Comparing biopsy and aspiration for diagnosing joint infections in shoulder and elbow surgeries

A Diagnostic Test Accuracy Study Comparing Biopsy to Aspiration in Shoulder and Elbow Arthroplasty Revision Surgery (BASE Study)

Observational Wrightington, Wigan and Leigh NHS Foundation Trust · NCT06268795

This study is testing whether using a needle to take fluid from the joint or doing a surgical biopsy is better for diagnosing infections in patients having shoulder or elbow surgeries.

What this trial studies

This study aims to evaluate the diagnostic accuracy of percutaneous aspiration versus open biopsy for detecting periprosthetic joint infection (PJI) in patients undergoing revision shoulder and elbow arthroplasty. It will utilize microbiological and histological methods to assess the effectiveness of joint aspiration as a pre-operative diagnostic tool. Given the challenges in diagnosing PJI, the study seeks to optimize the diagnostic pathway by integrating clinical findings, laboratory results, and imaging data. The findings could potentially inform better management strategies for patients facing this severe complication.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are scheduled for revision shoulder or elbow arthroplasty surgery.

Not a fit: Patients who are currently on antibiotic treatment or are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and timely diagnoses of joint infections, improving treatment outcomes for patients.

How similar studies have performed: While studies have shown success in assessing diagnostic accuracy for hip and knee arthroplasties, this approach for shoulder and elbow arthroplasties is novel and untested.
