Abstract
A spinal fixation device is provided having first and second elongate members that are angularly adjustable relative to one another. Each elongate member can include a connecting feature formed on a terminal end thereof, and each connecting feature can be coupled to one another to allow angular movement of the first and second elongate members. The device can also include a locking mechanism that is adapted to couple to the connecting feature on each of the first and second elongate members to lock the elongate members in a fixed position relative to one another.

A spinal fixation system, comprising:
- a first elongate member having a female connector with opposed arms and a second elongate member having a male connector configured to be received between the opposed arms of the female connector, the first and second elongate members being movably coupled to one another;
- a pin that extends through at least a portion of the male and female connectors so that the male and female connectors are movably connected to each other, the pin having a central axis about which the male and female connectors rotate and which extends substantially perpendicular to longitudinal axes of the first and second elongate members;
- a threaded locking screw configured to engage the male connector to lock the first and second elongate members in a fixed position relative to one another;
- and
- a spinal anchor implantable in bone and configured to mate to at least one of the first and second elongate members;
- wherein the first and second elongate members are biocompatible, internally implantable spinal rods.
A spinal fixation system, comprising:
- first and second elongate members, each having a connector integrally formed on a terminal end thereof, the connectors being coupled to one another such that the first and second elongate members are angularly adjustable relative to one another along a plane;
- a pin extending through at least a portion of the connectors;
- a fastening element configured to extend into one of the connectors along an axis that is substantially parallel to the plane to lock the first and second elongate members in a fixed position relative to one another;
- and
- a spinal anchor implantable in bone and configured to mate to at least one of the first and second elongate members;
- wherein at least one of the first and second elongate members is a biocompatible, internally implantable spinal rod.
A spinal fixation system, comprising:
- a first elongate member having a male connecting feature integrally formed on a terminal end thereof;
- a second elongate member having a female connecting feature integrally formed on a terminal end thereof, an angular position of the first elongate member with respect to the second elongate member being adjustable by rotating at least one of the male and female connecting features about a pin that extends through the male and female connecting features;
- and
- a fastening screw configured to be advanced with respect to the male connecting feature to engage the male connecting feature with the fastening screw and lock the first and second elongate members in a fixed position relative to each other;
- wherein at least one of the first and second elongate members is a biocompatible, internally implantable spinal rod.
