Devices, systems, and methods for inserting a vertebral stabilization member, such as a rod. The insertion device includes an outer guide tube, a pin assembly including a pin and a pusher member extending therethrough. The insertion device is configured to actuate a rod between a first orientation and a second orientation angled with respect to the first orientation in order to position the rod in an appropriate location for attachment to bone.

A horizontal-transvertebral curvilinear nail-screw (HTCN) including a body portion having a first end and a second end, wherein the first end is opposed to the second end; and a head at the first end of the body portion, wherein the body portion has a predetermined curvilinear shape and includes a pointed tip at the second end of the body portion, and a method of surgically implanting universal horizontal-transvertebral curvilinear nail-screws (HTCN) into a plurality of adjacent vertebrae.

Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and/or derotating the spine and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

Connector assemblies, systems, and methods thereof. A connector has a first end that clamps to a first rod in an existing construct and a second end, connected to the first end, that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct at an adjacent level as the existing construct.

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. Instruments are provided to aid in insertion and positioning or the rod.

A spinal pedicle screw system includes distractions rods and has the ability to be distracted after the screws are inserted into the pedicle and maintain polyaxial motion via polyaxial joints.

A distraction system includes a distraction rod having one end configured for affixation to at a first location on patient. The system further includes an adjustable portion configured for placement in the patient at a second location, the adjustable portion comprising a housing containing a magnetic assembly comprising a magnet, the magnetic assembly secured to a threaded element that interfaces with an opposing end of the distraction rod. The system includes a magnetically permeable member in proximity to the magnetic assembly and covering an arc of less than 360 of the adjustable portion.

A device for bracing the vertebrae of the human spinal column, having at least one pedicle screw with a head that is formed so as to be at least partially spherical and that is received into an at least partially spherical mounting area of a pedicle head, wherein the pedicle head has a centric recess which includes the mounting area and a slit for receiving a rod that is arranged transversely with respect to the centric recess, as well as an internal thread which is formed inside the centric recess opposite the mounting area and inside of which a safety screw for clamping the rod is arranged, wherein the safety screw is provided with an anti-rotation device at that side that is facing towards the rod.

A soft dynamic stabilization assembly includes a core, typically in the form of a tensioned cord, at least one pair of bone anchors, a spacer surrounding the core located between the bone anchors, typically, at least one elastic bumper and at least one fixing or blocking member. The core is slidable with respect to at least one of the bone anchors and cooperating spacer.

Connector assemblies, systems, and methods thereof. A connector has a first end that clamps to a first rod in an existing construct and a second end, connected to the first end, that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct at an adjacent level as the existing construct.
