Abstract
We report a very rare case of dislocation fracture of the lumbosacral joint. The patient was a 35-year-old male who was injured at work due to forced anteflexion on knee extension.
Although invasive redressment using a posterior approach was performed one week after the injury, redislocation occurred, and laminal wiring and anterior fixation were therefore performed.
The mechanism of injury for this type of fracture may be circumflex force due to strong flexion in the lumbar region.
This fracture is unstable, and anterior and posterior fixation in addition to invasive redressment are required for its treatment.
