Patient Data
Age: 65 years
Gender: Male
From the case:
Unstable L1 burst fracture
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/72955/annotated_viewer_json?iframe=true\u0026lang=us"}
The L1 vertebra is wedge-shaped with the anterior outline appearing ill-defined, suggesting acute compression. Retropulsion can also be observed. The involvement of the spinous process is more subtle, yet clearly visible as a broad lucency (see annotated image).
From the case:
Unstable L1 burst fracture
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/72956/annotated_viewer_json?iframe=true\u0026lang=us"}
A comminuted burst fracture is visible, which involves all three columns. The retropulsion is compressing the spinal cord while a traumatic left foraminal stenosis can also be discerned.
From the case:
Unstable L1 burst fracture
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/72957/annotated_viewer_json?iframe=true\u0026lang=us"}
Key image showing that spinous process involvement can be detected on the x-ray.
Case Discussion
This L1 burst fracture is unstable as all three columns are involved.
