Full Description

1.1This specification provides a characterization of the design and mechanical function of external skeletal fixation devices (ESFDs), test methods for characterization of ESFD mechanical properties, and identifies needs for further development of test methods and performance criteria. The ultimate goal is to develop a specification, which defines performance criteria and methods for measurement of performance-related mechanical characteristics of ESFDs and their fixation to bone. It is not the intention of this specification to define levels of performance or case-specific clinical performance of the devices, as insufficient knowledge is available to predict the consequences of the use of any of these devices in individual patients for specific activities of daily living. Furthermore, it is not the intention of this specification to describe or specify specific designs for ESFDs.

1.2This specification describes ESFDs for surgical fixation of the skeletal system. It provides basic ESFD geometrical definitions, dimensions, classification, and terminology; material specifications; performance definitions; test methods; and characteristics determined to be important to the in-vivo performance of the device.

1.3This specification includes a terminology and classification annex and five standard test method annexes as follows:

1.3.1Classification of External Fixators-Annex A1.

1.3.2Test Method for External Skeletal Fixator Connectors-Annex A2.

1.3.3Test Method for Determining In-Plane Compressive Properties of Circular Ring or Ring Segment Bridge Elements-Annex A3.

1.3.4Test Method for External Skeletal Fixator Joints-Annex A4.

1.3.5Test Method for External Skeletal Fixator Pin Anchorage Elements-Annex A5.

1.3.6Test Method for External Skeletal Fixator Subassemblies-Annex A6.

1.3.7Test Method for External Skeletal Fixator/Constructs Subassemblies-Annex A7.

1.4A rationale is given in Appendix X1.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6Multiple test methods are included in this standard. However, the user is not necessarily obligated to test using all of the described methods. Instead, the user should only select, with justification, test methods that are appropriate for a particular device design. This may be only a subset of the herein described test methods

1.7The following safety hazards caveat pertains only to the test method portions (Annex A2 - Annex A6):

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.9This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
