Abstract: A spinal-surgery system having a rod receiver and/or a cap for use insertion and removal from the receiver. The cap has a generally cylindrical body, a set of opposing splay-resisting flanges, and set of opposing rotation-preventing wings, the flanges extending radially from the body along a first radial line of the body, and the wings extending radially away from the body along a second radial line of the body generally orthogonal to the first radial line. Each cap flange has a proximal-facing cap splay-resisting surface, and a distal-facing cap pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-resisting surface. The receiver pop-on surfaces are spaced such that each cap pop-on surface contacts a respective receiver pop-on surface when the cap is centered, with the cap wings aligned between receiver arms, and moved distally to contact the receiver.

Abstract: A spinal-surgery system having a receiver for receiving a rod and/or a receiver cap. The cap has a generally cylindrical body and a set of opposing splay-resisting flanges extending radially from the body. The receiver has arms each having an inner proximal protrusion at or adjacent the proximal end, and an inner sloped splaying surface distal of the proximal protrusion. Each cap flange has a proximal-facing cap splay-prevent surface, and a distal-facing cap pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-prevent surface. The receiver pop-on surfaces are spaced so each cap pop-on surface contacts a respective receiver pop-on surface in operation. Each splaying revision surface extends distally and radially inward toward the longitudinal axis and into a cylindrical plane defined by an inner diameter of the cap. The cap inner diameter is greater than a rod width.

Abstract: A spinal-surgery system having a rod receiver and/or a cap. The cap has a cylindrical body, opposing splay-resisting flanges, and an opposing rotation-preventing/rotation-resisting wings, each wing having a lateral rotation-preventing surface and a lateral rotation-resisting surface. A receiver proximal end forms a wing-receiving cavity having a lateral rotation-preventing side and a lateral rotation-resisting side. Each flange has a proximal-facing cap splay-resist surface, and a distal-facing cap pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-resist surface. Each rotation-preventing surface contacts a corresponding rotation-preventing side and each rotation-resisting surface contacts a corresponding rotation-resisting sides when the cap is popped on. The rotation-preventing surfaces contacting the rotation-preventing sides prevents cap rotation in a first direction.
