Manufacturer Narrative
Product complaint#: (b)(4). Investigation summary: background: surgeon had to abandon using the trials because of their inability to maintain a straight line on insertion which meant they would flex and often deviate into the spinal canal, which made them unsafe to use. During today¿s case, we had the following issues: there needs to be two insertion devices for the banana cages as if one fails there needs to be a backup. The thread that connects the silver handle to the tightening device for the cage was worn and is a weak point in the insertion device mechanism, this needs to be replaced. The ratcheted or tension attachment for the cage today caused a dangerous misalignment of the banana cage during insertion. Once the cage has been attached to the insertion device in the correct fashion, the surgeon should be able to insert it in a direct line with the instrument. The attachment of the cage was not able to hold the straight alignment, and upon insertion the cage flexed and went into the spinal canal. It is crucial especially for mis that the cage must be able to be inserted in the exact line that the surgeon places it so then once in the correct position in the disc space it can release the tension, move the handle medially, and impact it across the disc space to get in the desired position. This has been used many times with no problems however today showed that even with the slightest amount of wear of the insertion device this creates a very unsafe situation for the patient. This complaint involves eleven (11) devices. Investigation flow: device interaction/functional visual inspection: a viper prime inserter assembly was received at us cq. The assembly was received with all components present, the assembly was complete. There were no obvious visual defects to note. After device disassembly there were no issues identified with the carrier. Functional test: the set-screws of the shaft were loosened, and after a heavy application of force, all components of the device were successfully disassembled. Upon further inspection of the stylet, it was identified that the shaft of the stylet was bent approximately 15 mm from its distal tip. Due to the observed bent condition, this would directly interfere with the inner diameter of the inserter shaft. The geometry of the cannulation of the inserter shaft tightens approximately 100mm from its proximal end, the stylet can travel through the inserter shaft approximately this distance before halting. A heavy force is require to push the stylet through, this is likely due to the geometry interference of the bent stylet versus the wall created by the reduction in cannulation diameter. Upon investigation of the shaft in pi-16026995879030790 there was no dimensional deviations thus the issue was isolated to the stylet. The entire device was able to be correctly re-assembled without the stylet. After final tightening, the completed assembly functioned as intended. All components interacted appropriately. The device was able to be disassembled/reassembled with ease without the stylet, confirming that the issue was isolated to the damaged stylet. The complaint was not confirmed for this device can the complaint be replicated with the returned device(s)? yes, however the issue was isolated to the stylet. The complaint was not confirmed for this device dimensional inspection: dimensional inspection was not performed since there was no defect identified with the device. Document/specification review: 103270032_revb & a conclusion: the overall complaint was not confirmed for the received inserter carrier as no defect was identified with the device. The device successfully assembles with all other received devices besides the stylet. The device disassembly issue was isolated to the stylet. There was no indication that a design or manufacturing issue contributed to the complaint. No design issues were observed during the document/specification review. Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed. Additional monitoring for any potential safety signals will be conducted through complaint trending and other post market safety surveillance activities. A review of the device history record. Device history lot: a review of the receiving inspection (ri) for viper prime inserter carrier was conducted identifying that lot number mf4292703 was released in a single batch. Batch1: lot qty of (b)(4) units were released on 27 mar 2018 with no discrepancies. As a result, the ri identified no issues during the manufacturing, and release of this device that could have contributed to the problem reported by the customer. Device history batch null. Device history review the ri identified no issues during the manufacturing, and release of this device that could have contributed to the problem reported by the customer. Device was used for treatment, not diagnosis. If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
 
Event Description
Device report from synthes reports an event in (b)(6) as follows: it was reported that on (b)(6) 2020, the surgeon had to abandon using the cage, and insertion instruments because of their inability to maintain a straight line. The thread that connected the silver handle to the tightening device for the cage was worn, and was a weak point in the insertion device mechanism. The ratcheted or tension attachment for the cage caused a dangerous misalignment of the banana cage during insertion. Once the cage had been attached to the insertion device in the correct fashion the surgeon should have been able to insert it in a direct line with the instrument. The attachment of the cage was not able to hold the straight alignment, and upon insertion the cage flexed, and went into the spinal canal. It is crucial especially for mis that the cage be able to be inserted in the exact line that the surgeon placed it in. Once in the correct position of the disc space, it can release the tension. The handle can move medially, and can get in the desired position. Wear of the insertion device created an unsafe situation for the patient. There was a surgical delay of sixty (60) minutes. Another cage and inserter were used to complete the procedure. No fragments were generated. The procedure was completed successfully. There were no consequences to the patient. This complaint involve eleven (11) devices. This report involves one (1) tlif-c ei 12mm 8deg 32/12. Concomitant devices reported: implant inserter sh connection (part number tft30101, lot e19di0971, quantity 1), viper prime inserter shaft (part number 286750031, lot unknown, quantity 1), viper prime inserter handle (part number 286750032, lot mf4262402, quantity 1), prime stylet depth adjustor (part number 286750041, lot mf4288302, quantity 1), viper prime insert drive tube (part number 286750034, lot unknown, quantity 1), cage/spacer (part number unknown, lot unknown, quantity 1), handles (part number unknown, lot unknown, quantity 1). This report is 9 of 10 for (b)(4). This (b)(4) captures the 10 out of 11 devices reported/received while (b)(4) captures the other 1 out of 11 devices reported/received.
