Traumatic atlantoaxial dislocation causing os odontoideum in infants
Spine
|May 1, 1980
Summary
Os odontoideum, a debated spinal condition, may develop post-trauma in infants. This study suggests postnatal fracture of the odontoid process causes this abnormality, potentially leading to severe cord compression.
Area of Science:
- Pediatric Orthopedics
- Spinal Surgery
- Developmental Biology
Background:
- The exact cause of os odontoideum remains unclear, with ongoing debate in the medical community.
- Os odontoideum is a rare developmental anomaly of the upper cervical spine.
Observation:
- Two infant cases of traumatic atlantoaxial dislocation were observed.
- Os odontoideum subsequently developed in both infants following the initial trauma.
Findings:
- The study proposes a novel theory for os odontoideum pathogenesis.
- Postnatal fracture of the odontoid process is hypothesized as the cause of os odontoideum development after trauma.
Implications:
- This finding could reshape the understanding of os odontoideum development.
- Early identification and management of odontoid fractures may prevent os odontoideum and its complications.
- One infant experienced fatal cervical myelopathy due to cord compression, highlighting the severity of potential complications.
