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.

Transforaminal intersomatic cage for an intervertebral fusion graft and an instrument for implanting the cage

A vertebral support device () is disclosed, which in various embodiments comprises at least two osseous anchoring implants (), each designed to be anchored to a vertebra, and at least one linking element () fixed to the osseous anchoring implants () by fasteners () that maintain a fixed angle between the longitudinal axis (L) of the linking element () passing through rigid elements () of the linking element () and the insertion axis (DV) of the implants (). The linking element () includes at least one elastic dampening element () that that allows the implant-bearing vertebrae some freedom of movement. The dampening element () accommodates the stresses imposed on the linking element () during movement of the vertebrae and tends to return the support device () to its normal configuration.

Vertebral support device

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.

System and method for performing vertebral reduction using a sleeve

This present invention concerns 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 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.

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.

Interbody spacer

Embodiments described herein provide tools and methods for spinal fusion procedures. One embodiment of a tool can be a pedicle access tool that performs the functions of targeting needle, cannula, tap and awl. The cannula of the tool can be used to guide various tools and bone graft or fusion promoting material to a surgical site for a spinal fusion procedure, such as a posterolateral procedure. In other embodiments, a k-wire can be used as the guide.

Fusion method and pedicle access tool

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.

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.

Pseudo arthrosis device

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.
