Additional Manufacturer Narrative
The mayfield radiolucent skull pins (a2020) was returned for evaluation: device history record (dhr) - the dhr was reviewed and shows no abnormalities related to the reported failure.Failure analysis - investigation of the returned a2020 skull pin found that a large shard of the pin had fractured off.A2020 skull pin fracture can result from excessive bending and shear load on the skull pin.No damage or incident marks were noted on the plastic pin base.Root cause - the complaint is confirmed via inspection of the unit.Probable root cause includes improper or suboptimal seating and placement of the pins resulting in an excessive shear force on the pin.Additionally, the radiolucent pins are fragile and susceptible to damage from rough handling such as dropping.No further investigation is required based on the acceptability of risk and no adverse trends were identified.This will be monitored and trended going forward.At present, we consider this complaint to be closed.
