Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Patients with severe spinal lateral deformity will consider for surgical intervention due to cardiopulmonary and cosmetic compromise. However, the current operation making use of conventional metals can only achieve 60-70% correction due to the spinal viscoelastic properties. Hence, spinal implants making use of the shape memory effect of nickel titanium shape memory alloy have been developed to overcome these problems. Nevertheless, the surgical outcome did not significantly differ with the conventional implants. The invention new spinal system is still needed in order to achieve better spinal deformity correction.
