Abstract
The invention relates to a resorptive intramedullary implant between two bones or two bone fragments. The implant includes a single-piece body (1) having a generally elongate shape and having, at each end, areas for anchoring to the bone portions in question, characterized in that one of said areas (A1) has a cylindrical cross-section while the other area (A2) has a flat cross-section.
Claims20
A method for fixing first and second bone parts, the method comprising the steps of:
- creating a first hole in a first bone part;
- creating a second hole in a second bone part;
- threading a first end of a monolithic implant into the first hole until a central zone is adjacent the first bone part, the central zone including a first surface extending along a first plane and a second surface extending along a second plane;
- moving first and second anchor arms of a second end of the implant towards one another, the first anchor arm having a third surface extending along a third plane, a fourth surface extending along a fourth plane, a first tooth, and a second tooth, the first and second teeth extending from the first anchor arm in a first direction, and the second anchor arm having a fifth surface extending along a fifth plane, a sixth surface extending along a sixth plane, a third tooth, and a fourth tooth, the third and fourth teeth extending from the second anchor arm in a second direction, the first and second directions being opposite one another;
- and
- fitting the second end into the second hole.
A method for fixing first and second bone parts, the method comprising the steps of:
- drilling a first hole in a first bone part;
- drilling a second hole in a second bone part;
- threading a first end of a monolithic polymeric implant into the first hole until a central zone is adjacent the first bone part, the central zone including a first surface extending along a first plane and a second surface extending along a second plane;
- elastically deforming first and second anchor arms of a second end of the implant towards one another, the first anchor arm having a third surface extending along a third plane, a fourth surface extending along a fourth plane, a first tooth, and a second tooth, the first and second teeth extending from the first anchor arm in a first direction, and the second anchor arm having a fifth surface extending along a fifth plane, a sixth surface extending along a sixth plane, a third tooth, and a fourth tooth, the third and fourth teeth extending from the second anchor arm in a second direction, the first and second directions being opposite one another;
- and
- engaging the first, second, third, and fourth teeth with the second hole.
