Overview
ISO 8549-4:2020, "Prosthetics and orthotics - Vocabulary - Part 4: Terms relating to limb amputation," defines standardized terminology for describing surgical limb amputations, amputation procedures, and persons who have had an amputation. This second edition (2020) is a vocabulary standard intended to create consistent, internationally accepted language for clinical records, rehabilitation, research, coding and policy. The document contains no normative references and is part of the ISO 8549 prosthetics and orthotics vocabulary series.
Key Topics
This part of ISO 8549 focuses on clear, unambiguous terms used across the prosthetics and orthotics ecosystem:
- General definitions: limb amputation; level of amputation.
- Upper‑limb terms: partial hand (with subtypes such as thumb, phalangeal, metacarpal, carpal), wrist disarticulation, transradial, elbow disarticulation, transhumeral, shoulder disarticulation, scapulothoracic (forequarter).
- Lower‑limb terms: partial foot (phalangeal, metatarsal, tarsal, etc.), ankle disarticulation, transtibial, knee disarticulation, transfemoral, hip disarticulation, transpelvic.
- Amputation procedures: initial amputation, revision amputation, two‑stage amputation, reamputation.
- Person descriptors: amputee, upper/lower limb amputee, bilateral/unilateral/contralateral amputee, triple and quadruple amputee.
- Editorial note: the 2020 edition clarified formatting (e.g., removal of hyphens in anatomical terms) as a minor revision of the 2014 edition.
Applications
ISO 8549-4 is practical for anyone needing precise, standardized language around surgical amputation:
- Clinicians and surgeons: consistent documentation of surgical history and amputation levels in medical records.
- Prosthetists and orthotists: accurate device prescription, fabrication and communication between multidisciplinary teams.
- Rehabilitation teams: standardized reporting of patient status and functional planning.
- Researchers and epidemiologists: harmonized terminology for population studies, outcome measures and data comparison across countries.
- Health administrators, coders and insurers: clearer medical coding, billing and policy decisions.
- Manufacturers and educators: product labeling, technical documentation and training materials using internationally recognized terms.
How to use
- Use ISO 8549-4 to precisely identify the amputation level, laterality (left/right), and whether the procedure was initial, revision or reamputation.
- Combine with other ISO 8549 parts to describe prostheses, orthoses and broader terminology consistently.

Foreword
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 which 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 matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

This second edition cancels and replaces the first edition (ISO 8549-4:2014), of which it constitutes a
minor revision. The main changes compared to the previous edition are as follows:
— The use of hyphens in anatomical terms, such as transpelvic, has been abandoned in line with other
parts of the ISO 8549 series.

Introduction
At present, no internationally accepted terminology describes the complete range of surgical limb
amputation levels, amputation procedures, and persons who have had an amputation. Members of clinic
teams in different countries have developed their own terminology to meet their own needs.
There is a need for a standard international system of terminology which will allow practitioners to
accurately describe the surgical history of persons who have had a limb amputation(s) and to facilitate
comparisons with the experience of other practitioners.
The terminology will also be of value to epidemiologists and governmental health officials.
