Distal radius fractures are prevalent, debilitating, and costly. This thesis conducts an in vitro investigation of these injuries, examining the role of static muscle loading on fracture threshold measures (i.e., force, impulse, energy). Initially, an impact apparatus and custom LabVIEW colour-thresholding program were designed and assessed for repeatability and accuracy in quantifying fracture measures and impact kinematics. These tools were then used to test six pairs of cadaveric forearms, with static muscle loads simulated in one specimen from each pair. Distal radius fractures were achieved in 5 pairs, with perilunate dislocations in the remaining pair. None of the fracture ...
