A spinal implant system includes a pair of spinal rods arranged on opposite sides of the spinous processes of a patient. An transverse connector assembly in accordance with the invention includes a plate having a central portion which spans between the spinal rods. At each end of the central portion is an integral body portion having an elongated slot formed therein. An eyebolt extending through the slot and has an opening to receive the spinal rod therethrough to clamp the spinal rod to a respective one of the body portions. At the end of each body portion distal from the central portion is an enlarged end piece having an end face oriented generally perpendicular to the longitudinal axis of the slot in the plate body. A threaded post extends from the end face and is used together with a nut to clamp the yoke portion of the vertebral fixation element to the plate. In another embodiment, an eyebolt assembly is used to mount a vertebral fixation element to an endpiece bar extending from the plate.

A motorized drill is mounted in the handle of a Kerrison Rongeur System utilized by a surgeon to perform surgical procedures on a patient, includes mechanism for moving the rotating drill toward the fixed upstanding foot mounted at the remote end of the pistol-shaped handle for removing bone which is located between the upstanding foot and the drill bit. In another embodiment, the drill is removably fixed in the handle and the foot moves relative to the drill bit. In either embodiment a trigger operated by the surgeon actuates the foot/drill and the trigger is biased to maximize the space between the foot and the drill bit. The foot shape and dimension can be modified for perfecting given surgical procedures. In one embodiment the drill motor releasing mechanism includes a pinion gear and rack performing the additional function of releasing the motor locked in position in the handle.

Various implementations for therapy to facet joints connecting vertebrae are disclosed including: A) Facet joint stabilization that may be implemented using stabilization band that maintains tension between two anchors. The stabilization band may be retained in any one of a number of ways including the use of an anti-slip device such as a mechanically deformed crimp that abuts one of the anchors. B) Facet joint augmentation may be implemented by dilating the facet joint and inserting a facet joint spacer before adding a facet joint stabilization assembly. The facet joint augmentation may include connecting a tail section of the facet joint spacer to the first anchor used in the facet joint stabilization assembly. C) Facet joint immobilization may be implemented by inserting a fastener across the facet joint and into the vertebra so that the assembled fastener expands inside the vertebra.

Devices and methods for removing body tissue involving the use of a brush member having a plurality of bristle members defining a capacity for carrying body tissue. The brush member is capable of being manipulated within said body to thereby receive body tissue within said brush member such that said body tissue may be carried and thereafter removed from said body. Also provided are protective devices dimensioned to be positioned near an entrance into the target site, the protective devices for establishing a barrier between the brush member and at least a portion of the body tissue adjacent to the entrance. The protective devices may comprise one of a cannula assembly and a retractor assembly.

A variable angle bone screw system for use in a spinal implant system to connect a vertebral fixation element to a spinal rod extending adjacent the vertebral column in a patient. The system includes an eyebolt having a threaded stem, a washer receivable over the stem of the eyebolt, a bone screw including a yoked head to permit top loading of the stem of the eyebolt, and a nut engaging the threaded stem of the eyebolt and cooperating with the eyebolt to clamp the bone screw and washer therebetween. The bone screw head and the washer include interdigitating locking means for restraining the pivoting of the screw about the axis of the eyebolt threaded stem but permitting interlocking in variable angular orientations.
