THE LAMINATION
COLLAR AND CLAMP RING
6.1 Orientation of the Lamination Collar and
Clamp Ring
The lamination collar must be oriented properly relative to the
patient socket to allow for correct internal / external humeral
rotation and to protect the wiring of the Espire Elbow.

Colours for representation only.
The clamp ring is a two-piece assembly that is uniquely shaped
to fit the profile of the Espire Elbow. When assembled to the
elbow, the clamp screws will face posterior.
6.2 Internal-External Rotation
The Espire is designed with a humeral anti-rotation stop pin to
prevent 360-degree rotation. This feature is to prevent input
wires from being twisted and potentially damaged. The anti-
rotation stop pin allows for 100° external / 100° internal rotation
for a total range of 200°.
Info:
Normal human range of motion is 30° externally
and 135° internally.

6.3 Attaching the Lamination Collar to the Elbow
1. Disassemble the clamp ring by
removing the fasteners.
2. Place the lamination collar (or
socket with attached collar)
near top of the elbow.
3. Plug appropriate cables into
the input board (if applicable,
see section 2.3).
4. With the laminating collar
in place, insert Clamp Ring
A (green) around both the
anterior end of the lamination
collar and elbow attachment.
5. Then insert Clamp Ring
B (pink) around both the
posterior end of the lamination
collar and elbow attachment.
6. Insert the fasteners and torque,
(hand tighten to start and
then tighten until appropriate
friction is achieved for humeral
rotation). Apply equal torque
to both fasteners.
