Summary
This case study details a traumatic bilateral L4-L5 facet dislocation without neurological deficit in a woman following a car accident. Surgical reduction and fusion were successfully performed, highlighting a safe treatment approach for this spinal injury.
Area of Science:
- Spine surgery
- Traumatology
- Orthopedic surgery
Background:
- Traumatic bilateral facet dislocation is a severe spinal injury often associated with neurological deficits.
- Motor vehicle accidents are a common cause of high-energy spinal trauma.
Observation:
- A 47-year-old woman sustained traumatic bilateral L4-L5 facet dislocation after a motor vehicle accident.
- The injury mechanism involved a combination of hyperflexion, distraction, and rotation.
- Notably, the patient presented without any neurological deficit.
Findings:
- Open reduction was effectively achieved by removing disrupted capsular and synovial tissues.
- The surgical approach included posterior interbody and posterolateral fusion with pedicle screw augmentation.
- This combined surgical strategy was deemed safe and effective.
Implications:
- This case demonstrates that traumatic bilateral facet dislocations can occur without neurological compromise.
- The presented surgical technique offers a viable and safe treatment option for such injuries.
- Further research into the biomechanics of spinal trauma may refine management strategies.
