[Stresses in self-compressing plates used for joining bone fragments]

The analysis of the state of stresses in the auto-compression plates after different stages of joining has been carried out. Distinct differences in the values of stresses in the specific zones of plates were detected. The highest level of stress was located near the holes, in the areas where prebending takes place. The main reason of the loss of the ability to carry introduced compressing forces in the joint and possibility of cracks initiation in plates during the operation has been clarified.
