Modular reconstruction assembly for hip joint prosthesis has acetabular cavity support plate fixed with pile screws, spacer and metal cup

摘要

The modular assembly consists of a support plate (2) positioned and anchored by pile screws (1), a spacer (3) fastened to the support plate by conical surfaces, and a metal cup (4) joined to the spacer by conical surfaces. The modular assembly consists of a support plate (2) positioned and anchored by pile screws (1), a spacer (3) fastened to the support plate by conical surfaces, and a metal cup (4) joined to the spacer by conical surfaces. The anchoring screws are designed to allow fine adjustment of the support plate's thrust surfaces and a balanced adjustment of pressure forces, each one having a pointed shank and a cylindrical body with a threaded hole for a piston receiving a threaded counter screw.
