Polyaxial bone screw with lateral connector
View Patent ↗A polyaxial screw body includes a side wall defining a lumen having a first end and a second end. An opening disposed at the first end of the lumen, includes an interior surface disposed in the side wall thereabout. The interior surface is adapted to accommodate a head portion of a pedicle screw. A transverse channel extends from a first aperture through the side wall to a second aperture and is adapted to accommodate a portion of a fixation rod therebetween. A lateral connector extending integrally from the side wall.
1. A sacral to lumbar fixation system comprising:
a polyaxial screw including
a proximal end with a first head and a distal end for attachment to a vertebra;
a first body member defined by a side wall and including a lumen having a proximal end and a distal end;
a first opening at the distal end of the first body member that receives the first head of the polyaxial screw;
a first transverse channel formed in the proximal end of the first body member extending from a first aperture in the side wall to a second aperture in the side wall and that receives a fixation rod; and
a lateral connector including a tubular shape integral with the first body member and extending radially away from the side wall at an angle relative to the first transverse channel; and
a pelvic fixation device including
a proximal end with a second head and a distal end for attachment to a sacrum;
a second body member defined by a side wall and including a lumen having a proximal end and a distal end;
a second opening at the distal end of the second body member that receives the second head of the pelvic fixation device; and
a second transverse channel formed in the proximal end of the second body member extending from a first aperture in the side wall to a second aperture in the side wall that receives the lateral connector.
