Summary
Unilateral lumbosacral facet joint dislocation without fractures is rare. This case highlights cross-sectional imaging findings and surgical correlation for this infrequent spinal injury.
Area of Science:
- Orthopedic Surgery
- Radiology
- Spinal Imaging
Background:
- Unilateral facet joint dislocation in the lumbosacral spine is an uncommon spinal injury.
- This injury is frequently accompanied by fractures at the affected or other lumbar levels.
Observation:
- This report details a rare case of unilateral lumbosacral facet joint dislocation occurring without any associated fractures.
- Computed tomography (CT) and magnetic resonance imaging (MRI) were utilized for diagnostic evaluation.
- Surgical correlation was performed to further understand the injury.
Findings:
- The study presents detailed cross-sectional imaging (CT and MRI) of a unilateral lumbosacral facet joint dislocation without fractures.
- This represents the first documented description of cross-sectional imaging for this specific injury pattern in the published literature.
Implications:
- This case contributes to the understanding of rare spinal trauma.
- Accurate diagnosis through advanced imaging like CT and MRI is crucial for appropriate management of such injuries.
- The findings may aid clinicians in recognizing and treating similar rare presentations of facet joint dislocations.
