Goals
Create proof-of-concept device to ensure feasibility
Gain physician feedback on pros and cons of this method
Confirm MDF board as a capable prototyping material for future alterations
Ensure sizing for all of target patient population

Manufacturing methods
Back support wall, rotating arm board, and main table each made from two 0.25" medium density fiber-boards that were laser cut and glued together with wood glue
Screws, washers, and wingnuts purchased from McMaster
Table adapter hub machined from block aluminum
0.5" aluminum stock tubing and off the shelf operating table adapter used for support
Functional aspects
Back support wall can be locked into indents to support the patients elbow
Rotating arm board can relocated and locked at correct distance and angle using notches and wingnut
Adjustable table height through off the shelf operating table attachment
Physician feedback
Good idea overall concept
Need a more easy to understand locking and setup system
Avoid metal for fluoro compatibility
Need better securement methods particularly at the wrist

Lessons Learned
Pinch Points at elbow support and rotating arm board attach point
Notches don't work for ease of use, smooth sliding would be better
Locking needs to be easier than set screws and wingnuts
Positioning fits wide variety of body sizes
Particle board flexing minimal, but present and could be reduced
Improved attachment method needed for wrist
