The tip of the cannulated screwdriver shaft t25 was found broken by the surgeon prior to use.The surgeon reported clearly that none of the breakages happened during the surgery and in all cases the device arrived at the surgery already damaged.The surgeon is confident that the damage occurs during transportation to/from the sterilization center (20km kilometers away), during which the instruments are put all together in the trays, with any kind of protection or separation.After these cases, the surgeon is asking the sterilization center to put a protective cap on the instrument to avoid damage.In some cases (unknown which ones), the surgeon used the broken instrument to perform the surgery and in other cases he used a back-up.The surgeon confirmed that no fragment had been left in the patient.

This follow-up is to inform the fda of the new information received on 11 july 2025.A meeting was held with the surgeon, who reported that the breakage did not happen during surgery, and the cause is most likely related to transport conditions to and from the sterilization center.The damage was easily detected by the surgeon prior to use (as the implant must engage on the tip of the instrument).A reoccurrence of the observed failure mode is unlikely to cause death or serious injury.- updated event description (b5).- piece returned on 20 jun 2025.Visual inspection performed by r&d project manager: the distal tip of the screwdriver appeared to be broken.According to feedback from the surgeon, collected during a dedicated web call, the issue was not experienced during surgery, the device was already damaged prior to the procedure.The surgeon suggested that the most likely root cause is transportation to and from the sterilization center, which is external to the hospital.During transport, the instrument is placed in a generic tray together with other devices, without any protective measures.Considering the number of instruments on the market and the low occurrence rate of this event, no immediate actions are necessary.However, r&d is currently evaluating the possibility of a tip design change to increase the instrument wall thickness, without affecting the overall design and functionality.As highlighted by the surgeon, no adverse events occurred to either the patient or the user.Root cause: the breakage of the screwdriver tip most likely occurred during transport to or from the external sterilization center.The device was placed unprotected in a generic tray with other instruments, leading to potential damage before surgical use.
