An intervertebral implant frame that is configured to be attached to a spacer body can include a pair of arms that extend longitudinally from a support member such that the arms extend substantially around the spacer body. The arms may be configured to expand, crimp, or otherwise engage the spacer body to thereby hold the spacer body to the frame. The spacer body may be made from bone graft.

Intervertebral implants, systems, and methods of use

Described is a rod insertion instrument for the insertion of a fixation rod in the tulips of adjacent pedicle screws in the context of a dorsal spinal column stabilization. It has a grip portion, a tube section adjoining it and a gripping head carried by the tube section, in which gripping head the fixation rod is rotationally fixedly and angularly stably receivable with its proximal end. In order to minimize accidental tissue compression during the fixing of the fixation rod into the pedicle screws, the gripping head is attached to the tube section exclusively via a lockable joint with which there is enabled an unconstrained pivoting movement of the tube section toward the fixation rod during the process of fixing the fixation rod to the pedicle screw.

An implant driver assembly includes an assembly for advancing a threaded implant over a wire. The assembly may include a driver tool with a proximal end, a distal end and a first engagement surface that has a first thread. The driver tool may also include a first wire passage. The assembly may further include a wire locking mechanism with a second engagement surface having a second thread. The second thread is engaged with the first thread to rotatably couple the wire locking mechanism with the driver tool. The wire locking mechanism may further include a second wire passage. The second wire passage may be substantially coaxially aligned with the first wire passage.

Apparatuses and methods for inserting elongated fixation elements into screw implants include one or components for visualizing the insertion process from a unique vantage point. One apparatus features a steering apparatus for adjusting the position of a receiver element on a screw implant, so that an elongated fixation element, such as a rod, can be inserted through a transverse passage in the receiver element. The steering apparatus may include an extension tube and a steering control member coupled to the extension tube. The extension tube may be configured for coupling to the receiver element, and the steering control member may be configured for coupling to the extension tube. The steering control member may include an opening for receiving an endoscope. The endoscope may be used to visually monitor the elongated fixation element as it is inserted into the transverse passage of the receiver element.

Apparatus and method for visualizing insertion of a fixation element into an implant

A non-invasive means and method locates a target spinal segment on a patient prior to surgery. An apparatus comprises a frame; a plurality of laser diodes projecting planar beams and mounted on the perimeter of the frame; a radio-opaque cable attached to the frame at the location of a laser diode; optionally, a weight is attached to the cable; optionally a rod extends from the frame perimeter; and optionally a bombsight is included within the frame marked with crosshairs. The method comprises the steps of marking a patient's skin; placing the frame on the patient; turning on the laser diodes; rotating the frame until the until a line of visible light is perpendicular to the patient's spine; aligning the cable with the planar laser beam; providing an X-ray source; aligning the X-ray source with the planar laser beam and obtaining an X-ray.
