Point-of-Care Ultrasound in Greater Trochanteric Pain Syndrome

GTPS, widely known as trochanteric bursitis, encompasses a spectrum of disorders (gluteal
tendinopathy, tears, bursitis, and ITB syndrome) that are difficult to distinguish by
clinical exam alone. Better understanding of US imaging characteristics in relation to
clinical symptoms may be helpful in identifying those patients who would most benefit from
corticosteroid injections and other non-operative treatment options.

Point-of-care musculoskeletal US use has been shown to reduce repeated hospital
appointments, improve accuracy of diagnosis, and provide expedited treatment, thus improving
quality of care in an outpatient musculoskeletal clinic. US assessment is not routinely
included in the management of GTPS patients and ideal imaging modalities are not
established.
