Title	Protocol for Evaluating the Dynamic Compression of Knee and Ankle Arthrodesis Nails
Advisor	Billiar, Kristen, BE
Availability	unrestricted
Abstract It is important for an arthrodesis nail to maintain compression for successful bony fusion. To test new designs of arthrodesis nails a device and protocol were developed to accurately measure compression within a joint over time. The protocol utilized a uniaxial testing machine to cyclically load the samples 10,000 times at 1 Hz from 0-200 lbs. Using Sawbones as a testing model, a 10% decrease in compression was experienced with a standard locked nail. Using this method, new and old designs of arthrodesis nails can be compared to determine which best maintains compression.
