Abstract
Methods for installing bone anchors, such as pedicle screws or other surgical screws. In some implementations, the surgical screw may be coupled with a connection member, such as a tulip assembly, configured to couple the surgical screw with a stabilization member, such as a spinal fixation rod. The connection member may be initially coupled with the surgical screw in a polyaxial configuration, after which the connection member may be secured to the surgical screw in a monoaxial configuration. The stabilization member may then be coupled and secured with the connection member such that the stabilization member cannot move relative to the connection member. In some implementations, the stabilization member may be locked or secured to the connection member after the connection member has been secured to the surgical screw in a monoaxial configuration.
