Biomechanical Testing

Figure 1: Cantilevered bend test of a canine metatarsal

We produce novel testing methods and apparatus to answer complex biomechanical questions in applications such as orthopedic surgery, tissue engineering, and mechanics of materials. Pictured above is a testing mockup for a cantilevered bending test for a canine metatarsal. This experiment was designed to evaluate two different fracture fixation methods.

Screw Pullout Testing

Below you can see of a video of a screw pull-out test on an equine (horse) metatarsal. This 5.5mm buttress threaded screw implanted mid-shaft into the bone required over 1,500 pounds of force to cause failure of the bone:

Novel Physiological Compression for a Horse Hock

This experiment shows a physiological compressive bending experiment on hocks taken from horse cadavers. This study is comparing the strength of different methods for fusing this joint (arthrodesis) which can save a horses life if they are injured.

Screw Insertion

Below you can see a similar screw insertion test on a bone screw fastener implanted into an equine metatarsal.
