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.
