Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.

A bone anchoring element comprising a shaft (2) for anchoring in a bone, with a plurality of barb elements (7) arranged in at least one helical line around the shaft axis (M) is described, wherein said barb elements are elastically movable relative to the shaft. The bone anchoring element (1) is easy to press into a core hole bore in a bone. The barb elements (7) act in a similar manner as do the threads on a conventional bone screw and thus provide for depth positioning. Moreover, the barb elements at the same time secure the bone anchoring element and prevent it from sliding-out.

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 (100) and device (300) for mounting and tracking a tracker array during a surgical procedure are described. For example, the system includes a surgical navigation system (700) including a position tracking system (702) configured to track one or more tracker arrays, and a device (300) for mounting a tracker array (306) onto a patient during the surgical procedure. The device includes an intramedullary (IM) canal component (304) configured to be inserted into an IM canal (310) within a bone (312). The device further includes a tracker pin (308) configured to penetrate at least a portion of the bone and engage an inserted end (411, 413) of the IM canal component, and a tracker array (306) affixed to the tracker pin. The IM canal component is configured to engage the IM canal of the bone to stabilize the tracker array during the surgical procedure.

An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.

A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

This disclosure relates to a bone tamp and a corresponding method including the bone tamp sliding over a guide wire projecting from a digit of a foot and protruding from an interphalangeal implant.

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.

An intramedullary nail is suggested comprising a nail shaft with a lateral recess, with an expansion element being arranged in that recess, and an adjustment screw for adjusting the position and orientation of the expansion element relative to the nail shaft. A threaded bore may be formed in the nail shaft, wherein the threaded bore extends through the nail shaft and into the recess and is adapted to receive the adjustment screw.
