Model Number	100-016-045
Medical Device Problem Codes	Mechanical Problem (1384); Detachment of Device or Device Component (2907)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	02/25/2021
Type of Reportable Event	Malfunction
Additional Manufacturer Narrative
Mdr required as the failure is a reportable malfunction.Recurrence could cause or contribute to a serious injury because of the possibility of metal edges puncturing the spinal dura.Although it is a rare complication, the dura may get injured or tear during any spinal surgery resulting in the leakage of cerebrospinal fluid (csf), which normally surrounds the brain and spinal cord.This leakage commonly results in severe headaches and nausea, however the effects of a spinal cord injury can range from transient deficits to more serious complications such as paralysis or bladder and bowel dysfunction.Design failure mode and effects analysis is required and has been performed within product risk documentation.Lot history for 4002-6 has been reviewed and no abnormal or nonconforming specifications were observed within the device history record.Receiving activities for lot #4002-6 reviewed include the following.Visual inspection: conforms per (b)(4) and (b)(4).Acceptance activities:conforms per supplier certificate.Dimension inspection:conforms per supplier certificate - functional.Inspection:conforms per fit against pn 100-016-045 lot#1036-3.Anodization: conforms per limit sample.Laser-marking: conforms per (b)(4) and (b)(4).Packaging /labeling: conforms per (b)(4).Simulation of mode of failure determined the failure was not possible when following surgical technique (compressing on both sets of spikes at the same time with the zip compressor large, model 100-303).Deviation from surgical technique (by compressing on a single set of spikes) consistently reproduced the described failure.
Event or Problem Description
On (b)(6) 2021 a physician reported that the zip device derailed from itself ventrally during a lumbar fusion.The physician stated metal edges remained implanted in the patient pointing towards the dura.
