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 spinal stabilization system and method are provided for treating a patient's spinal column, for maintaining preselected spacing and movement between adjacent vertebrae in a spinal column, and for providing overall stability thereto. The system includes an interlaminar member positioned in the space intermediate a first vertebra and the vertebrae positioned immediately below and adjacent to the first vertebra. The interlaminar member is operatively connected to an adjustable support structure and cooperates therewith to maintain the preselected spacing between adjacent vertebrae and to provide overall stability to the spinal column.

A load sensing assembly for a spinal implant includes a set screw having a central opening that extends from a first end of the set screw toward a second end of the set screw. The second end of the set screw is configured to engage with an anchoring member. The load sensing assembly includes an antenna, an integrated circuit in communication with the antenna, where the integrated circuit is positioned within the central opening of the set screw, and a strain gauge in connection with the integrated circuit. The strain gauge is located within the central opening of the set screw in proximity to the second end of the set screw.

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.

A surgical connector useful to link spine rods together. The connector may be used adjacent a pair of mounting screws in one vertebra to limit movement between the screws or may be used to apply a lateral force to a portion of the spine to change curvature. A method of performing spinal surgery is also provided to reinforce a patient's spine.

Spinal device/implants are provided, comprising a spinal device/implant and a sensor.

A spinal implant is disclosed for engagement to portions of a spinal segment after a laminectomy procedure. The spinal implant includes a first member and a second member in orthogonal relation relative to the first member such that the spinal implant generally defines a t-shape configuration. The spinal implant is formed using biocompatible materials to safely adapt to the surgical area. The spinal implant may include hooks or apertures for engaging with portions of bodily tissue. The spinal implant may be engaged to other spinal implants along the spine using one or more arms of an interconnecting arrangement.

A spinal implant system (10) includes a superior attachment rod (12) coupled to, and articulating with respect to, a roller housing (17), an inferior cross bar member (20) coupled to the roller housing (17), and an inferior attachment rod (14) coupled to the inferior cross bar member (20). At least one of the superior and inferior attachment rods (12, 14) is supported by a flexure assembly (16). The inferior attachment rod (14) is coupled to the inferior cross bar member (20) with a swivel joint (32) and/or a telescoping portion (20).

A method of manufacturing a surgical implant includes simultaneously forming a first component and a second component of the surgical implant. Formation of the first and second components includes depositing a first quantity of material to a building platform and fusing the first quantity of material to form a first layer of the first and second components. The method of manufacturing also includes depositing a second quantity of material over the first layer of the first and second components and fusing the second quantity of material to form a second layer of the first and second components. The surgical implant is fully assembled upon the completion of the formation of the first and second components.

Connector assemblies, systems, and methods thereof. One or more modular connectors has a first portion that clamps to a first rod in an existing construct and a second portion that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct.
