Traumatic arthrotomy: A systematic review evaluating diagnostic strategies.

Abstract

The purpose of this study was to systematically review available strategies for diagnosing traumatic arthrotomy. A comprehensive literature search was conducted on October 8th, 2023 using Ovid Medline, Cochrane Central Register of Controlled Trials, Embase, and Embase Classic. Studies were included in the review if they evaluated a diagnostic strategy for traumatic arthrotomy. There were 26 studies included after application of the exclusion criteria. 12 studies investigated traumatic arthrotomy of the knee, 8 of the elbow, 4 of the shoulder, 4 of the wrist, and 5 of the ankle. 23 studies implemented the saline load test as a diagnostic strategy, 7 considered CT scan, 1 study used x-ray, and 1 study used ultrasound. Of the studies that considered saline load tests, 8 of them also used methylene blue. CT scans were found to have 100% sensitivity when diagnosing traumatic arthrotomy of the knee. Saline load test was shown to have 60% to 100% sensitivity when diagnosing traumatic arthrotomies of the elbow. Saline load tests had sensitivities ranging from 75% to 100% when considering a shoulder traumatic arthrotomy. The saline load test was able to diagnose traumatic arthrotomies of the wrist, and ankle with sensitivities up to 100% and 99%, respectively. When considering the infectious risks associated with undiagnosed traumatic arthrotomy, clinicians should seek modalities with the highest diagnostic performance. The saline load test has long been considered the gold standard for diagnosing traumatic arthrotomy, however, imaging modalities hold appeal as a less invasive and technically challenging procedure. Although diagnostic performance is joint-dependent, this review indicates that the saline load test continues to be the most reliable method for diagnosing most traumatic arthrotomies other than the knee.
