An example method includes: (a) accessing a medullary canal of a rib having a fracture, (b) advancing a guidewire into the medullary canal across the fracture, (c) advancing a delivery catheter containing a stent over the guidewire into the medullary canal and across the fracture, (d) retracting the delivery catheter relative to the stent, and (e) expanding the stent in the medullary canal.

A device including a first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint opposite the first bone structure; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force along an axis between the first plate and the second plate so as to urge the first plate and the second plate away from one another, wherein the device is configured so as to have a range of motion ranging from a minimum distance between the first plate and the second plate to a maximum distance between the first plate and the second plate, and wherein the mechanical actuation mechanism is configured such that the distraction force is substantially constant distraction force across the range of motion.

The invention relates to a system (10) for the intraosseous injection of surgical cement comprising an external sleeve (11); a cannula (13) mounted coaxially in the external sleeve, said cannula being able to be moved along a longitudinal axis (A) in the external sleeve, the cannula being provided with a tapered distal point (15); and a stent (18) accommodated in the interior of the external sleeve, said stent being mounted around a distal end (16) of the cannula. The invention also relates to a kit comprising a system of this type for the injection of surgical cement, surgical cement injection means capable of being connected to the proximal end of the internal cannula, and possibly surgical cement.

The invention relates to an assembly (1) for positioning and positionally immobilizing an inflatable balloon (3) within a vertebral body, comprising an access piece (2) providing access to the vertebral body, which has a cannula and is of elongate shape, and an inflatable balloon (3) mounted at the end of a catheter (4) able to be connected to a fluid-delivery unit, the assembly comprising balloon (3) and catheter being designed to pass slidingly through the access piece (2), characterized in that the access piece (2) comprises means of anchorage in the vertebral body, the assembly further comprising means for positionally immobilizing the catheter provided with the balloon (3) on the access piece (2).

A device including a first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint opposite the first bone structure; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force along an axis between the first plate and the second plate so as to urge the first plate and the second plate away from one another, wherein the device is configured so as to have a range of motion ranging from a minimum distance between the first plate and the second plate to a maximum distance between the first plate and the second plate, and wherein the mechanical actuation mechanism is configured such that the distraction force is substantially constant distraction force across the range of motion.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

An implantable, expandable bone support device for a bone, such as a vertebra. The device has a pre-shaped bulk block for filling up an intra-osseous implant cavity of the bone. The pre-shaped bulk block is movable to project in an expanded state of the device out relative to a non-expanded shape of the device. The block comprises a load supporting surface for supporting a load acting on the bone, and a fixation interface for interfacing with a pre-shaped fixation which when interfacing holds the pre-shaped block in the expanded state of the bone support device in position, against the load, and inhibits the device from collapsing from the expanded state into the non-expanded state. An actuator interface allows engaging with an actuator for actuating the movement of the bulk blocks along the pre-defined path. The device comprises a guide defining the pre-defined path along which the bulk block is movable.

The present invention relates to a spacer intended to be introduced between two elements of a vertebral body. This spacer comprises a tube, a spacer module and an actuating system of the spacer module, the actuating system comprising at least one rod which is, on one hand, accessible from a distal end of the tube and, on the other hand, connected to said spacer module. The spacer is characterized in that the spacer module comprises two blades coplanar to a longitudinal axis of the rod, these blades being movable between a closed position in which the blades are substantially parallel to the longitudinal axis of the rod, and a deployed position in which the blades have an arched shape, and in that in their deployed position, these blades are asymmetrical with respect to each other and with respect to said longitudinal axis of the rod.

The apparatus, systems and methods disclosed herein generally relate to the surgical repair or alteration of bone. More particularly, certain of the disclosed apparatus, systems and methods of the present disclosure relate to the use of a directionally-reinforced composite material to emulate anisotropic structural characteristics of an original anatomic trabecular structure. The directionally-reinforced composite material may generally include a scaffold set in a composite matrix, wherein the scaffold determines the anisotropic structural characteristics of the materials. In some of the embodiments, a scaffold may include at least a first plurality of struts which are generally aligned in a first direction and a second plurality of struts aligned in a second direction.

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.
