Evaluation concluded that the surgeon likely did not distract enough space to accommodate the implant size.Due to the small opening, it is likely that the cage could not easily be inserted and thus, an excessive amount of force was used to try to force the cage into the disc space.Upon impaction, the cage cracked and broke into multiple pieces after several impactions.The damage to the echo cage appears to be due to surgeon error.The surgeon removed the broken cage and was able to insert an identical cage without issue, suggesting he was able to adequately distract the disc space and properly insert the second implant according to the surgical technique guide.The customer complaint log was reviewed for any similar occurrences--no similar complaints found.The surgeons' cases will continued to be monitored for similar issues.Investigation concluded that no further action is required at this time.
