A device for forcefully inserting a surgical implant in a recipient bone by impaction, comprising an impactor (10) that exerts an impaction force on the implant and is associated with at least one sensor (12). The sensor (12) measures a value from among the exerted impaction force and the deformation of the impactor (10) and provides a measurement signal representing the temporal variation of said value during an impact. The sensor (12) is connected to a processing unit (30) that is configured to compute, on the basis of the temporal variation of said value during the impact, an indicator representing the level of contact between the implant and the recipient bone. The indicator corresponds to the duration separating the instant corresponding to the first maximum amplitude peak of the measurement signal from the instant corresponding to the second maximum amplitude peak of the measurement signal. The implant can be a femoral rod (2).

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end of the intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail.

Orthopedic systems and methods for installing an implant and/or boring a bone bicortically. The system may include a drill having a proximal boring portion configured to bore a larger hole in a bone more efficiently when the drill rotates in a first direction compared to an opposite second direction, and a distal boring portion configured to bore a smaller hole in the bone more efficiently when the drill rotates in the second direction. The implant may be configured to be implanted at least partially in the bone, such that a first region of the implant is located in the larger hole and a second region of the implant is located in the smaller hole. In an exemplary method, the larger hole and the smaller hole may be bored in the bone's near cortex and far cortex, respectively, by a shaft and a nose of the drill rotated in opposite directions.

The present invention relates to an improved orthopaedic device for athrodesis, in particular for the arthrodesis or fusion of a joint, for example an ankle joint, of the type comprising of a nail having head and tip ends opposed to each other; at least a first portion of the nail having an axis of symmetry; a single circular first transverse hole made in the first portion near the head of the nail and extended according to its own axis perpendicularly to the axis of symmetry; a slotted second transverse hole still made in the first portion of the nail and extended perpendicular to both the first axis of symmetry; and to the axis of the first transverse hole; and the slotted second transverse hole being made at a greater distance with respect to the head of the nail than the distance from the head of the first transverse hole.

A system and method for targeting a feature on a surgical device, includes a shape sensing element coupled to a surgical device. A guide system having a moveable guide aperture is coupled to the surgical device in communication with the shape sensing element. An interrogator is operable to poll the shape sensing element for information related to the deflection of the targeted feature coupled in communication with a portion of the shape sensing element. A data processor is operable to communicate with the interrogator and provide adjustment information to the user related to the change in shape of the shape sensing element, which is related to a translation of the guide aperture with respect to the first device end such that the guide axis is aligned with the target axis. The shape sensing element may comprise at least one optical fiber, which may comprise a set of Bragg Gratings.

The combination of: a) an implant having a body with a leading end and a trailing end and external threads extending around a lengthwise axis, the body having an axial through passage and configured to be directed into a bone passage whereby upon turning the body in a first direction around the lengthwise axis, the external threads engage a surface bounding the bone passage and cause the implant to be advanced in an assembly direction into an operative position; and b) a removal tool with a first component that is configured to be engaged with the body with the implant in the operative position in such a manner that the body will follow movement of the first component as the first component is: a) turned in a direction opposite to the first direction; and b) drawn in a direction oppositely to the assembly direction to thereby allow the implant to be separated from the bone.

Telescopic nail (2) for the treatment of fractures or deformations of long bones, as for example in the case of osteogenesis imperfecta or pseudo-arthrosis. comprising: a hollow stem (2); a rod (10) telescopically inserted into said hollow stem (2); a first fastening element (20) coupled to an end of said hollow stem (2) for fixing to a first long bone end; a second fastening element (30) coupled to an end of said rod (10) for fixing to a second long bone end.

Advantageously, one end of said hollow stem (2) is provided with coupling means (40) for coupling to an end of a tool which can be inserted into a cavity formed in the bone for insertion of the nail.

A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.
