Summary
A rare type I odontoid fracture occurred after a motorcycle accident, causing neurological deficits. Conservative treatment was initiated, highlighting the injury mechanism and potential for cervical root avulsion.
Area of Science:
- Trauma surgery
- Neurosurgery
- Orthopedic surgery
Background:
- Motorcycle accidents can lead to severe head and neck trauma.
- Odontoid fractures, particularly Type I, are uncommon injuries.
- Cervical root avulsion can result from significant neck trauma.
Observation:
- A 17-year-old male presented with somnolence, nuchal tenderness, and left upper extremity monoplegia post-accident.
- Three-dimensional computed tomography confirmed a Type I odontoid fracture.
- Neurological deficits suggested associated cervical root avulsion injuries.
Findings:
- Type I odontoid fracture is a rare injury.
- Coronal distraction of the head and neck is a potential cause.
- Conservative management was pursued for the odontoid fracture.
Implications:
- This case underscores the importance of recognizing rare odontoid fracture patterns.
- Understanding the mechanism of coronal distraction is crucial for injury prevention.
- Sequelae from cervical root avulsion highlight the potential for long-term neurological deficits.
