Event Description
|
It was reported that the physician struggled with deploying the indirect decompression (id) spacer during a procedure.The inserter was removed a few times and repositioned to better catch the spinous processes.However, the physician stated that a noise was heard and when the driver was pulled out, the tabs on the driver were broken.The physician was able to remove the broken pieces using a magnet and used a new driver to complete the procedure.After the procedure was completed, it was found that the tabs of the second driver were also broken off.The physician stated that broken pieces of the second driver were left inside the patient.There were no patient complications.

Manufacturer Narrative

The returned driver was analyzed and a visual inspection revealed that the end of the driver was damaged and one of the tips of the driver was completely sheared off.The damage to the driver was sufficient to prevent functional testing.Field return samples were sent for scanning electron microscopy (sem) analysis, material composition, and hardness testing.Analysis results indicate the device issue is associated with presence of excessive hydrogen in the instrument material.A labeling review was performed and it did not reveal any anomalies as the instructions for use (ifu) states to avoid application of excessive stress on instrumentation and do not force deployment or spacer breakage or damage to bony structures may result, as well as advance the dilator assembly manually and with the assistance of a mallet until the distal tip approaches the dorsal aspect of the facet shadow.Finally, insert the driver through the proximal entry point on the inserter and gently rotate until the distal end of the driver has engaged the spacer.Spacer breakage or damage to bony structures are among other risks associated with the procedure.The reported event of the broken driver was confirmed.A visual inspection revealed that the end of the driver was damaged and one of the tips of the driver were completely sheared off.Field return samples were sent for scanning electron microscopy (sem) analysis, material composition, and hardness testing.Analysis results indicate the device issue is associated with presence of excessive hydrogen in the instrument material.Therefore, the probable cause of the broken driver was determined to be due to a manufacturing deficiency.
