Haskel JD, Kaplan DJ, Fried JW, et al. - The present study was conducted to ascertain whether any relationship exists between physical examination and/or imaging findings [ultrasound (US) and magnetic resonance imaging (MRI)] and IPT in order to define the reliability of these diagnostic modalities. Between 2014 and 2019, researchers retrospectively examined individuals who had undergone US-guided iliopsoas tendon sheath injection (of lidocaine and a corticosteroid agent) as well as MRI performed within one year of injection. They queried demographic data, response to physical exam maneuvers, and response to injection from patient records. Via 2 independent musculoskeletal-trained radiologists, US and MRIs were reviewed. The analysis included a total of 63 individuals, with mean age 52.3 years +/- 17.3, with average BMI 27.4 +/- 4.3, and average follow-up was 33.6 months +/- 20.6. The data exhibited that in patients with suspected IPT, neither physical examination, nor US, nor MRI findings were correlated with a positive response to peritendinous iliopsoas corticosteroid injections.
