A bone joint inserter device for accessing and manipulating a facet joint is provided. The bone joint inserter device improves surgical control in bone anchor location, placement, and insertion into target bone, while the inserter device also improves efficiency in engaging the target bone joint. The surgical instrument provides improved control of cutting device location and orientation, including directional control for precise bone anchor component insertion. Methods to use the bone joint inserter device in surgical procedures are also provided.

Bone joint inserter device and methods of use thereof

Spinal implants and methods for spinal stabilization and/or fusion are provided. Exemplary implants described herein can be configured for delivery to a facet joint to stabilize and/or fuse the facet joint, and can optionally be anchored within the pedicle for added fixation. The implant can optionally include a fusion-promoting bioactive material thereby providing a single device capable of spinal stabilization and/or fusion. Furthermore, a method of placing such an implant within a facet joint is provided.

Pedicular facet fusion screw with plate

Embodiments of the present invention provide methods, apparatuses, and systems for fixing dens fractures. The mode of failure for screw fixation of C2 dens fractures is often via cut-out at the anterior body. In an embodiment, securing a plate, such as a locking plate, to the anterior surface of the vertebra attached directly to an interfragmentary screw may reduce potential for anterior screw cut-out and improve construct strength. Plate supplementation of anterior screw fixation of Type II dens fractures thus improves construct strength and changes the failure mechanism from anterior screw cut-out to posterior displacement of the screw, thus improving clinical outcomes for these fractures.

Method and apparatus for dens fracture fixation

A reamer for preparing a spinal upper facet to facilitate insertion of combined screw/washer implant, preventing bone damage and facet weakening, and also allowing possibility to place grafting so as to maximize implant stabilization. The reamer has shallow outer cutting surfaces to cut a groove for spike insertion; deep inner cutting surfaces to cut a cortical-penetrating bore for insertion of the screw, and a flat therebetween to limit penetration of these cutting surfaces.
