Event or Problem Description
It was reported that during a superion implant procedure, the spacer broke.The physician was implanting in a small tight space in the spinous process.The physician decided to do a sagittal wiggle to loosen things up and the top of the spacer broke off from the inserter.The broken spacer was replaced with a new one.The patient's anatomy was noted to have osteophytes and a thick spinous process.The physician reportedly did not use excessive force during deployment but was not performing the sagittal wiggle technique as he was supposed to.
Additional Manufacturer Narrative
A retroactive review of events within the quality system identified this record as requiring remediation, including reporting and submission of an initial emdr per applicable criteria.Boston scientific has opened a corrective and preventive action (capa 8647) investigation to determine the root cause for why an initial emdr was not previously submitted to the fda in accordance with boston scientific established mdr reporting process and fda adverse event reporting requirements.Information gained through these investigation efforts will be utilized to determine root cause and implement appropriate preventive action(s), as necessary.The device was returned for analysis and the complaint was confirmed.Visual inspection showed that the spindle cap was completely sheared off the implant body.The damage was sufficient to preclude functional testing.The damage to implant indicates failure likely due to a combination of deployment against resistance (e.G., bone) and physician failing to correctly attach the inserter to the spacer.Based on the product analysis, the most probable cause of the complaint is unintended use error caused or contributed to event.Additionally, a labeling review was completed and reveal no anomalies.The instructions for use (ifu) states deployment should not be forced or implant breakage or damage to bony structures may result.Furthermore, it states that if resistance to deployment is encountered, and repositioning of the implant is required, rotate the driver counterclockwise until a positive stop is reached and withdraw dorsally to collapse the cam lobes.
