Abstract: A surgical guide device can be attached to a patient's bone for assisting an open wedge osteotomy. This device includes two parts which are joined together by way of removable securing unit, namely: a proximal part, including a lower border defining at least one portion of the upper edge of a guide window, and a distal part having an upper edge defining at least one portion of the lower edge of the guide window. The proximal and distal parts are each provided with a plurality of through holes adapted for receiving members temporarily implantable in the bone and/or adapted to guide a drilling of holes in the bone. The arrangement of the through holes of the surgical guide device advantageously takes into account the planned open wedge osteotomy and anticipates the final position of the screw locations of the reported osteosynthesis plate for freezing the two bone fragments.

Abstract: Disclosed is an accessory for bone surgery, advantageously for operative arthroscopy, suitable for positioning and attaching a bone fragment on a target bone surface. This accessory includes a body of a sighting body including at least one sighting hole which opens on the two end faces, and a feeler member, extending in protrusion from the front end face of the sighting body. A front end face of the sighting body and a lower face of the feeler member together form a dihedral receiving surface against which the bone fragment is intended to bear. This accessory also includes pressing element capable of temporarily maintaining the bone fragment bearing against the dihedral receiving surface.

Abstract: In an osteosynthesis device with a plate and a screw for fixing the plate on a bone, the head of the screw includes a thread for its locking with the internal thread in its receiving hole. The internal surface of the plate hole includes a first frustoconical section that extends at an angle 30-60° with respect to the hole central axis, and a second frustoconical section that extends between the first frustoconical section and the plate lower face, at an angle 8-12° with respect to the hole central axis. The internal surface of the hole also includes at least three upper undercuts, and at least three lower undercuts, which upper and lower undercuts allow a degree of freedom in angulation of the screw, and also preserve a portion of hole internal thread on all the generatrices of the hole internal surface located in planes parallel to the central axis.
