Abstract

A bone fastener assembly for connecting a bone to a stabilizing construct includes a connecting member, a fastener seat, and a bone fastener. The connecting member includes a connecting member axis, a first opening, a second opening, and a first spherical surface. The connecting member axis extends from a proximal end to a distal end. The first opening is adjacent the proximal end. The second opening is adjacent the distal end. The fastener seat includes a first end, a second end, a passageway, and a second spherical surface. The passageway extends from the first end to the second end along a seat axis. The second spherical surface is configured to slidably engage the first spherical surface. The bone fastener includes a shank and a head. The shank extends though the passageway. The head engages a head-mating surface of the fastener seat.
