An interbody fusion cage having upper and lower canals for receiving the heads of bone screws that have been pre-installed in opposing vertebral body endplates. The proximal wall of the cage preferably has a vertical slot that communicates with each canal and is adapted to allow access by a screwdriver and tightening of the screws.

Zero profile spinal fusion cage

A novel posterolateral inter-muscular approach has been developed to access the cervical. spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises: Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

Method and devices for a sub-splenius/supra-levator scapulae surgical access technique

A novel posterolateral inter-muscular approach has been developed to access the cervical spine. The approach includes elevating the splenius capitis and trapezius muscles dorsally to create a window for deep spine access, wherein the window comprises: Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

A method of delivering a fusion cage to an intervertebral disc space bounded by adjacent vertebral endplates, comprising the step of delivering the fusion cage into the disc space without contacting its teeth to the vertebral endplates during delivery, wherein a sheath is interposed between a cage surface and the endplates to prevent contact therebetween during delivery.

Enhanced cage insertion assembly

Devices and methods for enhancing the effectiveness of spinal stabilization, and particularly that of cervical spinal stabilization, are provided herein. More specifically, methods and systems are disclosed for effectively positioning occipital plates and spinal fixation assemblies within target vertebrae, while also reducing any associated patient trauma (e.g., muscle stripping, tissue damage, etc.). The systems and methods can utilize trans-lamina delivery of the spinal fixation assemblies to allow for the positioning of the fixation elements along the midline of the patient's spine.

System and method for cervical midline fixation

A novel posterolateral inter-muscular approach has been developed to access the cervical spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises: Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

The present invention concerns several fusion devices and methods for laterally inserting a fusion device at an initial trajectory that is not parallel to the disc space. Each fusion device incorporates components that enable flexing, bending or pivoting of the device during its final approach to the prepared disc space.
