PLATE FOR OSTEOSYNTHESIS WITH COMPLEX FRACTURES OF PELVIC BONE

摘要

Plate for osteosynthesis of complex fractures of the hip bone. It can be used for osteosynthesis for complex fractures of the hip bones. The technical result - a reliable and stable performance of the osteosynthesis plate when a combined treatment of multiple fractures: the horizontal branches of the pubic bone, fracture of the pubic symphysis, fractures of the anterior column acetabular fractures body or the wing of the ilium. The plate is formed with equal cell is curved in the perpendicular plane, and is also curved in its plane, and portions for location on the ileum and pubic bones are made in this plane as smoothly connected circular arcs, with the portion of the arc radius to lock on the ilium 1, 6 ÷ 2,2 larger than the radius of the circle arc portion to lock to the pubic bone, and the centers of circular arcs are situated in this plane on the perpendicular to the chords; the plate length is sustained in the range of 130 ÷ 230 mm; height plates maintained in the range of 40 ÷ 50 mm; in a plane perpendicular to the first edge portion - to lock onto ilium - is at an angle of 45 ° to the second end portion to lock on the pubic bone and with a smooth transition at the middle portion for location on the ileum and pubic bones at their synchondrosis; and the first end portion of the plate is further twisted right or left, respectively, to the right or left to position the pelvic bone at the transition from the body to the wing of the ilium and twist top is displaceable between two cells; length of the cell and the distance between the centers of the locking openings are designed in the ratio 2: 3, the central portion comprises at least four cells, and the locking holes are formed in the edge regions of the cells; comprise edge portions 4 ÷ 8 cells, circular locking hole edge portions formed partially threaded, the upper portion of the spherical shape and with an underlying, lower portion with an eccentric threaded hole for the locking plate locking screw with a rounded head and with a double thread; Extreme cell of the first portion is formed with lateral cuts, and with a rounding at the end.
