Fitting instructions

Precautions and warnings:

  • Wounds or damaged skin should be covered with an appropriate dressing to prevent direct contact between the wound and socket.
  • Ensure the socket is clean and free from foreign matter that may cause irritation.

Socket fit

The fit of the socket is based on the measurements and a mould of the residual limb.
Note: If there is a change to body weight, or residual limb shape, this will affect the socket fit. If the socket is not fitting correctly the socket will need adjustment or replacement.

Care and cleaning

Note: daily cleaning of the residual limb is essential. Use of mild, pH balance fragrance and dye free liquid soap is recommended. If skin is dry, apply a pH balance fragrance and dye-free lotion to nourish the skin.

  • It is essential to take proper care of the socket and clean it following use with pH balanced and dye-free soap and dry with a lint free cloth.
  • If a liner is worn this should be washed daily in accordance with the manufacturer’s instructions.
  • The socket should be checked for wear and damage and patients are advised to contact their Prosthetist immediately if any damage is evident.
  • Patients should monitor skin health daily. In case of abnormal symptoms, the user is advised to discontinue the use immediately and contact their prosthetist.
  • Other common household or bath products may cause or contribute to skin irritation.
