On 20 dec 2017 the r&d spine director added the following details: i have discussed the complaint with the sales team and they confirmed that it was a clear surgeon error and there were no problems caused by the implant or instrument.On 22 dec 17 the medical affairs director made the following analysis: after insertion of a l5-s1 interbody cage, the position was tentatively re-adjusted, but the cage fell from the intervertebral space.A new cage was added and the previous one left in the body.The prognosis of this condition is unknown because the position of the first cage is only represented in the 2d images supplied; technically, the permanence of the cage outside of the prescribed position is not a problem.There is no reason to suspect that this adverse event was caused by a faulty device.Batch review performed on 02 january 2018: lot 1620829: (b)(4) items manufactured and released on 01 september 2017.Expiration date: 2022-08-20.No anomalies found related to the issue.To date, (b)(4) items of the same lot have been already sold without any similar reported event.
