A bone support fixating device with a longitudinally slotted hip screw which permits operative compression of the fracture and holds this compression yet allows sliding as further compression of the fracture occurs under forces of weight bearing; comprising a hollow cylindrical shaft with a screw portion at its upper proximal end and four equally spaced longitudinal grooves at its lower distal end, having three equally distant angled holes between the ends, through which three wires can be inserted, the three elastic proximally curved wires, welded, glued or crimped distally, can be inserted into the hip screw collectively called the tri-wire; The proximal end has the wires curved outward, with all three wires equally spaced; upon pushing the tri-wire into the hip screw, the wires goes through the angle holes in the hip screw and provides three projections equally spaced; which improves the rotational stability of the proximal fracture fragment.

The present application relates to repair systems, and more particularly to fifth metatarsal repair systems and methods of use. The repair systems described herein can include a fixation device with a threaded section. The repair systems described herein can include one or more grippers designed to be deflected outward to grip the sidewalls of an intramedullary canal of the fifth metatarsal. The repair systems described herein can include an end cap. The end cap can include a fastener including thread designed to engage the threaded section of the fixation device. The end cap can include a cap designed to move relative to the fastener.

Apparatus for generating, applying and maintaining compression to a site in a human or animal body, the apparatus comprising: a staple comprising: a bridge configured to be elastically bendable; a first leg connected to the bridge by a first hinge region configured to be elastically bendable; and a second leg connected to the bridge by a second hinge region configured to be elastically bendable; wherein the first hinge region comprises a first hole configured to mate with a first element of a delivery device and the second hinge region comprises a second hole configured to mate with a second element of a delivery device; and wherein the first and second legs are angled toward one another when they are in an unstrained state; whereby, when the staple is mounted to a delivery device so that the first hole of the first hinge region mates with a first element of a delivery device and the second hole of the second hinge region mates with a second element of a delivery device, and when the delivery device applies a force to the bridge of the staple so as to reconfigure the bridge of the staple, the first and second legs are pivoted away from one another toward a parallel disposition.

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 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.

In one embodiment, the present invention includes an intramedullary osteosynthesis or arthrodesis implant including a central body, a first pair of legs extending from the central body to a pair of leg tips, and a second pair of legs extending from the central body, in a direction opposite the first pair of legs, to a pair of leg tips such that the central body, first pair of legs and second pair of legs are positioned alongside a longitudinal axis.

Silver and/or zinc ion releasing implants, systems and method of operating, inserting and activating/inactivating them are described. In some variations the implant is configured as a bone implant that includes a bone-screw or intramedullary rod like body configured to receive a treatment cartridge having a plurality of ion-releasing members configured as an anode that can controllably engage with a catheter to turn galvanic release of ions on/off as desired. These devices may be configured to release silver ions (and/or zinc ions) above a predetermined level for a predetermined period of time and may maintain a concentration of ions over a relatively large volume of tissue. The ion-releasing members may be configured to reduce or prevent implant movement.

Bone anchor assemblies and related instrumentation are disclosed herein. In some embodiments, a modular bone anchor assembly allows for a bone anchor to be driven into bone and a head or receiver member to be attached thereto at some later point in time. The bone anchor can have a smaller footprint than the complete assembly, which can improve visualization and anatomical spatial awareness during insertion of the bone anchor and during other surgical steps performed prior to attaching the head or receiver member to the bone anchor. A variety of modular head types are disclosed, as are various instruments for driving a bone anchor, attaching a head to a bone anchor, removing a head from a bone anchor, and making a unilateral attachment to a head of a bone anchor assembly. Drive interfaces for driving a bone anchor are disclosed, as are features that allow a bone anchor to act as a fixation point for soft tissue retraction, disc space distraction, derotation, and the like.

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.

A staple comprising: a bridge configured to be elastically stretchable; a first leg connected to said bridge and configured to be elastically bendable; and a second leg connected to said bridge and configured to be elastically bendable; said first and second legs being connected to said bridge so that they are angled toward one another when they are in an unstrained state; such that when said bridge is elastically strained into an elongated condition, and said first and second legs are elastically strained so that they extend substantially parallel to one another, and said first and second legs are disposed in appropriate holes on opposing sides of a fracture line, and when the strain on said staple is thereafter released, compression will be provided across the fracture line by both said bridge and said first and second legs.
