9、ional 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 which a technical committee has bee
10、n 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 matters of electrotechnical stand
11、ardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO8548-4 was prepared by Technical Comm
12、ittee ISO/TC168, Prosthetics and orthotics. ISO8548 consists of the following parts under the general title Prosthetics and orthotics Limb deficiencies: Part 1: Method of describing limb deficiencies present at birth; Part 2: Method of describing lower limb amputation stumps; Part 3: Method of descr
13、ibing upper limb amputation stumps; Part 4: Description of causal conditions leading to amputation; Part 6: Description of condition of patient requiring a prosthesis. Future parts will deal with other descriptions of limb deficiencies. Descriptors: Medicine, orthotics, prosthetic devices, upper lim

15、putation was performed, and on other disabilities and attributes of the patient. Members of clinic teams in different countries develop their own nomenclature to meet their own needs. Hence there is a need for an international system to be developed in order to compare one publication with another a
16、nd one patient with another. The different care groups who would appreciate and use a standardized system of describing the reason for amputation and the general state of the patient include surgeons, other doctors (especially those concerned with rehabilitation), physical and occupational therapist
17、s and prosthetists. Such a system would also be of value to epidemiologists and government health officials. The system proposed has to meet the needs of the different members of the clinic team and to enable the description of the cause of amputation and the underlying condition to be recorded in a
18、 way that can be easily incorporated in reports. This part of ISO8548 deliberately aims at defining the minimum information to be described. It should be feasible for this information to be included in forms designed by the individual institution and be capable of ready adaptation for computer analy
19、sis. 1 Scope This part of ISO8548 establishes a method of describing the causal conditions leading to amputation and the underlying pathology. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO8548. At th
20、e time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO8548 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

24、ave life, relieve pain and improve function or general health. The cause of amputation is described in three ways. Firstly, by the clinical condition or conditions leading to amputation, secondly, by the pathological condition or conditions and thirdly, by the specific disease. NOTEFor example, the
25、actual clinical condition leading to amputation might be pain caused by inadequate vascular perfusion due to atherosclerosis which is the pathological condition. It follows, therefore, that one pathological condition may be associated with more than one clinical condition leading to amputation, e.g.
26、atherosclerosis may lead to amputation for nonviability and for pain. Furthermore, a specific disease may present with more than one pathological condition, e.g.diabetes mellitus presenting with dysvascularity, infection or neurological disorder or a combination of these. The cause of amputation sha
27、ll be described by including the information as shown in 4.2 to 4.4. 4.2 Clinical conditions leading to amputation The clinical conditions leading to amputation are: a) acute life threatening situation; b) nonviability; c) pain; d) severe injury; e) infection; f) ulceration; g) neoplasm; h) neurolog
28、ical disorder or i) deformity. State the clinical conditions leading to amputation.BS ISO 8548-4:1998 2 BSI 05-1999 4.3 Pathological conditions leading to amputation 4.3.1 General The underlying pathological conditions leading to amputation may be: a) trauma; b) dysvascularity; c) infection; d) neur
29、ological disorders; e) neoplasm or f) deformity. State the pathological conditions leading to amputation and the additional information as shown in 4.3.2 to 4.3.7. 4.3.2 Trauma Traumatic agents may be: a) mechanical; b) thermal; c) electrical; d) chemical or e) radioactive. State the agents responsi
30、ble and whether there was a traumatic severance, subsequent amputation for severe damage, or because the predicted functional outcome was poor. 4.3.3 Dysvascularity Dysvascularity may be due to: a) atherosclerosis without diabetes mellitus; b) atherosclerosis with diabetes mellitus; c) acute vascula
31、r incident, or d) other. State the conditions leading to dysvascularity. 4.3.4 Infection Infection may affect: a) soft tissues; b) bone; c) joints. State the tissues affected and if possible whether the infection is acute or chronic in nature. 4.3.5 Neurological disorders Neurological disorders may
32、result from: a) congenital abnormality; b) injury; c) infection; d) systemic disease; or e) other causes. State the cause of the disorder. 4.3.6 Neoplasm Types of neoplasm may include: a) benign tumours; b) malignant primary tumours or c) malignant secondary tumours. State the type of neoplasm. 4.3.
33、7 Deformity State the nature of the deformity and whether it was present at birth or acquired subsequently. 4.4 Specific disease State the specific disease leading to amputation, using International Classification of Diseases (ICD) codes.blankBS ISO 8548-4:1998 BSI 389 Chiswick High Road London W4 4
