Manufacturer Narrative

Evaluation revealed the supracondylar nail t2 scn and the locking screws to be the primary products.No further associated products were reported.A physical examination could not be carried out as the devices were not received for evaluation.According to information received the supracondylar nail was still implanted whereas the locking screw had been discarded by the customer.A review of the device history records revealed no deviation in the manufacturing process.The devices were documented as faultless prior to distribution.Thus, we excluded deviations in material and manufacturing.In the case presented a patient had been treated with a supracondylar nail t2 scn.During the surgery the attending surgeon diagnosed an insufficient degree of freedom in the patient¿s knee via x-rays while bending.Ct radiographs were taken after the surgery showing the distal locking screw to have gone through the patella causing the limited motion.The distal locking screw was removed, which resolved the limited bending freedom.The received x-ray was forwarded to a consultant hcp for review, who confirmed that the distal locking screw had been inserted into the patellar surface by mistake.Based on the above the event was not linked to a deficiency of the devices, but was rather user related (incorrect implantation/ positioning of the distal locking screw).With available information a deficiency of the devices could not be verified.The file will be closed formally.In case relevant clinical information or the items should become available, we reserve the right to update the investigation and change the root cause.Review of complaint history, capa databases and risk analysis did not identify any discrepancies.There are no open actions in place related to the reported event for the subject products.
