Abstract
Metallic materials most suitable for the manufacture of polyaxial transpedicular screws have been analyzed. Choosing titanium alloy Ti-6Al-4V for their manufacture has been justified. When developing the screw design, the requirements for these medical products have been considered. The screws were manufactured on high-performance equipment. During the manufacture, the optimal tool material and cutting part geometry have been chosen. The surface was superfinished and anodic oxide coated. Modern measuring equipment was used to control the product quality and geometric parameters. The manufactured polyaxial transpedicular screw prototypes are not inferior in quality to their foreign analogs. The manufacturing technology proposed allows minimizing the labor intensity of production and 3-6 times reducing the cost of finished products.
