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that hemiarthroplasty with pyrocarbon (HA-PYC) can be a reliable treatment for shoulder arthritis. It aids patients, particularly those under 60, in returning to work and sports. However, it carries a higher likelihood of requiring additional surgery later, approximately 7.6%, compared to other treatments.
For anatomic total shoulder arthroplasty (aTSA), studies indicate it has low rates of additional surgery in the short term and yields positive patient-reported outcomes, even for older individuals with arthritis. Patients often experience significant improvements in satisfaction and range of motion, which persist over time.
Both treatments are generally well-tolerated, but it is important to weigh the benefits and the potential for future surgeries when choosing an option.12345Why are researchers excited about this trial's treatments?
Researchers are excited about hemiarthroplasty with pyrocarbon for shoulder arthritis because it introduces a new material—pyrocarbon—that is durable and biocompatible, meaning it works well with the body and lasts longer. Unlike standard treatments like metal and plastic implants used in total shoulder arthroplasty, pyrocarbon offers a smoother surface that mimics natural cartilage, potentially reducing wear and tear. This could mean less pain and longer-lasting results for patients.
What evidence suggests that this trial's treatments could be effective for shoulder arthritis?
This trial will compare Hemiarthroplasty with Pyrocarbon to Anatomic Total Shoulder Arthroplasty for shoulder arthritis. Studies have shown that a pyrocarbon implant in shoulder surgery can significantly enhance shoulder movement and overall outcomes. The implant is highly durable, with 92% remaining intact without replacement. Pyrocarbon also minimizes damage to the shoulder socket, promoting joint health.
Research indicates that anatomic total shoulder replacement surgery is effective for individuals with shoulder arthritis. It seldom requires further surgeries and receives positive feedback from patients. Many patients report significant improvements in shoulder function and express high satisfaction after this surgery.23678Who Is on the Research Team?
