Manufacturer Narrative

Event description: it was reported that the patient underwent primary operation with ann nail on (b)(6) 2021.After 7 weeks, the surgeon found the second most proximal screw backed out from the proper position.The surgeon is keeping an eye on the patient condition and no revision has been planned so far.The corelock mechanism was utilized.Review of received data: due diligence: no further due diligence required as all required information to support the conclusion is available or was already requested.No medical data relevant to the case has been received.Product evaluation: no product was returned; therefore, visual and dimensional evaluation could not be performed.Review of product documentation: device purpose: all involved devices are intended for treatment.Product compatibility: the product combination was approved by zimmer biomet.Dhr review: review of the device history records identified no deviations or anomalies during manufacturing.Surgical technique sap: explains that the locking of the corelock is done using the corelock driver with torque limiting handle.Turn slowly clockwise to tighten and engage the corelock mechanism until a click is felt from the torque limiting handle.Conclusion: it was reported that the patient underwent primary operation with ann nail on (b)(6) 2021.After 7 weeks, the surgeon found the second most proximal screw backed out from the proper position.The surgeon is keeping an eye on the patient condition and no revision has been planned so far.The corelock mechanism was utilized.The quality records show that all specified characteristics have met the specifications valid at the time of production.Therefore, the investigation did not identify a nonconformance or a complaint out of box (coob).Neither x-rays, operative notes, office visit notes, nor devices or photos of the devices were received; therefore the condition of the components is unknown.Patient factors that may have affected the performance of the components such as bone quality, activity level, type of activity (low impact vs.High impact), and relevant medical history are unknown.Adherence to rehabilitation protocol is unknown.Based on the investigation it could be assumed that possible contributing factors to the migration of the screw might be multifactorial related to either patient condition and behavior, implantation procedure or design features.If and to what extent any of these aspects may have influenced the backing out of the screw remains unknown.In conclusion, as the cause may be multifactorial an exact root cause could not be identified for the migration of the screw.Further investigation has been initiated in order to determine the need of potential corrective and / or preventive actions.The need for corrective measures is not indicated and zimmer switzerland manufacturing gmbh considers this case as closed.Zimmer biomet¿s reference number of this file is (b)(4).
