A femoral nail includes a proximal section, a distal section remote from the proximal section, and an intermediate section disposed between the proximal section and distal section and having first and second curved portions. The first curved portion is positioned closer to the proximal section than the second curved portion. The second curved portion is curved in a first plane, and the first curved portion is curved in the first plane and a second and third plane.

An implant, of intramedullary implant type, suited for securing a first bone fragment to a second bone fragment following transverse osteotomy, includes: a plate having a planar lateral face shaped to be secured to the second bone fragment, a shank shaped to be inserted into a medullary canal of the first bone fragment, and an intermediate portion, connecting the plate to the shank, the implant being characterized in that the shank is a solid of revolution centred on a longitudinal axis, the longitudinal axis being parallel to the lateral face of the plate.

A set of tools for installation of a stem implant into a bone comprises a stem-shaped priming tool (1) having a distal tip (32) and a plurality of cutting teeth (31) along a length thereof and a plurality of stem-shaped broaches (2, 3, 4, 5, 6) of different size. Each of the broaches have a distal tip and a plurality of cutting teeth along a length thereof. The priming tool (1) is shorter than, has more cutting teeth (31) per unit length, and has a sharper distal tip (32) than the smallest broach.

A tool for manipulating the position of an implantable medical device. In some embodiments the tool includes a readily releasable grasping feature that securely couples the implant to the tool while the implant is being manipulated. Preferably, the user can simply release the implant from the tool. The tool in other embodiments includes an internal pathway for accommodating non-linear implants, such as curved rods, wires, or nails. In yet other embodiments the tool has multiple handles, each handle being adapted and configured to permit manipulation of the implant in a single predetermined orientation, but with alternative handles for grasping in different hand orientations. Still further embodiments pertain to a kit having a tool and a plurality of collets, each collet being adapted and configured to grasp a different size of implant, but each collet having identical tool coupling features such that any collet in the kit can be used with the single tool. Still further, yet other embodiments pertain to tools having quick release mechanisms for the acceptance or removal of a collet, and some include external features for preventing inadvertent release of the collet when coupled to an implant.

An implant insertion assembly including an insertion handle extending from a proximal end to a distal end, the distal end including a recessed portion, an outer wall of the recessed portion having a first shape about a perimeter thereof and including an engagement mechanism. The implant insertion assembly also includes an implant extending from a distal end to a proximal end including an opening configured to receive the recessed portion of the insertion handle, the opening having a second shape configured to mechanically interlock with the outer wall of the recessed portion when the recessed portion is inserted therein to transmit torque from the insertion handle to the implant, the proximal end including a receiving structure in a wall thereof, the receiving structure being positioned and oriented to receive the engagement mechanism to removably lock the insertion handle to the implant in the axial direction.

Disclosed is an method for use of an intramedullary nail comprising a shaft having a length, a diameter, an exterior bone contacting surface, a leading (or distal) end and a trailing (or proximal) end, wherein the leading end is progressively tapered and comprises a well or cup, adapted to receive the tip of a standard K-wire, the trailing end comprises a driving fitting adapted for attachment to a driving tool for insertion of the nail into the prepared bone, the trailing end may optionally include an internal thread that can be used to secure the nail to a drill guide which can also function as an insertion handle, and the nail's shaft may also optionally be equipped with threaded and/or unthreaded cross-drilled holes for insertion of unicortical locking screws and bone screws, respectively, once the nail is placed as desired.

A bone screw extraction device includes a shaft extending longitudinally from a proximal end to a distal tip, a distal portion of the shaft including a tissue-receiving cavity extending proximally thereinto from the distal tip, the distal tip including a plurality of fingers configured to be received within a driving recess of a bone screw and a plurality of channels extending longitudinally along an exterior surface of the distal portion, each of the plurality of channels extending between adjacent ones of the plurality of fingers.

Instruments, systems and methods for using the same for correcting bone deformities in the lower extremity are disclosed. An implant insertion and removal system, including an insertion instrument that has a body portion with a handle portion at a first end of the body portion and a coupling member extending away from the handle portion to a second end of the body portion, and an engagement member rotatably coupled to the coupling member of the body portion. Specifically, instruments and systems used for hammertoe procedures are disclosed.

A rotational correction system includes an implant having first and second sections, the implant having a rotatable permanent magnet disposed in a housing of the first section, the rotatable permanent magnet mechanically connected to a nut operatively coupled to the second section. A keyed portion is interposed between the nut and one or more non-linear grooves disposed on an inner surface of the housing. An external adjustment device having at least one rotatable magnet configured to rotate the rotatable permanent magnet of the implant is part of the system. Rotation of the rotatable permanent magnet of the implant in a first direction effectuates a clockwise change in the rotational orientation of the first section relative to the second section and rotation of the rotatable permanent magnet of the implant in a second direction effectuates a counter-clockwise change in the rotational orientation of the first section relative to the second section.

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.
