Study Design:
This is a retrospective single-patient case report with a literature review.
Objective:
To report on an uncommon injury: traumatic fracture-dislocation of the lumbosacral junction with delayed displacement.
Summary Of Background Data:
Only 31 cases of traumatic fracture-dislocation of the lumbosacral junction were found in the English literature. Only three previous reports refer to this injury occurring with a posterior displacement. This is the first report of this type of injury displacing in a delayed manner.
Methods:
Chart review.
Results:
Open reduction, Arbeitsgemeinschaft fur Osteosynthesefargen instrumentation, and interbody fusion resulted in a satisfactory clinical result with no neurologic impairment.
Conclusions:
The present study reports a very rare injury consisting of traumatic dislocation of the lumbosacral joint, presenting with displacement 2 months after injury. The patient was treated successfully with surgery even though the injury displaced in a delayed fashion.
