Utility of point-of-care musculoskeletal ultrasound in the evaluation of emergency department musculoskeletal pathology

BACKGROUND: To evaluate the utilization of point-of-care ultrasound(POCUS) for the assessment of emergency department(ED) patients with musculoskeletal symptoms and the impact of musculoskeletal POCUS on medical decision-making and patient management in the ED.METHODS: This was a retrospective review of ED patients presenting with musculoskeletal symptoms who received a POCUS over a 3.5-year period. An ED POCUS database was reviewed for musculoskeletal POCUS examinations used for medical decision-making. Electronic medical records were then reviewed for demographic characteristics, history, physical examination findings, ED course, additional imaging studies, and impact of musculoskeletal POCUS on patient management in ED. RESULTS: A total of 264 subjects(92 females, 172 males) and 292 musculoskeletal POCUS examinations were included in the fi nal analysis. Most common symptomatic sites were knee(31.8%) and ankle(16.3%). Joint effusion was the most common fi nding on musculoskeletal POCUS, noted in 33.7% of the patients, and subcutaneous edema/cobblestoning was found in 10.2% of the patients. Muscle or tendon rupture was found in 2.3% of the patients, and 1.9% of the patients had joint dislocation. Bursitis or bursa fluid was found in 3.4% of patients, and tendonitis/tendinopathy was found in 2.3%. Twenty percent of them were ultrasound-guided musculoskeletal procedures, and most of them(73.3%) were arthrocentesis. Of the included studies, all except three either changed or helped guide patient management as documented in the patients’ medical records.CONCLUSION: Our study fi ndings illustrate the utility of POCUS in the evaluation of a variety of musculoskeletal pathologies in the ED.
