A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.

This invention comprises a novel approach for the refixation of a loosened implant to bone, wherein the novel approach comprises providing access to a boundary region between the implant and the bone; removing abnormal interface tissue, wear debris and/or bone cement debris from the boundary region; and inserting bone fixation material into the boundary region so that the bone fixation material engages the implant and the bone and thereby effects refixation of the loosened implant to the bone.

Attachment devices and methods of using the same are disclosed. The attachment devices can be fenestrated. The fenestrations can control the flow of fluid out of and/or into the device.

A kyphoplasty cannula includes a shaft extending between opposite first and second end surfaces. The shaft includes an inner surface defining a lumen. The shaft includes a first opening that extends through the first end surface and a second opening that extends through the second end surface. A scoop extends from the second end surface. The scoop includes an arcuate surface that is continuous with the inner surface. Kits and methods of use are disclosed.

A method for treating arthritis of a joint includes identifying a bone lesion in a bone adjacent to the joint; and implanting in the bone a reinforcing member in or adjacent to the bone lesion. A kit for conducting the method includes: (a) at least one reinforcing member having a proximal face adapted to face the joint, a distal face adapted to face away from the joint, and a wedge-shaped edge adapted to pierce bone, wherein the at least one reinforcing member is planar and sterile; and (b) a container adapted to maintain the at least one reinforcing member sterile. Another kit includes: (a) a sterile fluid; (b) a syringe for injecting the fluid into a bone; (c) a curing agent adapted to cure the fluid to polymerize and/or cross-link; and (d) a container adapted to maintain the sterility of contents of the container.

The bioinjection device has a housing including a pistol grip and an elongated barrel. A trigger is pivotally mounted to the housing. An inner shaft having a distal end is slidable between a first position in which the distal end of the inner shaft is disposed in the barrel and a second position in which the distal end of the inner shaft extends past an opening in the end of the barrel. A tip containing a medicament is disposed about the opening of the elongated barrel. The tip includes at least one aperture for dispensing the medicament. One can inject the medicament from the tip into a bone fracture or degenerative bone tissue during surgery by actuating the trigger of the bioinjection device. A configurable tip may be employed to control the amount and direction of dispersion of such medicament.

Instruments and methods for delivering bone cement are disclosed herein. In one exemplary embodiment, the instrument includes a cannulated bone screw having a head that is configured to be received within a rod receiver and a shank extending distally from the head and configured to extend distally from the rod receiver, a cannulated shaft having a distal end configured to extend into the shank of the cannulated bone screw and a proximal end configured to couple to a bone cement delivery system, and a retaining sleeve disposed around at least a portion of the cannulated shaft. The head of the bone screw has proximal and distal recesses therein, and a distal end of the retaining sleeve is configured to couple to the proximal recess.

A system for delivering flowable biomaterial to an intervertebral disc space between adjacent vertebral bodies includes a delivery body defining a proximal end, a distal end spaced from the proximal end along a longitudinal direction, a cannulation extending from the proximal end to an opening adjacent the distal end, and a distal region including a tip that extends to the distal end. The distal region defines a maximum height at a location proximal of the distal end and measured along a second direction perpendicular to the longitudinal direction. The distal region is for indicating a distance between the adjacent vertebral bodies. The system includes a carrier having a longitudinaly elongate channel for carrying biomaterial and being insertable within the cannulation, as well as an advancement member configured for insertion within the cannulation to forcibly advance the biomaterial from the cannulation, through the opening, and into the disc space.

Coiled spinal implants for disc, vertebral body, and spinal motion segment replacement or reconstruction comprise a plurality of loops and spaces between the loops, with the loops formed of a hollow material and having a plurality of apertures or a longitudinal gap that extend(s) through the sidewalls of the loops and into the hollow center. The coiled implants include one or more balloons within the hollow center, the spaces between the coil loops, and/or within the central void that the coil surrounds. Filling the balloon expands the loops and thereby increases the height of the coil. Bone graft material or bone cement may be deployed from the apertures or gap.
