An intramedullary device includes an intramedullary nail extending along a longitudinal axis from a proximal end to a distal end, the nail including a channel extending longitudinally therethrough and an opening extending laterally through a wall thereof proximate the distal end, the channel including a ramped surface along a distal portion thereof opposite the opening. The device further includes a wire extending along a longitudinal axis from a proximal end to a distal end, the wire sized and shaped to be inserted into the channel of the nail such that the distal end engages the ramped surface to extend through the opening.

An expandable spacer, comprising: an axial tube having a surface, a proximal end and a distal end and a length, wherein, said surface defines a plurality of slits, said plurality of slits defining at least two axially displaced extensions, such that when said tube is axially compressed, said extensions extend out of said surface and define a geometry of an expanded spacer. Preferably the spacer is adapted to be inserted between two spinal vertebrae of a human.

Systems and methods for intermedullary bone fracture fixation are described herein. The fixation device includes a main body having a flexible state and a rigid state. The fixation device further includes a proximal interface coupled to a proximal end of the main body to anchor the fixation device to an exterior surface of the bone and a distal interface coupled to a distal end of the main body to anchor the fixation device to an interior cavity of the bone. The fixation device further includes a locking interface to configured to convert the main body from the flexible state to the rigid state.

A fixation device for providing rotation stability to a femoral neck fracture. The device includes a bone plate having at least one opening, a compression screw housing extendable through the opening of the bone plate, a compression screw being at least partially disposed within the bore of the housing and selectively moveable through the bore, and a collapsible and expandable anchoring member coupled to the compression screw. The anchoring member is configured to transition between a collapsed condition and an expanded condition upon advancement of the anchoring member from the compression screw housing to rotationally stabilize the compression screw within a femur.

A bone implant comprising an elongate body having a first end and a second end coupled by a shaft is disclosed. The first portion is configured to couple to a first bone. The second portion comprises a first expandable section comprising at least one expandable feature. The first expandable section is configured to be received within a reverse countersink in a second bone in a collapsed state and to expand within the reverse countersink. The expandable feature couples to a bearing surface of the reverse countersink. A surgical tool comprising a shaft and at least one expandable cutting edge is disclosed. The shaft is sized and configured to be received within a canal formed in a bone. The expandable cutting edge is formed integrally with the shaft. The expandable cutting edge is configured to expand from a collapsed position to an expanded position for forming a reverse countersink.

According to some embodiments, an implant for correcting a deformity in or near a joint of a subject includes an implant body having an internal lumen, a suture side hole or window extending through a wall of the implant body and providing access to the internal lumen through an exterior of the implant body, a tension assembly comprising a first bone anchor and a second bone anchor, wherein the first and second bone anchors are configured to be placed on opposite sides of the implant body, and an adjustable suture loop coupling the first bone anchor to the second bone anchor, wherein at least a portion of the at least one adjustable suture loop is positioned within the internal lumen of the implant body.

A bioabsorable stent is disclosed. The stent is made of a polymer and/or non-polymer material and has an elongated body having a proximate end, a distal end, and at least one open channel formed on the exterior surface of the elongated body to provide fluid communication between the proximal end and the distal end. Also disclosed is a bioabsorable stent having an elongated center rod having a proximate end and a distal end and a plurality of leaflets extending outward from the center rod and forming channels between two neighboring leaflets to provide fluid communication between the proximal end and the distal end.

Small bone surgical nail devices and methods for use in small bone fracture surgeries, for example, clavicle fracture surgery. The systems and methods can include a nail device with specific design features including but not limited to differing designs, geometries, and configurations in multiple zones of the device, an associated optional end cap, and/or optional locking screws.

A system and method for forming a hip implant offering minimal invasiveness is described. The system comprises means for positioning the implant under optical and X-ray control, an implant and an applicator for screwing and expanding the implant. The implant includes an insert body and an expansion tube with cut-outs and slits defining legs. The legs expand radially through windows in the insert body when the expansion tube is pushed against the sloped distal portion of the insert body. The expansion process may be ensured by using an anti-rotation device to prevent the insertion tube from rotating within the insert body. Applicator and implant are provided with means preventing cold welding during the implantation process.

A bone anchor includes: a main body defining a longitudinal axis and including a head; at least one insertion hole which extends from a first opening formed in the head to a second opening formed in the main body, the at least one insertion hole having an axis which is arranged to be inclined with respect to the longitudinal axis of the main body at an angle, and the insertion hole being configured to receive and guide therethrough a pin-shaped element to be anchored within a bone or bone fragment; and a locking device configured to lock the position of the pin-shaped element inserted within the at least one insertion hole in an axial direction.
