Conclusion: It is important to be vigilant about pulmonary embolism in children because it is rare but potentially fatal, especially in the presence of risk factors. Early diagnosis and treatment of unstable slipped capital femoral epiphysis are crucial to minimize immobility. Close monitoring of femoral head osteonecrosis is also necessary.enjournal article10.5435/JAAOSGlobal-D-24-0003338996223
