Summary
Oxygen myelography revealed spinal cord swelling and canal non-visualization in early stages of cervical spinal cord injuries. Late-stage imaging showed cord narrowing and anterior stretching, particularly with bursting fractures.
Area of Science:
- Neurology
- Radiology
- Orthopedic Surgery
Background:
- Cervical spinal cord injuries often result from trauma.
- Fracture-dislocation and bursting fractures are common injury types.
- Understanding imaging findings is crucial for patient management.
Purpose of the Study:
- To evaluate the utility of oxygen myelography in assessing cervical spinal cord injuries.
- To correlate imaging findings with injury type and severity.
Main Methods:
- Oxygen myelography was performed on 15 patients with cervical spinal cord injuries.
- Patients were categorized based on fracture type: fracture-dislocation (7 patients) and bursting fracture (8 patients).
- Early and late myelographic findings were analyzed.
Main Results:
- Early myelography showed cord swelling (3/7) and non-visualization of the spinal canal (6/7).
- Late myelography revealed cord narrowing (5/8) and anterior cord stretching over bony ridges.
- Neurological involvement was more severe in patients with bursting fractures.
Conclusions:
- Oxygen myelography effectively demonstrates spinal cord changes in cervical injuries.
- Imaging findings correlate with fracture type and neurological severity.
- This technique aids in understanding the pathophysiology of cervical spinal cord injuries.
