RATIONALEX1.1 The primary reasons for this specification are:X1.1.1 To characterize fixation pins and wires used in thetreatment of fractures or disease of the skeletal system

19、.X1.1.2 To incorporate fixation pinsKnowles and Hagietypes (Specification F368).X1.1.3 To specify marking nomenclature.X1.1.4 To add performance requirements in accordancewith Performance Sections request.X1.1.5 To add packaging and labeling.X1.1.6 To remove the dimensions on the Crowe since thedime

20、nsions are not essential.X1.1.7 Specific surface finish was considered, however, notincluded, since test data to confirm what the requirementshould be or what effect it has upon performance were notavailable.X1.2 Designs listed enable the surgeon to select from avariety of fixation pins and wires.X1
