To report patient outcomes up to 1 month after fluoroscopy-guided iliopsoas bursa injection for suspected iliopsoas tendinopathy.


Thirty-nine consecutive patients (mean age 45 years; 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 1 day, 1 week, and 1 month 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 15 min, 1 day, 1 week, and 1 month post-injection and compared to baseline.


Forty-nine per cent of patients reported clinically relevant ‘improvement’ (PGIC) 1 month post-injection. Mean NRS score prior to injection was 5.9 ± 2.1. Mean NRS scores after 15 min (3.6 ± 2.7), 1 day (4.4 ± 2.7), 1 week (3.4 ± 1.9), and 1 month (3.5 ± 2.5) were statistically significantly lower (p ≤ 0.001) compared to baseline. Reduction of NRS ≥50 % after 15 min was achieved in 49 % (56 % of those unimproved at 1 month).


Fluoroscopy-guided iliopsoas bursa injection leads to a relevant ‘improvement’ at 1 month or significant pain reduction after 15 min 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.
