Ultrasonography (US) examination frequently reveals hip joint effusion. However, accurate documentation of its prevalence among children with a diagnosis of TS is scarcely documented in the literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives:<\/jats:title>\n                    <jats:p>The main objective of our study was to evaluate the prevalence of hip joint effusion among children diagnosed with TS in the pediatric emergency department (PED).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A Retrospective chart review of children diagnosed with TS in the PED between 2017 and 2021 who underwent an US examination as part of their evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Overall, 392 children with a mean age of 5 years were included in the study group, of whom hip effusion was demonstrated in 302 (77%) patients.
