    Abstract: Bone anchor assemblies are disclosed herein and include bone anchors, receiver members, and closure mechanisms. In one embodiment, a receiver member can be configured to seat a portion of a bone anchor and to receive a spinal fixation element, such as a rod. In an exemplary embodiment, the receiver member is bottom-loading and can include a seat having an opening that can be selectively increased and decreased in size so as to allow a bone anchor to be bottom-loaded. A force can be applied to the receiver member to increase a size of the opening, allowing a portion of the anchor to pass through the opening and into the seat. A closure element can be coupled to the receiver member and can apply a force to decrease a size of the seat and a size of the opening, angularly fixing the receiver member relative to the bone anchor.

    Abstract: Instruments and methods for delivering bone cement are disclosed herein. In one exemplary embodiment, the instrument includes a cannulated bone screw having a head that is configured to be received within a rod receiver and a shank extending distally from the head and configured to extend distally from the rod receiver, a cannulated shaft having a distal end configured to extend into the shank of the cannulated bone screw and a proximal end configured to couple to a bone cement delivery system, and a retaining sleeve disposed around at least a portion of the cannulated shaft. The head of the bone screw has proximal and distal recesses therein, and a distal end of the retaining sleeve is configured to couple to the proximal recess.

    Abstract: A cannulated bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, and a closure mechanism to fix the spinal fixation element with respect to the receiver member. The bone anchor includes a distal shaft having a first threaded section distal to a proximal head, a second threaded section distal to and adjacent the first threaded section, and a third threaded section distal to and adjacent the second threaded section. The first threaded section having a constant major and minor diameter. The second threaded section having a tapering major and minor diameter. The third threaded section having a tapering major diameter and a constant minor diameter.
