MC ETD Wrist Disarticulation
Prosthetist Manual
Introduction
The Wrist Disarticulation option provides an attachment plate that can be laminated directly to the outer
socket of the prosthesis. This minimizes the length of the prosthesis in cases where much of the patient’s
remnant limb has been saved. While it does allow a slight amount of rotational adjustment, it sacrices
passive rotation and interchangeability of terminal devices for the patient.

Instructions
1. Using foam, plaster of Paris, wax or other preferred material, shape the distal portion of the forearm.
Ensure that the inner socket can be removed from the outer socket to allow installation of electrodes,
preamps, wires, and internal battery.
2. Establish the mounting surface for the Lamination Basket. This must be at the correct length and wrist angle.
3. If necessary, use a parting agent (such as a PVA bag) between the forearm material and the Lamination
Basket. This will allow easy removal of material, and removal of the inner socket from the outer forearm.
4. Temporarily attach the Lamination Basket, making sure the “TIPS” marking on the Lamination Dummy
Plate (already installed) is in the direction of the MC ETD ngertips (Figure 2). Otherwise the lamination
basket will be o by 180 degrees.
5. In the lay up, make sure at least 2 stockinettes (4 layers) are rmly tied o in the Tie-O Grove.
6. Remove and add parting agent to each of the 3 hex screws holding the lamination dummy in place.
7. Reinstall the Lamination Dummy Plate and screws.
8. Laminate.

9. Trim the excess lamination away and remove the screws and the lamination dummy. Use care in removing
the last piece of plastic to prevent damage to the attachment plate.
10. Slide the O-ring over the connector and into the groove on the MC ETD (Figure 1). A small amount of
silicone grease will help hold it in place.
11. With the inner socket removed, feed the wire of the MC ETD through the center slot in the attachment plate.
12. Place a small amount of medium strength threadlocker (Loctite 242, 243 or equivalent) on the 3 hex screws
packaged with the MC ETD. Use these screws to attach the MC ETD to the attachment plate. Note that the
attachment holes are slotted to allow some rotational adjustment.
13. With a 3/32 in. ball end hex key, rmly hand-tighten the screws.
