Disclosed are devices and methods for stabilizing first and second bone portions relative to one another. In one example, implants, instruments and methods are provided that can be used with minimal exposure of the fractured bone and along curved path.

A targeting system for aligning an axis of a targeting sleeve and a bore in a distal end portion of an intramedullary nail is proposed, the targeting device comprising a distal targeting arm with a first end being configured to be coupled to a trailing end of an intramedullary nail, an adjusting device, the adjusting device being configured to be coupled to the distal targeting arm. The adjusting device may comprise an adjusting element and a nail follower including two targeting holes each being configured to receive a sleeve assembly. The adjusting element may cooperate with the nail follower such that the positions of the two targeting holes are adjustable so as to correspond to respective locking holes at a leading end of the intramedullary nail, even when the nail is bent.

Examples of devices and methods for stabilizing a fracture in a bone include a body having an elongate distal portion having an outer surface defining a screw thread and an elongate proximal portion having a non-threaded outer surface.

There is disclosed a device and method for stabilizing a bone. The device includes a flexible threaded portion operable to thread along a curved path in a bone.

The invention relates to a medical instrument for putting pins (2) into place, the instrument comprising: at least one rectilinear pin (2) presenting a determined length and a determined diameter; an insertion trocar (5) comprising a guide sheath (6); a guide (10) for a pin (2) the guide comprising a flexible tube (11) presenting an outside diameter less than the inside diameter of the sheath to enable it to be inserted in the sheath, the flexible tube (11) presenting between its distal end and its proximal end a length that is greater than the length of the pin; and a positioner (13) for positioning a pin (2), the positioner comprising an obturator (14) possessing an outside diameter less than the inside diameter of the flexible tube (11) in order to enable it to be inserted in and to slide inside the flexible tube.

The invention relates to a resorptive intramedullary implant between two bones or two bone fragments. The implant includes a single-piece body (1) having a generally elongate shape and having, at each end, areas for anchoring to the bone portions in question, characterized in that one of said areas (A1) has a cylindrical cross-section while the other area (A2) has a flat cross-section.

An intramedullary nail system is provided with at least one resilient, elongate nail body configured to extend axially along a medullary bone cavity, and at least one bone anchor. The bone anchor includes a distal bone engagement portion configured to secure the anchor to a bone, a proximal nail engagement portion configured to receive a portion of the nail body therethrough, and a tightening mechanism configured to move from a movable state in which the nail body may slide axially and rotate through the engagement portion and a fixed state in which the nail body is prevented from moving relative to the engagement portion. Methods of use and surgical kits are also provided.

Implantable devices for fixation of curved bone such as the pelvic ring pubic symphysis and acetabulum, and methods for the use of the devices are disclosed. The implantable devices are convertible between a flexible state and a rigid state, and include an elongate structure having a proximal bone interface, a main body, and a distal bone interface. In a flexible state, the devices may be inserted along, and conform to a curved pathway, and in the rigid state, the devices may support the mechanical loads required to fixate a fracture.

Devices and methods for repairing bone fractures are described herein. A pin directing device for steering a flexible bone screw is disclosed. A fluted entry tool for penetrating into cancellous bone without penetrating the far cortex of the bone is disclosed. A flexible bone screw having a rotational position marker positioned thereon at a terminal twenty-five percent of the shaft is disclosed. A flexible bone screw comprising at least eighty percent cold work hardened alloy is disclosed. A pin bending clamp having a transverse hole in the jaws is disclosed. A flexible bone screw with a cortex climbing thread portion at the tip, which is helicoid, is also disclosed.

A targeting system for aligning an axis of a targeting sleeve and a bore in a distal end portion of an intramedullary nail is proposed, the targeting device comprising a distal targeting arm with a first end being configured to be coupled to a trailing end of an intramedullary nail, an adjusting device, the adjusting device being configured to be coupled to the distal targeting arm. The adjusting device may comprise an adjusting element and a nail follower including two targeting holes each being configured to receive a sleeve assemply. The adjusting element may cooperate with the nail follower such that the positions of the two targeting holes are adjustable so as to correspond to respective locking holes at a leading end of the intramedullary nail, even when the nail is bent.
