Summary
This study details a rare lumbosacral fracture-dislocation, specifically unilateral traumatic L5-S1 dislocation. Surgical intervention successfully restored stability and achieved solid fusion of the lumbosacral junction.
Area of Science:
- Orthopedic Surgery
- Spinal Trauma
- Radiology
Background:
- Lumbosacral fracture-dislocation is an exceptionally rare spinal injury.
- Fewer than 73 cases are documented in English medical literature.
- This case highlights a unilateral traumatic L5-S1 dislocation with posterior ligamentous complex disruption.
Observation:
- A patient presented with a unilateral traumatic L5-S1 dislocation.
- Severe disruption of the posterior ligamentous complex was noted.
- Imaging findings were crucial for diagnosis and surgical planning.
Findings:
- The patient underwent open reduction and stabilization of L4-S1 vertebrae.
- A posterior instrumentation system was employed for internal fixation.
- Post-traumatic ligamentous insufficiency necessitates open reduction and internal fixation to prevent abnormal motion.
Implications:
- Operative treatment resulted in solid arthrodesis and restored lumbosacral junction stability.
- Excellent follow-up results were achieved.
- This case contributes to understanding and managing rare lumbosacral junction injuries.
