BACK DISTAL BACK PLATE COMBINED FOR OSTEOSYNTHESIS OF THE HUMER BONE

摘要

The utility model relates to medicine and medical equipment, namely to traumatology and orthopedics, and can be used in surgical treatment of patients with fractures and false joints of the lower third of the humerus, including osteoporosis. A plate for the humerus osteosynthesis containing diaphyseal , metaphysical and transitional parts with holes for screws with angular stability, as well as compression and oval holes for cortical screws having a spiral bend-twist to bypass the radial nerve and the bend in the sagittal plane, corresponding to the normal anatomy of the lower third of the humerus, in the transitional part of the plate there are oval holes for possible fixation of bone grafts, while the compression holes are made of an intermediate size with the possibility of fixing with screws with a diameter of both 3.5 mm and 4, 5 mm, and the metaphysical part contains an installation round hole for cortical screws with a diameter of 3.5-4.5 mm, as well as two rows of holes for screws with angular stability with a diameter of 3.5 mm and a branch of the plate, rientirovannuyu on condyle of humerus head, according to the utility model plate is made of titanium or its alloys as the surface of the plate by sputtering electroexplosive bioinert applied composite coating based niobiya.Elektrovzryvnoe deposition leads to the formation of highly dispersed and uniform coating structure. The advantage also lies in the formation of a surface layer with high coating adhesion with a titanium substrate, low roughness and a homogenized structure, which increases the life of the implants and expands the field of practical application. 4 ill.
