The provided photos show an inner pin that has fractured at its tines.However no devices were returned.Review of the device history records did not find any deviations or anomalies.The devices were used for treatment.No other complaints of any type have been reported for this lot of bushing kits.In the coonrad/ morrey total elbow revision surgical technique it states that, ¿if the size of the previous implant is unknown or uncertain at the time of operation, the humeral yoke gauge may be used intra-operatively to determine the size of implant.This instrument will confirm or determine the size of the well-fixed humeral implant in a patient needing revision or replacement.Once the size is determined, refer to the replacement/revision chart to choose the correct bushing kit for the proper humeral/ulna connection.¿ given that the patient was implanted with a small humerus and an extra small ulna a replacement bushing kit should have been selected per the replacement/revision chart.However a replacement kit was implanted.The subcomponents of the kit are smaller than those in the kit.This incompatible combination would expose the components to greater than anticipated forces, resulting in the reported failure.
