College Park Truper Owner's manual

TECHNICAL INSTRUCTIONS
The durable Truper was designed to combine stability, dynamic response
and two flexible size ranges to take on the toughest of childhood challenges.
The foot’s dynamic response stores and releases energy for a smooth and
controlled transition from standing to running.

Stride Control Adjustment
The adjustable Stride Control gives you the ability to customize an individual’s gait timing, fine-
tuning the foot’s response by either turning it clockwise/ counterclockwise. This adjustment
affects both plantar and dorsiflexion resistance without the need to change soft components.
The Truper ships with a medium Stride Control setting. If new bumpers are fitted, set the
preload to 3-turns (medium preload) from the point of initial contact with the Foreheel Bone
assembly. If an additional 1-1/2 turns are required to attain the desired resistance, then a
change in bumpers is recommended.

GENERAL INSTRUCTIONS
Endoskeletal Mounting
Use only high quality proximal endoskeletal components (22 mm).
Exoskeletal Mounting
1 Remove Exo Ankle Bone, then attach to College Park Exo Block with anti-rotation pin(s)
oriented. Apply Loctite® 242 to mounting bolt. Torque to 47 N·m (35 ft·lbs).
To skip alignment and lamination, go to Step 9.
2 If using the alignable Exo option, attach Exo Pyramid Tool to Exo Block with four 5 mm
screws. Torque to 15 N·m (11 f t·lbs).
3 Attach 22 mm endo components to the Exo Pyramid Tool and temporarily mount the socket.
4 Re-attach the ankle bone to foot, donning CPI Sock and foot shell, then perform a dynamic
alignment.
5 Remove foot from Exo Block.
6 Mount aligned prosthesis in transfer jig. Lock socket and Exo Block in position.
7 Remove endo components and Exo Pyramid Tool.
8 Use desired method to span Exo Block to the socket and remove from jig. Shape and
laminate to desired finish. Do not remove foam from the top of the Exo Block.
9 Re-attach ankle bone to foreheel.
10 Re-assemble foot, don CPI Sock and foot shell.
Assembly and Disassembly
1 Use the FootHorn to don and doff the Foot Shell. Remove the CPI Sock and replace
as needed.
2 Use a 4 mm hex key to reduce the preload on the bumpers by turning the Stride Control
adjuster counter-clockwise. Record the number of turns for use in re-assembly.
3 Use two 4 mm hex keys to remove the axial pin screw and axial pin.
4 Remove the ankle bone from the foreheel to access the front and rear bumpers and
ankle bushings.
5 For re-assembly, lubricate the axial pin, inside and outside of the ankle bushings and ankle
bushing pocket, then reverse steps 1-4. Torque axial pin screw to 4 N·m (36 in·lbs).
Do Not lubricate front and rear bumpers.
Static Alignment
For optimal function have the patient’s weight balanced between the forefoot and heel.
The load line divides the foot at 1/3 heel lever and 2/3 toe lever.
