As returned the bushings are damaged, the inner pin fractured at its tines and the outer pin is worn.The device part and lot numbers are unknown; therefore, the devices could not be dimensionally inspected to their known print specifications.Additionally due to lack of part and lot numbers, neither device history records nor complaint history could be reviewed.The device was used for treatment.Failures of this type were investigated in a previous corrective and preventive action (capa).As a result of this capa, the design of the inner pin was modified in 2010 to increase the performance of the pins.Based on design of the returned inner pin, it was produced prior to design modification.
