Abstract
A scapholunate stabilisation implant includes a central part having an elastic deformation capacity enabling the traction movements of the implant, and two end parts having an elastic deformation capacity enabling the torsional movements of the implant, the end parts being provided with at least one hole through which the fixing screw is passed, the central part and the end parts being connected by rods that can withstand the torsional deformations of the implant.
Claims19
A scapholunate stabilization implant, including a central part, a first end part and a second end part, the first and second end parts being provided each with at least one through-hole for the passage of fastening screws, in which the central part and said first and second end parts are connected respectively by a first and a second torsion bar and in which the central part of the implant includes a first and a second central bar and lateral bars each of the lateral bars being connected, by a plurality of cross beams, respectively to the first and the second central bar and wherein the central part presents, in its middle, a transversal spacing separating the first and second central bars and delimited by the lateral bars.
A scapholunate stabilization implant, including a central part, a first end part and a second end part, the first and second end parts being provided each with at least one through-hole for the passage of fastening screws, in which the central part and said first and second end parts are connected respectively by a first and a second torsion bar and in which the central part of the implant includes a first and a second central bar and lateral bars each of the lateral bars being connected, by a plurality of cross beams, respectively to the first and the second central bar, and wherein the end parts have the shape of an asymmetric arrow having fins, and wherein the fins feature the through-holes for fastening screws, and their central rods which enable said ends to be connected to the central part of the implant constitute the torsion bars of said implant.
A scapholunate stabilization implant, including a central part, a first end part and a second end part, the first and second end parts being provided each with at least one through-hole for the passage of fastening screws, in which the central part and said first and second end parts are connected respectively by a first and a second torsion bar and in which the central part of the implant includes a first and a second central bar and lateral bars each of the lateral bars being connected, by a plurality of cross beams, respectively to the first and the second central bar, wherein the central part of the implant is made of a titanium alloy, and the end parts of said implant are made of a polymer, the torsion bars connecting the central part to the end parts being thus executed in a titanium alloy encapsulated in polymer.
