摘要： An expansion and compression instrument for fracture fixation includes a first handle member, a second handle member, a bearing assembly, and a replaceable tip insert. The bearing assembly axially receives a driver. The replaceable tip insert is adapted to engage an aperture of a fracture fixation plate. The driver is adapted to engage the head of a bone screw, partially threaded into bone proximate the fracture and disposed through a longitudinal slot of the plate. Manual manipulation of the handle members together or apart causes the driver head and replaceable tip insert to become farther apart or closer together, respectively. Pivotal or hinged attachment of the bearing assembly to a handle member permits pivotal movement of the driver relative to the handle member and permits the jaws of the replaceable tip insert to remain in substantial engagement with the fracture fixation plate during expansion and compression.

摘要： A bone fixation plate for fixation of fractures having a small terminal bone fragment, such as fractures of the distal radius. The plate includes an elongated body, and two hook members extending from a first end of the elongated body. A contoured region is configured to approximate the surface contour of the distal radius proximate the volar rim, the dorsal rim, or the radial arm. Each hook member is configured to provide subchondral support to a distal bone fragment, without causing shortening of the fragment into the metaphyseal bone, and without providing a bending torque directed to the base of the plate. The tooth members of the hook plate are preferably sharpened at their tips and edges to facilitate their impaction. A holder/impactor for gripping the radial hook plate, and for further facilitating impacting of the hook plate without the need to pre-drill pilot holes, is also provided.

摘要： An expansion and compression instrument for fracture fixation. The instrument includes a first handle member, a second handle member, a bearing assembly, and a replaceable tip insert. The bearing assembly axially receives a driver, such as a hexagonal head screwdriver. The replaceable tip insert is adapted to engage an aperture of a fracture fixation plate. The driver is adapted to engage the head of a bone screw, partially threaded into bone proximate the fracture and disposed through a longitudinal slot of the plate. Manual manipulation of the handle members together or apart causes the driver head and replaceable tip insert to become farther apart or closer together, respectively. This in turn, causes the bone screw to be displaced along the longitudinal slot, expanding or compressing the fracture, respectively. Once the fracture has been expanded or compressed to the desired degree, rotation of the screwdriver, facilitated by the bearing assembly, tightens the bone screw, locking the plate into place.

摘要： An intramedullary implant, useful particularly for the fixation of fractures of the radius, the implant comprising a first and second end, both ends configured for entry into the intramedullary canal through an entry point on the bone, such as the fracture site, and configured for positioning within the intramedullary canal of the fractured bone, the first end positioned in the intramedullary space of a first bone fragment and the second end positioned in the intramedullary space of a second bone fragment on the opposite side of the fracture. The first end is positioned by displacing the implant in a first direction and the second end is positioned by displacing the implant in a second direction, substantially opposite to the first direction. The implant further comprises a tip configured to abut an end surface of the second fragment to provide axial support to second fragment.

摘要： A bearing plate for use in bone fixation for fractures, fusion osteotomies and the like, and the plate is provided with one or more spherical holes in which expandable spherical bearings can be rotatably supported. Each of the holes is formed at its periphery in such a way as to provide yielding expansibility of the hole so that upon expansion of the bearing, the hole expands with it to provide elastic resistance to the expanding bearing.
