Total Shoulder ArthroplastyNCT02143245
Diagnostic Accuracy of Synovial Biopsy for Implant-Related Shoulder Infections
A study testing Synovial Biopsy and Open Tissue Biopsy in people with Total Shoulder Arthroplasty, run by Ottawa Hospital Research Institute at 4 sites in Canada.
Trial summary
The purpose of this study is to determine the efficacy of retrieving tissue samples via an x-ray guided needle that is inserted into the infected tissue in the shoulder. The procedure using the guided needle is called a synovial biopsy versus an open tissue biopsy, which is done at the time of surgery. Read more about this study

About this study
The purpose of this study is to determine the efficacy of retrieving tissue samples via an x-ray guided needle that is inserted into the infected tissue in the shoulder. The procedure using the guided needle is called a synovial biopsy versus an open tissue biopsy, which is done at the time of surgery. By doing the synovial biopsy prior to a revision surgery, the investigators hope to avoid more invasive intervention if it is not needed. Some patients may appear to have an infection but once the biopsy is taken and the results are read, there may not be an infection and therefore no need for a revision surgery.
Read the detailed description
The primary research objective is to assess the diagnostic accuracy of percutaneous synovial biopsy for detection of implant-related intra-articular shoulder infections (IISI).
The secondary objectives are to document the frequency of pain associated with shoulder synovial biopsy and to determine the correlation and agreement of several indices of infection as a means of providing preliminary evidence toward a clinical decision rule to rule in or rule out the diagnosis of implant-related intra-articular shoulder infection.
The third objective is to determine the rates of (re)infection, functional outcomes, and quality of life, over a two year follow up period following revision surgery.
The fourth objective is to determine whether an association exists between the biopsy location within the joint and relative yield and positive culture rates.
The fifth objective is to identify, develop, and validate tissue-specific biomarkers for the detection of IISI.
It is our hypothesis that synovial biopsy is valid tool for use in the diagnosis of shoulder arthroplasty and fracture implant related infections.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Synovial BiopsyDiagnostic test
Synovial biopsy is a procedure using a guided needle, where 6 to 8 small tissue samples with be extracted from the shoulder using an x-ray guided needle.
Open Tissue BiopsyDiagnostic test
During the standard of care revision surgery, 6 to 8 small tissue samples will be taken in order to test for infection. This is standard of care treatment. As part of this study, an additional 1 to 2 samples of tissue would be taken in order to develop a test to determine more precisely what type of infection there may be.
| Study group | Role | What they receive |
|---|---|---|
| Revision Population | Other | The study population is both men and women who have had previous shoulder surgery with symptoms suggestive of deep infection. These include the presence of pain, stiffness, and radiologic signs of infection including implant lucencies or migration.
Patients in this population will undergo a synovial biopsy, in addition to undergoing an open tissue biopsy at the time of their procedure. Diagnostic accuracy will be compared, and all participants will be tracked over time. Receives: Diagnostic Test: Synovial Biopsy; Diagnostic Test: Open Tissue Biopsy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Synovial Biopsy (test diagnostic) and Open Biopsy (reference standard)
To assess the diagnostic accuracy of percutaneous synovial biopsy (test procedure) for detection of implant-related intraarticular shoulder infections (IISI), in comparison to direct macroscopic synovial biopsy, from either arthroscopic or open procedures (the reference standard).
To address the primary objective, standard diagnostic accuracy statistics (sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio) will be derived, comparing lab results from percutaneous synovial biopsy specimen collection to those of the reference standard test (open/arthroscopic).
Measured: Pre-operatively.
Secondary outcomes (1)
Reported Pain
Using a visual analog scale, participants will rank their pain level 24-hours after the synovial biopsy. 0 indicating no pain, and 10 indicating the worst pain. A higher score indicates a worse outcome.
Measured: 24-hours after biopsy.
