    Summary
    Objectives: To report patient outcomes up to 1month after fluoroscopy-guided iliopsoas bursa injection for suspected iliopsoas tendinopathy. Methods: Thirty-nine consecutive patients (mean age 45years; range 15-77) who underwent fluoroscopy-guided therapeutic iliopsoas bursa injection using an anterolateral approach and who returned an outcomes questionnaire were prospectively included. The Patients' Global Impression of Change (PGIC) scale was recorded 1day, 1week, and 1month after the injection (primary outcome measure). Patients' subjective pain level data were collected prior to the injection (baseline) using a numeric rating scale (NRS; 0 = no pain; 10 = maximum pain). NRS scores were completed 15min, 1day, 1week, and 1month post-injection and compared to baseline. Results: Forty-nine per cent of patients reported clinically relevant ‘improvement' (PGIC) 1month post-injection. Mean NRS score prior to injection was 5.9 ± 2.1. Mean NRS scores after 15min (3.6 ± 2.7), 1day (4.4 ± 2.7), 1week (3.4 ± 1.9), and 1month (3.5 ± 2.5) were statistically significantly lower (p ≤ 0.001) compared to baseline. Reduction of NRS ≥50% after 15min was achieved in 49% (56% of those unimproved at 1month). Conclusions: Fluoroscopy-guided iliopsoas bursa injection leads to a relevant ‘improvement' at 1month or significant pain reduction after 15min in most patients. Key points : • Fluoroscopy-guided iliopsoas bursa injection is a safe procedure. • Most patients had a diagnostic or therapeutic benefit from the injection. • The anterolateral approach may reduce the risk of damage to the neurovascular bundle. • The procedure is eligible for patients with and without total hip arthroplasty.
