4 Stump description
4.1 General
Specify the amputation side and describe the stump using the relevant descriptors listed in the appropriate tables (Tables 1 to 7) and the guidance given in 4.2 to 4.6.
4.2 Stump characteristics
The shape of the stump should be described as either conical, bulbous or cylindrical. In this context, the meanings of these terms are self-evident. The soft tissues of the stump should be described by reference to their amount and consistency. The amount should be described as sufficient, insufficient or excessive and the consistency described as normal, flabby or indurated. If the heel pad is retained, its position should be recorded as correctly positioned, displaced or mobile. It is important to record whether the stump musculature is attached, detached or displaced. Relevant bony features such as prominences, remnants, length or position should be described. The presence of any prominent foreign bodies, for example grafts, implants or shrapnel, should be noted.Where appropriate, the end-bearing status of the stump should be recorded. For partial foot amputations, record the level of amputation specified in ISO 8549-4. The complete description requires the identification of the amputated bones and their levels of amputation.
4.3 Skin
Record whether the skin barrier is intact or not, and whether the skin has normal sensation. The position/orientation of the incisional scar and whether it is healed or not and mobile or adherent should be recorded. Additionally, the presence and condition of other scarring or skin grafting should be noted. Any history of skin pathology, for example contact dermatitis, skin allergy and/or hyperhidrosis, should be noted.
