Two-level spontaneous pedicle fracture above a degenerative spondylolisthesis and minimally invasive treatment.

This is a case report and literature review. The objectives of the study are to describe minimally invasive treatment of pedicle fractures, to show contralateral pedicle changes with pedicle fracture treatment, and to review literature on incidence and mechanism of neural arch fractures. After conservative therapy, there are several options for the treatment of pedicle fractures including pediculoplasty, osteosynthesis, or fusion. As patients' age increases, the incidence of pedicle fracture may rise and minimally invasive pedicle screw treatment represents a good motion-preserving option to stabilize without fusion. We report a patient with spontaneous pedicle fractures above a degenerative spondylolisthesis and evidence of contralateral pedicle changes at L2 and L3. After minimally invasive pedicle screw placement, postoperative imaging demonstrated trabeculation across both L2 and L3 fractures with a resolution of contralateral pedicle sclerotic changes and healing of incompletely fracture contralateral pedicle at L2. Pedicle fractures lead to contralateral pedicle sclerotic changes and potential fracture and may cause significant back pain. Stabilization and healing of the neural arch can be achieved with minimally invasive placement of pedicle screws without need for fusion. [ABSTRACT FROM AUTHOR]
