FINISHING
WARNING: Do not cut or grind fiber braids without air extraction. Fiber particles can cause respiratory illness.
1. Use scissors to cut away fiber braids that are not saturated (Fig. 34).
2. Machine grind and then water grind the edge between the silicone layer of the brim and the resin (Fig. 35).
NOTICE: Do not grind the textile layer of the brim.
3. Sand the edge (Fig. 36). Make sure the edge is rounded and not sharp.
4. Remove unwanted resin from the inside of the socket.

USING THE DIRECT SOCKET
Fitting the Direct Socket
Functioning of the Direct Socket depends on the fit of the whole interface. To achieve comfort, control and
suspension, a socket needs to fulfill basic requirements.
Follow this checklist to control the fit of the Direct Socket:
• The user can securely don the Direct Socket, with or without assistance.
• Liner and inner wall of socket maintain full contact.
• No air pockets develop when user loads the prosthesis.
• Proximal fit is good.
• No pistoning in the socket.
• Visible movement is minimal when pulling on prosthesis.
• Rotational stability is good.
• Full movement is achieved without compromising the distal vacuum.
NOTICE: If feedback from any point in the checklist is not positive, the Direct Socket will need to be adjusted, or
a new Direct Socket needs to be cast.
NOTE: Tell the user to contact a certified prosthetist orthotist (CPO) if suspension is not secure, or if there are
changes in product performance.
Using the Socket
Refer to the Instructions for Use (IFU) of the selected liner and suspension method to don and doff the liner correctly.
For the socket and brim, do as follows:
Donning
NOTICE: Do not pull on the brim when you don the socket. If you pull on the brim, you can damage it. If the brim
is damaged, it can be necessary to cast a new socket.
1. Fold the brim over the socket (Fig. 38).
2. Fully step into the socket (Fig. 38).
3. Fold the brim back up (Fig. 38).
Doff ing
1. Fold the brim over the socket (Fig. 39).
2. Press the release valve and pull the socket off (Fig. 39).
3. Fold the brim back up (Fig. 39).
Prosthetic Socks
Iceross socks can be used to make the socket fit better. Use one or two socks if:
®
• the patient does not feel secure
• contact to the socket is decreased due to volume fluctuations of the residual limb
Refer to the Instructions for Use of the liner to select the correct type of Iceross ® socks.
