Definitive Prostheses
Once you are ready to proceed with definitive fabrication, we can do several types of final laminations including:
- Rigid: Standard external frame, typically laminated. Other materials can be specified in the notes section of order form.
- Heavy-Duty: Extra reinforcement indicated for use with high activity levels
- Flexible Proximal Brim: Provides additional comfort with flexibility around trim lines



Adding a flexible inner socket provides enhanced comfort for the user, which can lead to increased prosthetic wear time. There are several material options to choose from, including:
- ThermoLyn Supra Flexible (available in 16 colors, please see chart below)
- Most flexible option
- Highest coefficient of friction to maximize suspension and control rotation
- Maintains shape over time
- Highest patient comfort
- Works well when donning a suction socket with donning sheath
- Typically draped for fabrication

- ThermoLyn Supra Soft
- Greater stability, less flexibility
- High coefficient of friction to aid in suspension and rotational control
- ThermoLyn Supra Soft Plus Silicone
- Stability and flexibility of Supra Soft, with greater comfort
- High coefficient of friction to aid in suspension and rotational control
- ThermoLyn Soft
- Highest rigidity
- Lowest coefficient of friction for ease of donning and doffing
- Works well for “push-in” or “pop-in” style donning
- Highest stability
- Typically blister-formed for fabrication
- Available in 3 colors (jet black, Caucasian and white)
What is required for definitive fabrication?
*If using non-Ottobock components, they must be shipped with finished test socket for definitive fabrication
- Completed test socket:
- no further modifications required
- clearly marked trim lines for both flexible inner socket and external frame
- clearly marked alignment lines
- Completed Myo UL iFab Order Form with lamination and flexible inner socket choice, componentry specifications, and measurements
- Please specify surface finish (lamination color, clear-coat, custom fabric, etc.) *If custom fabric is chosen it must be shipped with finished test socket for definitive fabrication
- Please specify rigid socket material in the notes section of the order form (carbon, fiberglass, etc.)
- Photos of the test socket or rough trial set up can also be helpful
- Clearly marked locations for switches, linear transducers, valves, battery charging port, etc.
