METAL IMPLANT FOR OSTEOSYNTHESIS OF INJURED BONES OF PUBIC SYMPHYSIS OF PELVIC RING Russian patent published in 2015 - IPC A61B17/80 

FIELD: medicine.

SUBSTANCE: metal implant for osteosynthesis of injured bones of pubic symphysis of pelvic ring is shaped as a plate with fixing screw holes. The plate represents a round-cornered flat ring sector, which is a part of the plane between segments of two circles with a common centre and different radii limited by two radial lines to the ends of the segment with a greater radius. Two holes 6.6-6.8 mm in diameter mirror symmetric in relation to a symmetry plane of the plate, having inner sockets 1.45-1.55 mm deep and 9.15-9.25 mm in diameter for pelvic fixing screws are created along the midline of the plate. The centres of the two mirror symmetric holes for the pelvic fixing screws are spaced as much as 20 mm. Two holes 4.1-4.3 mm in diameter mirror symmetric in relation to the symmetry plane of the plate, having inner spherical facets for cancellous screws are created along the midline of the plate. The centres of the two mirror symmetric holes for the cancellous screws are spaced as much as 49.5 mm. There is one working hole with metric screw-thread M 5 at the intersection of the midline and the symmetry plane.

EFFECT: reliable restoration of anatomic shape and bearing function of the pelvis in the absence of recurrences, multiplanar displacements of the fixed bones, improved patient's quality of life.
