It was reported that during the second part of the superion indirect decompression system implant procedure while placing the second device at l3-4 it was noticed that alignment seemed off when the device was deployed.The device at the l3-l4 was removed and l4 spinous process fracture was observed, the previously successfully implanted device at l4-l5 was also removed.It is unclear whether the fracture was caused by the implant or if it was pre-existing, however the patient does have osteoporosis.An magnetic resonance imaging (mri) was performed and it was noted that the most caudal fully segmented lumbar vertebra is l5.It is unclear which device was used at what level.This is the report for the first device.
