Abstract Introduction To date, there have been no acceptable and accurate diagnostic criteria or standards of care for the management sacroiliac joint (SIJ) pain. Several studies yielded different contributions clinical presentation, history, physical examination in diagnosis SIJ Our goal this study was to assess sensitivity specificity tests their predictive value accurately diagnosing Methodology Upon enrolling 200 eligible patients with pain as primary diagnosis, they were re‐evaluated verbal rating scale (VRS) scores demographic data obtained. Thereafter, three performed: thigh thrust test, Patrick a modified version Gaenslen test that is referred Mekhail test. Subsequently, taken procedure room undergo injection, which confirmative result ≥50% relief. The physicians performing blinded results 3 performed. Results from incorporated results, we drew statistical medical conclusions determining degree aid We found cumulative effect adding simultaneous increased testing but decreased specificity, generates powerful screening tool. combination demonstrated best accuracy, 94% sensitivity, 17% 81% positive value, 44% negative value. better than other differentiating those non‐SIJ No both significant specificity. Generally, overall any on own did not vary significantly baseline demographics, including pre‐injection score referral diagram. Conclusion In conclusion, our similar previous investigators who plays limited role Specifically, and/or combinations added capacity compared patients’ characteristics predicting response albeit high (94%), making them viable consecutive screening, possibly reducing unnecessary costs injection procedures.
