Use of Implants on the Basis of Silicium Monocrystals for Prevention of Extremities' Deformity in Physis Damage (Experimental Study)

Experimental study of the influence of crystalline silicium upon the damaged physis of the proximal femoral growth zone was performed in 24 Chinchilla rabbits. Defect of growth zone was created by drilling (2.6 mm in diameter). In first experimental group a metallic screw was inserted into the created defect. In the second group silicium monocrystal 5x5x0.5 mm was placed into the defect next to the metallic screw. In control animals only the defect was created. In animal from 1st and control groups roentgenological picture showed the development of deformity in the operated extremity. No deformity was detected in animals from 2nd experimental group. Positive effect of crystalline silicium upon the damaged growth zone function was noted. Further study of this phenomenon may be perspective for the elaboration of new implantation materials with a view to stimulate regeneration of affected physis, preservation of its function, bones deformity prevention and correction.
