- No healthy volunteers
- Adult, Older adult
Study population: Patients with substantial glenoid bone loss in the context of severe glenohumeral arthrosis, advanced cuff tear arthropathy or those who have undergone prior shoulder arthroplasty and have or will undergo a reverse shoulder replacement with structural bone graft to address the problem.
Who may be able to join
- Adult patients who have undergone a reverse shoulder arthroplasty with the an extended peg baseplate and structural bone graft (autograft humeral head or allograft femoral head).
- Adult patients who are indicated for a long-pegged baseplate and glenoid bone grafting (autograft humeral head or allograft femoral head) as part of their reverse shoulder arthroplasty in our clinic,
- bone graft is truly structural involving at least 50% of the glenoid baseplate
- may be a primary or a revision surgery
Who cannot join

About this study
Official title: Glenoid Bone Grafting for Reverse Shoulder Arthroplasty: Clinical and Radiographic Outcomes
This study will look at patient radiographic and functional outcomes who have or will undergo a reverse, extended peg, shoulder arthroplasty (replacement) that requires the use of glenoid bone grafting.
Read the detailed description
Glenoid bone loss is a known issue with reverse shoulder implants and can lead to issues with implant fixation and stability over time. To address this issue an extended peg glenoid baseplate is used and area around plate is augmented with bone (auto or allo)graft material to encourage bony callous growth around the implant. This study is to look at this area of concern and determine if glenoid bone loss is occurring in the patients where these measures have been taken to deter its development.

Questions about this trial
What is this clinical trial studying?
An observational study of Osteo Arthritis Shoulders, run by Washington University School of Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Radiographic Outcome (time frame: minimum 1 year post op). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03151109, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Feb 2022.
