  • Instruments and methods for delivering bone cement to a bone screw
    Patent number: 12605195
    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.

  • Screw inserter instruments and methods
    Patent number: 11123113
    Abstract: Screw inserter instruments and methods for implanting a bone screw are disclosed herein. In one exemplary embodiment, a screw inserter instrument can include a driver shaft, a retaining sleeve disposed around the driver shaft, and a locking sleeve disposed around the retaining sleeve. The locking sleeve can have a first position in which rotation of the driver shaft causes corresponding rotation of the retaining sleeve while the locking sleeve is held stationary, and a second position in which rotation of the locking sleeve causes corresponding rotation of the retaining sleeve while the driver shaft is held stationary.
