BS ISO 8548-2:2020 Prosthetics and orthotics – Limb deficiencies Part 2: Method of describing lower limb amputation stumps.
4.7.4 Joint pain
Pain in the proximal joint(s) should be recorded.
5 Measurement of lower limb amputation stumps
5.1 Reference levels and reference planes
Identify the reference levels and planes relevant to the particular level of amputation as described in 5.1.2 and 5.1.3.
5.1.2 Reference levels
The level midway between the costal margin and the iliac crest.
184.108.40.206 Iliac crest
The level defined by a line joining the highest point on the crest of each ilium.
The most proximal level at which a circumferential measurement, perpendicular to the mid-line of the thigh, can be obtained.
220.127.116.11 Minimum circumferential
In knee and ankle disarticulation stumps only, the level of the minimum circumference.
18.104.22.168 Femoral condylar
In knee disarticulation and transcondylar amputation stumps only, the level of the maximum condylar ci rc urn feren Ce.
In transfemoral and transtibial stumps only, the level on the stump at which the slope of the stump shape changes as it curves in towards the end.
22.214.171.124 Stump end
The level of the stump end.
126.96.36.199 Medial joint line
The level of the medial tibial plateau, unless there is a fixed deformity of the knee, in which case this level is the highest at which a circumferential measurement perpendicular to the mid-line of the stump can be obtained.
188.8.131.52 Mid-patellar tendon
The level mid-way between the origin and insertion of the patellar tendon.
In ankle disarticulation stumps only, the level of the maximum distal circumference.
The level on which the patient is standing barefoot.
5.1.3 Reference planes used for partial foot amputations
The plane at the posterior aspect of the heel parallel with the mid-line of the leg.
184.108.40.206 Anterior tibial
The plane at the anterior aspect of the tibia at the ankle joint line parallel with the mid-line of the leg.
220.127.116.11 Stump end
The plane at the stump end parallel with the mid-line of the leg.
The plane at the tips of the toes of the contralateral leg parallel with the mid-line of the leg.
This document does not specify the method to be used to obtain the measurements. It specifies both the measurements which should be taken by the team responsible for the rehabilitation of the person and those to be taken only by the prosthetist responsible for the provision of a prosthesis.
