Pedicle screw having a removable rod coupling
A pedicle screw for spinal fixation having a bone fastener portion a permanent rod coupling, a breakaway portion connected to the permanent rod coupling and a temporary rod coupling. A permanent rod can be positioned in the permanent rod coupling and a temporary rod can be positioned in the temporary rod coupling and when the temporary rod is not needed the temporary rod coupling can be removed by separation at a breakaway portion.
Post-Operatively Adjustable Spinal Fixation Devices
A system for spinal fixation with a non-rigid portion at least one of the caudal or cephalad terminus. Various devices and techniques are described for transition from a rigid fixation construct to a less rigid support structure applied to a “soft zone” that will help share the stress created on the spinal levels caused by the fixed levels below. In specific embodiments the soft zone is provided by terminating the construct with one of a flexible tether or a dampening rod.
Articulating connectors, systems, and methods thereof
Connector assemblies, systems, and methods thereof. An articulating connector has a first end that clamps to a first rod in an existing construct and a second end having a second end that clamps to a second rod in a new construct or such that the new construct can be extended from the existing construct. In the case of different sized constructs used in different areas of the spine, an articulating connector has a first end that clamps to a first rod in a new construct having rods of a first size and a second end having a second end that clamps to a second rod in a new construct having rods of a second size. The clamping portions are capable of translating and rotating with respect to each other.
MULTIPLE DIAMETER SPINAL ROD CLAMPING MECHANISM
A cross-connector for spinal rods includes an adjustable rod clamping mechanism that adjusts to a variety of rod diameters to be clamped on each side of the cross-connector. The adjustable rod clamping mechanism includes a fixed hook portion and a cross-slide cam driven by a tapered set screw that is oriented 90 degrees to the travel of the cam.
Splay control closure for open bone anchor
Open implant closure structures include a helically wound guide and advancement flange form having splay control surfaces. Multi-start closures and closures with inner set screws have splay control contours for interlocking with cooperating flange forms of bone anchor receivers. Flange form heights, thicknesses and other geometry, such as splay control ramp angle may be varied.
Trans-iliac connector
A spine stabilization implant includes a first portion having a first fixed angulated extension, a first rod receiving element and a connecting element. The implant also includes a second portion having a second fixed angulated extension, a second rod receiving element, and a receiving portion for receiving the connecting element of the first portion. The second portion is configured with a locking assembly for locking the first portion and second portion to one another.
Spinal Cross-connector
A spinal cross-connector comprises an elongated member, a first connector and a second connector. The first connector and the second connector are configured to receive spinal rods and adaptable to directly attach with pedicle screws. The first connector includes a first collet head, a first clamp and a first locking means. The second connector includes a second collet head, a second clamp and a second locking mans. The first locking means is configured to tighten over a first collet head and engage with the first connector. Similarly, the second locking means is configured to tighten over a second collet head and engage with the second connector. The engagement of the first locking means with the first connector and the second locking means with the second connector locks the spinal cross-connector.
Transverse connector
A transverse connector includes a cross member connecting assembly, and first and second spinal rod connection members rotatably coupled to opposing end portions of the cross member connecting assembly. The cross member connecting assembly includes a first band slot defined therethrough and a threaded opening extending through an upper surface of the cross member connecting assembly and into the first band slot. The cross member connecting assembly includes a band set screw threadingly engaged with the threaded opening and movable relative to the first band slot.
Multiplanar bone anchor system
The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A bone anchor is provided. The anchor can include a bone fastener. The bone fastener can include a head and a second end adapted to engage an anatomy. The bone fastener can extend along a longitudinal axis. The anchor can also include a coupling arrangement coupled to the head of the bone fastener so that the bone fastener is rotatable about the longitudinal axis to define a first plane of motion. The anchor can further include a saddle, which can be coupled to the coupling arrangement. The saddle can be movable relative to at least one of the bone fastener and the coupling arrangement to define a second plane of motion.
Cross connectors, kits, and methods
Cross connectors, kits, and methods useful in the treatment of bones, such as vertebrae, are described herein. An example cross connector is comprised of a first member, a second member, a saddle, a locking member, and a stop member. The first member is pivotally, rotatably, and slidably moveable within a passageway defined by the second member.
