A bone fastener includes a receiver defining a longitudinal axis and an implant cavity. A base is connected to the receiver and includes a wall extending along the longitudinal axis and defining a lateral opening. The base further includes a bearing surface connected to the wall. The wall and the bearing surface define an interior cavity of the base, wherein the bearing surface has a first thickness adjacent the lateral opening and a second thickness adjacent a portion of the wall disposed opposite the lateral opening, the first thickness being greater than the second thickness. The bone fastener further includes a bone penetrating member having a proximal end and a distal end, the proximal end being disposable in the interior cavity of the base. Methods of use are disclosed. |
