Background
failure of partially ruptured, rupture, injuries
Triceps tendon ruptures are rare injuries and occur most often in middle-aged, physically active men [Further, indication for surgical treatment of partial ruptures is still controversially discussed. Although not based on scientific data, a rupture size of > 50% of the tendon is often given as an indication for surgical treatment [The purpose of this study was to determine whether the ultimate load to failure of partially ruptured and intact triceps tendons differ significantly, and further to describe the rupture mechanism. The hypothesis was that there will be no significant differences in ultimate load to failure and that the superficial tendon fibers would rupture primarily.
