The invention relates to a plate fixed between two bone parts by way of screws engaged in holes formed in the thickness of said plate. The plate comprises an angled member or rib which is inclined according to an angle of between about 30° and 60° in relation to the plane defined by the plate. The angled member or rib has a hole for engaging a screw and is located in the central part of the width, over a determined part of the length of the plate, so that the screw brings the two bone parts into a compressive position.

There is a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, comprising a bone plate portion including an outer surface, an inner surface and at least one fixation aperture extending from the outer surface to the inner surface and a bone wedge portion extending from the plate portion at a first end and a free opposite end, the bone wedge portion comprising a porous architecture configured to promote bone ingrowth, the wedge portion defining first and second engagement surfaces for engaging the first bone segment and a second bone segment, respectively. There is also a method of manufacturing a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, a method of promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, and a fixation kit.

An interfragmentary guide and plate system is described.

A surgical assembly, a stabilisation plate and methods are disclosed. The surgical assembly comprises: a jig (100) comprising a body having a tissue-engaging surface shaped to be received by tissue to be re-orientated by a correction factor, said body defining a plurality of alignment apertures, said plurality of alignment apertures being orientated to be parallel with respect to each other on application of said correction factor. In this way, it is possible to determine from the jig itself when the desired correction factor, rotation or displacement has been applied correctly because the alignment apertures become parallel, thereby avoiding the need for additional operative measurement and/or imaging.

Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.

A bone positioning guide may be used as part of a bunion correction procedure. The bone positioning guide can include a bone engagement member configured to be positioned on a medial side of a first metatarsal of a foot and a tip separated from the bone engagement member by a distance effective to position the tip on a lateral side of a second metatarsal and in an intermetatarsal space between the second metatarsal and a third metatarsal. The bone positioning guide can also include a mechanism operable to reduce the distance between the bone engagement member and the tip, thereby causing the first metatarsal to move in at least a transverse plane to reduce an intermetatarsal angle between the first metatarsal and the second metatarsal.

A device for fixation of inner and outer bone fragments comprises at least three fixation means (5), at least one tilting preventing means (6) and a securing plate (7). The fixation means (5) are configured to allow, during secondary compression of the inner and outer bone fragments (2, 3), a sliding movement of the fixation means and said outer bone fragment relative to one another and thereby an interruption of an engagement of the securing plate (7) with the outer bone fragment (3) without affecting the angular position of the fixation means relative to the securing plate and relative to one another. The tilting preventing means (6) is configured to allow, during said secondary compression, a sliding movement of the at least one tilting preventing means and said outer bone fragment (3) relative to one another and thereby an interruption of the engagement of the securing plate (7) with the outer bone fragment. The tilting preventing means (6) is also configured to prevent or counteract tilting of the device.

Disclosed is a system and method for fusing two bones within a mammal. More particularly described is such a system and method for a transcortical fusion system wherein which a plate is affixed in a longitudinal slot or aperture cut into the anterior portion of the tibia and the talus, thereby achieving a fusion of the joint while placing the fusion site in the joint in compression.

The self-contouring plate for bone fractures allows a surgeon to bridge a bone fracture, primarily in bones of complex shape where the use of plates or screws is difficult. The self-contouring plate is formed from a series of similar or identical rigid elements, the elements able to bend and rotate with respect to each other. This flexibility is initially helpful as the surgeon contours the device to the shape of the bone. When the desired shape is reached, the elements are locked into place. The length of device is adjusted by adding or removing elements, much like a necklace. Each element of the self-contouring plate includes a ball that extends away from a body, a cavity for receiving the ball of the neighboring plate, and a screw to compress the ball within the cavity.
