Abstract: This disclosure presents various embodiments of a transforaminal intersomatic cage for an intervertebral fusion graft, and an instrument and method for implanting the cage, an embodiment of the cage having a body in the shape of a circular arc and comprising a lateral concave surface, a lateral convex surface, a straight upper surface, a straight lower surface and an end wall having at least one hole, called the end hole, designed to receive a rod of an instrument for implanting the cage between the vertebrae, wherein: the end hole has an orientation that is more or less tangential to the circular arc described by the body; the extremity opposite to the end wall of the body includes a return part extending the body toward the center of the circle on which the circular arc described by the body lies.

Abstract: Embodiments described herein provide systems and methods for vertebral reduction using sleeves detachably coupled to collars of bone fasteners. The reduction can be performed during a minimally invasive procedure for implanting spinal stabilization systems. A sleeve can include internal threads that match threads on the respective collar to form a continuous set of threads. Threads on a closure member can be engaged with the threads on the sleeve and the closure member turned to translate the closure member along the sleeve. The closure member can be used to push a rod relative to the collar to which the sleeve is attached to cause a vertebral body to move.

Abstract: An intervertebral or spinal implant having a spacer, a cage, and a locking mechanism, where the locking mechanism may be configured to facilitate a connection between the spacer and the cage. In some cases, the spacer may include a distal end wall, a proximal end wall, a first lateral wall, and a second lateral wall, where the locking mechanism may be situated at the proximal end wall adjacent a receiving opening in the proximal end wall. The implant may have one or more spikes extending from a top and/or a bottom of the spacer to facilitate stabilizing the implant between vertebrae after insertion of the implant in the spinal column.

Abstract: A pneumatic or hydraulic massage sock including a unitary molded insole formed with one or more internal pump chambers for generating fluid pressure throughout the user's gait, and a plurality of interconnected compression pads each containing an array of fluid feed tubes. The compression pads fold up and around the foot and calf substantially enveloping them in a low-profile sock-like configuration. An outer shell is worn overtop to maintain the compression pads against the user's calf. The fluid feed tubes are in fluid communication with the pump insole to provide a self-compressive non-constricting deep-kneading, undulating (wavelike) pattern massage action up the leg in accordance with the full-length heel-to-ball-to-toe foot plant. The massage sock appears as a conventional sock so it can be worn with virtually any conventional pair of shoes. This provides effective unobtrusive relief for individuals with circulatory disabilities, diabetes, arthritis, etc.

Abstract: A bone anchor for use in conjunction with orthopedic spinal fixation comprising a pedicle screw having a threaded proximal tip for threaded insertion into a hole prepared into a vertebral body through the pedicle of the vertebra from the posterior approach. The shank of the anchor is of smaller diameter than the proximal tip so as to receive a sleeve after insertion into the bone. The tubular sleeve is provided with a plurality of longitudinal slots evenly arranged about the longitudinal axis of the sleeve to forming a plurality of longitudinal. A tubular compression collar for insertion over said shank portion is provided on the shank and driven toward the proximal tip compression the sleeve and causing the ribs to expand radially into a star pattern securing the anchor in the bone. A tubular collar of natural or synthetic bone growth promoting material may be inserted to promote bone growth, close the hole and further stabilize the anchor.

Abstract: A pneumatic or hydraulic massage sock comprised of a unitary molded insole formed with one or more internal pump chambers for generating fluid pressure throughout the user's gait, and a plurality of interconnected compression pads each containing an array of fluid feed tubes. The compression pads fold up and around the foot and calf substantially enveloping them in a low-profile sock-like configuration, and an outer shell is worn overtop to maintain the compression pads against the user's calf. The fluid feed tubes in the compression pads are in fluid communication with the pump insole to provide a self-compressive non-constricting and yet deep-kneading, non-constricting undulating (wavelike) pattern massage action up the leg in accordance with the full-length heel-to-ball-to-toe foot plant. The outer shell hides the pump insole and compression pads and looks like a conventional sock, such that the combination can be worn with virtually any conventional pair of shoes.

Abstract: A pneumatic/hydraulic massage sock comprised of a web of hydraulic/pneumatic tubes connected to a pump in the sole of the sock. The over-the-calf web comprises a spiral web of interconnected flexible tubes. The web of tubes is encased in a fabric shell that generally conforms to the foot and calf and is worn like a sock. Mere walking produces a cumulative pump force to inflate/constrict the upper web in cyclic patterns to promote an effective kneading-pattern massage. The massage sock provides effective relief for individuals with circulatory disabilities, diabetes, arthritis, etc. They would offer mild, non-constricting variable pattern-compression and yet are non-intrusive and maintain a low-profile.

Abstract: A pseudo arthrosis device disposed in a patient between two adjacent vertebrae. The device has an enclosure with a plurality of compressible flexible members packed longitudinally therein. The enclosure is attached to at least one of the adjacent vertebrae. A method of use is disclosed.

Abstract: A pseudo arthrosis device may be placed in a disc space to provide support for adjacent vertebrae. The device may have an enclosure formed from a flexible, permeable material. A plurality of elongated members may be packed longitudinally in the enclosure. The elongated members may be compressible and/or flexible. In certain embodiments, elongated members may be solid rods and/or hollow tubes. A plurality of spaced-apart perforations may be formed in solid and hollow elongated members. The enclosure may be placed in an intervertebral space between the adjacent vertebrae such that the elongated members are disposed longitudinally between the adjacent vertebrae. The pseudo arthrosis device may include a tab designed to couple the enclosure to an adjacent vertebrae.

Abstract: A drill and tap tool may be used to form threaded openings in bone. The tool may include a shaft that has a drill section located at an end of the shaft. A tap section may be located adjacent to the drill section. The drill section may include a drill point for initiating an opening in a bone. A drill bit section may abut the boring tip, and a tap section may be adjacent to the drill bit section. The drill bit section may be configured to form an opening in the bone. A diameter of the opening formed by the drill bit section may be substantially the same as the shaft diameter of the screw to be inserted in the threaded opening formed by the drill and tap tool.
