Three-dimensional computed tomography in infantile atlantoaxial rotatory fixation
1Institute of Orthopaedics and Traumatology, University of Padua, Italy.
Summary
Three-dimensional CT successfully diagnosed rotatory fixation of the atlantoaxial joint in a child with persistent torticollis. This imaging technique guided successful treatment, even in a delayed presentation.
Area of Science:
- Orthopedics
- Radiology
- Pediatric Imaging
Background:
- Acute torticollis can lead to persistent atlantoaxial joint rotatory fixation.
- Delayed diagnosis and treatment of torticollis can complicate management.
Observation:
- A 9-year-old girl presented with fixed head rotation 3.5 months after acute torticollis.
- Three-dimensional computed tomography (3-D CT) was utilized to assess the atlantoaxial joint.
Findings:
- 3-D CT provided clear anatomical visualization of the rotatory fixation.
- The imaging precisely identified the site, extent, and direction of the type-I rotatory fixation (Fielding and Hawkins 1977).
Implications:
- 3-D CT reconstructions are valuable for guiding therapeutic manipulation in complex cases.
- Successful manipulation was achieved despite the delayed presentation, highlighting the utility of advanced imaging.
