Orthopedic screws and prostheses for use with polymer cables are disclosed herein. An orthopedic screw is configured to retain a polymer cable (12) when the polymer cable is positioned in a thru hole (5) present in the body of said orthopedic screw. This may be accomplished by an orthopedic screw comprising a set screw and a complimentary threaded hole, wherein the threaded hole intersects the thru hole and wherein the polymer cable is secured in the thru hole by tightening the set screw. In an embodiment, the threaded hole extends beyond the thru hole.

It is an object of the present invention to overcome at least some of the problems associated with elongating an existing pedicle screw and rod construct. To this end, there is proposed a spinal rod assembly for elongating an in situ spinal posterior rod system by connecting the spinal rod construct to a head of an in situ bone fastener. The spinal rod assembly according to one embodiment comprises a rod connector and at least one rod fastener, wherein the rod connector comprises a first connector head and a second connector head, connected by an elongated bar, and forming a space between the first and second connector heads. The first connector head comprises a first pocket for receiving a first rod end, while the second connector head comprises a second pocket for receiving a second rod end.

A polyaxial bone anchoring device includes a receiving part having a longitudinal axis, a channel for receiving a rod, and an accommodation space for pivotably holding a head of a bone anchoring element, and a pressure member configured to be positioned in the receiving part and to exert pressure onto the head to lock the head in the receiving part. The pressure member includes a pressure exerting surface and a deformable portion having a free end, wherein the deformable portion is configured to assume at least a first configuration and a second configuration. The polyaxial bone anchoring device further includes a locking member configured to be inserted into the channel and to exert a force onto the deformable portion. When the head and the pressure member and the locking member are in the receiving part, the free end of the deformable portion is supported in the receiving part, and the locking member is movable in the channel along the longitudinal direction in such a manner that the locking member first contacts the deformable portion and exerts a force onto the deformable portion to bring the deformable portion from the first configuration into the second configuration thereby locking the head. Thereafter the locking member comes into contact with the rod and locks the rod.

A method for creating a segmented alignment rod, the method including receiving a request for a segmented alignment rod, receiving at least one image of a deformed spine, generating, a normal spinal curvature, and generating a segmented alignment rod design.

One aspect of the disclosure relates to an aspect of the disclosure relates to an adjustable implant including: a housing; a first adjustable member at least partially positioned within the housing and moveable relative to the housing; and a first actuation assembly positioned within the first adjustable member and configured to move the first adjustable member relative to the housing.

A polyaxial bone screw assembly includes a threaded shank body having an upper portion, a receiver member or head, a retaining and articulating structure, and a pressure insert disposed between the shank upper portion and a rod. The receiver has a U-shaped cradle defining a channel for receiving a spinal fixation rod and a receiver cavity. The retaining and articulating structure attaches to the shank and rotates with the shank in the cavity during positioning. The pressure insert presses upon the shank upper portion and not the retaining and articulating structure.

A spinous laminar clamp system is disclosed herein. The preferred embodiments are either a three or a four-point fixation system at a particular vertebral level. For example, a two-point adjustable fixation below a vertebrae and a single-point non-adjustable point above the vertebrae exemplifies the three-point fixation. Multiple level and further stabilizing is provided by fixation to subjacent vertebrae above and/or below with a connecting rod providing unitization between levels. Specific designs are applicable to the cervical spine; however, fixation at all levels and regions of the human spine are contemplated.

The present invention generally relates to methods and device for treatment of spinal deformity, wherein at least one tether is utilized to maintain the distance between the spine and the an ilium to (1) prevent increase in abnormal spinal curvature, (2) slow progression of abnormal curvature, and/or (3) impose at least one corrective displacement and/or rotation.

Spinal implants and methods of extending pre-existing spinal implant constructs. An extension clamp may be connected to an original spinal implant including an elongated rod attached to a portion of the spine without removal of the original spinal implant. The extension clamp may include a yoke and an extension rod extending from the yoke. The yoke may include a first end and a second end, the first end having first and second rod engaging portions and a channel between the first and second rod engaging portions for encompassing a fastener, and the second end being spaced apart from the first end. The first and second rod engaging portions may be configured and dimensioned to secure the extension clamp to the elongated rod.

A spinal correction rod implant manufacturing process includes: estimating a targeted spinal correction rod implant shape based on a patient specific spine shape correction and including spine 3D modeling, one or more simulation loops each including: first simulating an intermediate spinal correction rod implant shape from modeling mechanical interaction between the patient specific spine and: either, for the first simulation, the implant shape, or, for subsequent simulation, if any, an overbent implant shape resulting from the previous simulation loop, a second simulation of an implant shape overbending applied to the targeted spinal correction rod implant shape producing an overbent spinal correction rod implant shape representing a difference between: either, for the first loop, the targeted spinal correction rod implant shape, or, for subsequent loop, if any, the overbent spinal correction rod implant shape resulting from the previous simulation loop, and the intermediate spinal correction rod implant shape.
