Abstract: A cavity drill is provided, which is configured for use with a bone drill. The cavity drill includes a body. The bone drill has a first portion movably connected to a second portion. A third portion is movably connected to the second portion. The body is mounted with the third portion of the bone drill. A sheath extends from the third portion to a distal end. A curette is connected with the distal end of the bone drill. The curette is composed of retractable cutting tines/blades which are turned/powered by the bone drill motor. The curette tines can be used in a partially or fully deployed state and at low or high speed. The curette is designed to create cavities of varying size in a bone. The cavity drill and the bone drill may include a radiation protection guard and radiolucent portions. Methods of use are also provided.

Abstract: A radiolucent bone drill and/or impact drill is provided, which includes a first portion connected to a second portion. The first portion defines a first axis and the second portion defines a second axis. The second axis is disposed at an angle relative to the first axis. A third portion is connected to the second portion. The third portion has a shaft extending therefrom. The shaft includes a distal end configured to engage bone. The bone drill may include a radiation protection guard mounted to the first portion. Specific drill bits, access sheaths/conduits/tube, curettes, and screwdriver bits designed to be used with the devices are provided. The bone drill may be used to place an access sheath/conduit/tube/needle into a bone in a single step. Methods of use are also disclosed.

Abstract: A self filling autograft bone screw for stabilizing and fusing bones within a body of a patient. The self filling autograft bone screw includes an elongated body member, a lumen disposed within the elongated body member, a plurality of external threads, a cutting section, and at least one opening disposed along the length of the elongated body member. A system and method for inserting a bone screw into a bone of a patient's body includes advancing and positioning a self-filling bone screw including an elongated body member, a lumen disposed within the elongated body member, a plurality of external threads, a cutting section, and at least one opening disposed along the length of the elongated body member into a bone within a patient's body.

Abstract: Percutaneous interbody spine fusion devices are provided. These devices may have a number of different designs and exemplary features. One device consists of a single rotating hollow cam cage with perforations (with or without fixation anchors) and a delivery tool. Another device consists of a counter-rotating cam cage (with or without fixation anchors) and a delivery tool. A third device consists of an expanding cam with anchors and delivery tool; this device may consist of a single expanding cam or a series of expanding cams. A delivery tool is included. A fourth device consists of a spring cage; this device may be a stand-alone device, can be combined with expanding cam device, and may be incorporated into a cage. A delivery tool is included. This spring cage may or may not have fixation anchors. A fifth device consists of a random coil support device that can be used as a nuclear or spine fracture support device; a delivery tool is included.
