Deformation indicators of metacarpal bones fracture fixation

Abstract

Functional reliability of fixative-bone means was studied for various types of metacarpal fractures depending on the type of fixator and its location. The stiffness characteristics of fracture fixation systems with titanium miniplates were studied, an analysis was performed of the surgical treatment of patients with metacarpal fractures, in which osteosynthesis with needles and external fixation rod apparatus was used, with static and cyclic modes of action of external loads. When transferring a compressive force to a fragment, the type of fixing means significantly influences the deformation of the osteosynthesis system at all levels of stress; for the most of the measured characteristics, rod devices with external fixation and titanium miniplates of various designs are preferable.
