15、redevrForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whi
16、ch a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all m
17、atters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are cir
18、culated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held respon
19、sible for identifying any or all such patent rights. ISO 15142-2 was prepared by Technical Committee ISO/TC 150, Implants for surgery, Subcommittee SC 5, Osteosynthesis and spinal devices. ISO 15142 consists of the following parts, under the general title Implants for surgery Metal intramedullary na
20、iling systems: Part 1: Intramedullary nails Part 2: Locking components Part 3: Connection devices and reamer diameter measurements BSISO151422:2003IS-24151 O2:(3002E) I SO 3002 All irhgts seredevr vIntroduction Intramedullary nailing is a method of fixation for temporary stabilization of long bones
21、with reduced strength due to fractures or disease or both. Medical and engineering considerations influence the design of the different devices and the choice of a device for a particular clinical situation. This part of ISO 15142 addresses the locking components used for lockable metal intramedulla
22、ry nails. Because of the wide variety of the devices, classification of the locking components is provided. Nails are often, but not always, removed when they have completed their intended purpose of temporary stabilization. BSISO151422:2003blank BSISO151422:2003INTENRATIONAL TSANDADR IS-24151 O2:(3

It is applicable to all metal intramedullary fixation devices used for temporary fixation of long bones in the human body, except unlockable nails. 2 Normative references The following referenced documents are indispensable for the a

28、n elements of the appropriate nail EXAMPLE Screw, blade, bolt or cross-arm. ISO 15142-1:2003, 3.13 4 Classification and designation Locking components shall be classified into one of the following: a) bolts/screws; b) wires; BSISO151422:2003IS-24151 O2:(3002E) 2 I SO 3002 All irhgts seredevrc) expan
29、ding elements; d) other (claws, hooks, etc.). 5 Materials Locking components shall be manufactured from the same material as the intramedullary nail, or, if another material or condition or both is chosen, the biocompatibility shall be demonstrated in accordance with ISO 10993. A risk assessment in
30、accordance with ISO 14971-1 shall be performed in order to determine that the level of risk of corrosion is appropriate. If another metal is chosen then the effects of galvanic corrosion should be taken into account. 6 Surface requirements The surface finish shall not adversely affect the biocompati
31、bility of the metal used. The effect of surface finish on biocompatibility shall be considered in the risk analysis of the device (see ISO 14602). NOTE The surface finish of the implant is normally selected so that it will not encourage surface bone ongrowth which might make removal of the implant d
32、ifficult or impossible. 7 Marking The implant shall be marked on its surface in accordance with ISO 14630. In the case of anatomical shaping or orientation (left or right) of the device, there shall be a unique marking to avoid wrong positioning. 8 Product labelling The package shall be labelled in
33、accordance with ISO 14602. The label shall include, as a minimum, specific information such as length and diameter. If the locking component is required to be used with an intramedullary nail of a specific metallic composition, then its metallic composition should be stated. 9 Drive connections for
34、insertion and removal of locking components Screw and bolt locking components should be inserted or removed with screwdrivers in accordance with ISO 8319, using a recess in accordance with ISO 5835. NOTE Many existing locking components are designed to be inserted or removed with screwdrivers in acc
35、ordance with ASTM F116 using recesses in accordance with ASTM F543-02. Drive connections conforming to those standards can also be used.
