Management Challenges in Refractory Grisel’s Syndrome Following Kawasaki Disease: The Importance of Timely Orthopedic Intervention and Interdisciplinary Collaboration

Background Grisel’s syndrome is a rare nontraumatic atlantoaxial rotatory fixation often associated with head and neck infections or inflammatory diseases. Its occurrence following Kawasaki disease (KD) is uncommon and rarely necessitates halo‐vest immobilization. Case Presentation We describe the case of a 6‐year‐old girl who developed Grisel’s syndrome after a KD. Despite early diagnosis and conservative management, torticollis persisted, and imaging confirmed atlantoaxial rotatory fixation. Repeated attempts at manual reduction failed, and halo‐vest fixation was required. After immobilization for 2 months, the patient achieved full recovery without neurological or cardiovascular sequelae. Conclusion This case highlights the importance of identifying Grisel’s syndrome as a potential complication of KD. Early imaging and multidisciplinary management are crucial to avoid prolonged morbidities.
