Summary
This case report details successful surgical management of a rare traumatic L5-S1 spondylolisthesis, emphasizing prompt diagnosis and combined surgical techniques for optimal patient recovery and function.
Area of Science:
- Spine surgery
- Traumatology
- Radiology
Background:
- Traumatic lumbosacral dislocations are rare, with limited documented cases.
- Delayed diagnosis of traumatic L5-S1 spondylolisthesis can occur, leading to persistent neurological deficits.
Observation:
- A 37-year-old man sustained a work-related traumatic lumbosacral dislocation.
- Initial diagnosis was missed; treatment was initiated due to neurological deficits.
Findings:
- Successful surgical reduction, posterior stabilization, and anterior interbody fusion were performed.
- Complete fusion achieved at 1.5-year follow-up, with pain-free ambulation and return to prior work and recreational activities.
- Persistent S1 nerve root deficits (ASIA grade E) were noted.
Implications:
- Computed tomography with biplanar reconstructions is crucial for diagnosing traumatic lumbosacral spondylolisthesis.
- Surgical treatment involving reduction, stabilization, and interbody fusion is the preferred management for this challenging injury pattern.
