Comparing two types of reverse shoulder arthroplasty systems for rotator cuff issues

Migration and Functional Outcome of DELTA Xtend Reverse Shoulder Lateralized Glenosphere Line Extension System

Not applicable Interventional Herlev and Gentofte Hospital · NCT05447819

This study is testing two different types of shoulder replacement systems to see which one helps people with severe shoulder problems feel and move better after surgery.

What this trial studies

This clinical trial is a randomized controlled trial that compares the DELTA Xtend Reverse Shoulder System Lateralized Glenosphere Line Extension with the standard DELTA Xtend Reverse Shoulder System. It aims to evaluate the migration and functional outcomes in patients suffering from rotator cuff arthropathy or severe degeneration of the glenohumeral joint. The study will include Danish citizens referred to the orthopedic department at Herlev and Gentofte Hospital, with a total of 122 patients expected to participate. The primary outcome will focus on the magnitude and pattern of glenoid migration post-surgery.

Who should consider this trial

Good fit: Ideal candidates are Danish citizens over 50 years old with rotator cuff arthropathy or severe degeneration of the glenohumeral joint.

Not a fit: Patients under 50 years old, those with cognitive impairments, or those with insufficient glenoid bone stock will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and functional recovery for patients undergoing shoulder arthroplasty.

How similar studies have performed: Other studies have shown promising results with reverse shoulder arthroplasty approaches, indicating potential for success in this trial.

Eligibility criteria

Inclusion Criteria:

1. Rotator cuff arthropathy defined as degeneration of the glenohumeral joint and wear or tear of at least one rotator cuff tendon
2. Degeneration of the glenohumeral joint with intact rotator cuff function but severe posterior wear of the glenoid (\>20 degrees posterior wear)
3. Insufficient effect of non-surgical treatment with symptoms severe enough to justify shoulder arthroplasty.
4. ASA (American Society of Anesthesiology) score 1-3, physically fit for surgery and rehabilitation

Exclusion Criteria:

1. Below 50 years of age
2. Cognitive or linguistic impairment
3. Insufficient glenoid bone-stock
4. Previous fracture in the upper extremities
5. Patients with autoimmune mediated inflammatory arthritis
6. Glenoid border medial to the medial border of the coracoid on a true AP radiograph
