[Web-based learning in musculoskeletal ultrasound]

Education and training in musculoskeletal ultrasound (MSUS) comprises attendance at theoretical and practical courses and independent study. Web-based learning as a novel teaching method has previously been described. The present study summarizes normal and pathological findings in a web-based approach using widely accepted guidelines. In a prospective study over a period of 3 years normal and pathological images of the musculoskeletal system have been documented and catalogued. Overall 1240 ultrasound images and 183 ultrasound videos were collected. A total of 14.4% were normal and 85.6% were pathological MSUS findings; 61% concerned the upper extremity, while 39% were images and videos of the lower limbs. The most captured conditions included synovitis (33.3%), pathologies of the tendons e.g., tenosynovitis or tendinosis (19.6%) and normal findings (14.4%). The most represented diseases were rheumatoid arthritis (20%), calcium deposition disease (8.2%), gout (7.1%) and osteoarthritis (6.9%). The images and videos were edited and integrated in a web-based tool.
