Invention is related to the nails used in the surgical treatment of humeral fractures. And it is characterized with, humerus internal safe locking nail (1) which is including; Locking pin (2) providing distal locking by outgoing from the distal hole of the nail (8) in pursuit of being screwed inside all along from the proximal of the humerus internal safe locking nail (1) At least one locking sending slot (3) on the locking pin (2) providing locking pin (2) to be sent to lock from the distal part At least one locking pin slot of the nail (5) on the proximal part of the humerus internal safe locking nail (1) providing locking pin (2) to proceed into humerus internal safe locking nail (1). At least one Threaded proximal part of the locking pin (11) on the locking pin (2) At least one threaded end of the locking pin (7) locking by outgoing from the distal hole of the nail on the locking pin (2) At least one Bone entering tip of the locking pin (9) providing locking by entering to the bone angularly on the threaded end of the locking pin (7) Anatomically angled tip on the distal part of the nail (10) in the form of curved and straight comprised on the distal part of the humerus internal safe locking nail (1). humerus internal safe locking nail (1) is characterized with humerus internal safe locking nail (1) including rotation preventive end structure of the nail (12) on the distal part.

A surgical implant which includes: a first anchoring portion comprising two first arms movable between an inserting position and an anchoring position, in which the first arms are spread apart so as to be anchored in a first bone; a second anchoring portion to be anchored in the second bone; and an intermediate portion connecting the first anchoring portion to the second anchoring portion. The intermediate portion comprises: a recess; and a first connecting portion and a second connecting portion that are remote from one another. Bringing the first connecting portion and second connecting portion closer together moves the first arms from the inserting position thereof to the anchoring position thereof.

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.

The present invention is generally directed to intramedullary nails that can include a keel configured for rotational stabilization and/or a multi-sectioned rod configured to apply compression to a fracture.

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.

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 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.

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.

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.
