Ultrasonographic approach for a foot ganglion after sewing masks in the COVID-19 pandemic: Blessing in disguise

During the coronavirus disease (COVID-19) pandemic, people volunteered for sewing hand-made face masks. However, sewing-machine operating might be associated with high ergonomic risk and a negative impact on musculoskeletal health. OBJECTIVE AND METHODS: This paper describes an ultrasonographic diagnosis of a foot ganglion - after sewing 300 face masks within two months using a foot-operated sewing machine. RESULTS: The patient significantly improved after an ultrasound-guided aspiration and corticosteroid injection. CONCLUSION: In short, we highlight the importance of ultrasound examination in the management of work (overuse)-related disorders in occupational medicine practice.
