In vitro tensometric measurements of the tensions caused by NiTi alloy springs with memory in metal tubes and human femurs.
The aim of this paper is to quantify tangential and axial tensions that develop within metal tube and human femur after insertion of a NiTi alloy spring following the activation of memory shape effect. We can see that resulting tensions inside the bone caused by the mentioned NiTi alloy springs are safe as far as the bone solidity is concerned. Intramedular fixation strength is satisfactory enough to bring about osteosynthesis. Therefore we recommend to use NiTi alloy springs with memory shape effect for intramedular osteosynthesis of long bones. (Fig. 20, Ref. 10.)
