摘要:
#$%^&*AU2014200463A120140821.pdf#####Abstract The present disclosure is directed to a polyaxial screw including a housing, a bone screw member, a wedge member and an insert. The bone screw member is selectively positionable at a plurality of angles relative to the housing when engaged to the housing and securable relative to the housing at a cone angle of up to approximately 80 degrees. The bone screw member includes a head and a threaded shaft extending from the head. The head is selectively securable within the housing by use of the insert member. The head may include surface texture that frictionally engages with the wedge member such that a user applied force is necessary to reposition the bone screw member relative to the wedge member when the bone screw member is disposed in engagement with the wedge member. The wedge member is positionable within the housing adjacent to the head of the bone screw member when the wedge member and the head of the bone screw member are positioned within the housing. A set screw is positionable within the housing to secure a rod member within the housing adjacent the wedge member.0 a-. K d
