This application is continuation of U.S. patent application Ser. No. 12/918,105, filed on Oct. 29, 2012, which is a US national phase of PCT application PCT/FR2009/051658, filed Sep. 2, 2009, published Mar. 18, 2010 as 2010/029246, and claiming the priority of French Patent Application No. 0856035 itself filed Sep. 9, 2008, whose entire disclosures are herewith incorporated by reference.
The zone A1 has a generally cylindrical outer surface 1 a with a limited taper toward its free end. The surface 1 a has a helical rib forming a screwthread 1 a 1.
The zone A2 is flat and has substantially in its center, an opening 1 b adapted to enable elastic deformation of the zone A2. More particularly, the opening 1 b defines at least two anchor arms 1 c and 1 d, each having at least one outwardly projecting tooth 1 c 1, 1 d 1.
To solve the problem of adaptation to the shape of the implantation site, the anchor zones A1 and A2 can be offset at an angle a adapted to the geometry of the bone site. This angle a is comprised between about 1° and 30° and, advantageously, on the order of 10° when the implant is for foot arthrodesis (FIG. 5).
FIGS. 6 and 7 schematically show the positioning of the implant according to the invention between two bone parts O1 and O2. After suitable holes have been made in the bone by a rasp-type tool, the operator screws the thread 1 a into the bone part O1 substantially up to the median zone C that serves as abutment preventing the implant from sinking too deeply into the bone (FIG. 6). The operator then fits the second bone part O2 back onto the anchor arms 1 d and 1 c of the zone A2, the anchor arms then spread and tighten by elasticity (FIG. 7).
The operative technique can be the following: drilling of the two holes with a conventional drill; preparation of the holes with a rasp for the flat side and a bone tap to form the inner screw thread on the cylindrical side; Use of a screwdriver with a gripper end; screwing in the cylindrical side P1 [A1] for an arthrodesis IPP of the foot; and fitting of the bone back onto the flat side [A2] of the implant.
a second end extending from the first end for anchoring to the second bone part,
the second end having a longitudinal axis, a body portion, and a plurality of teeth projecting from the body portion,
wherein the body portion has opposing flat surfaces parallel to the longitudinal axis, and
wherein at least a first tooth of the plurality of teeth is spaced from a second tooth of the plurality of teeth in a direction along the longitudinal axis of the second end, at least the first tooth facing in a direction opposite a third tooth of the plurality of teeth and the second tooth facing in a direction opposite a fourth tooth of the plurality of teeth.
5. The intramedullary implant of claim 1, further comprising a central transition zone between the first and second ends, the central transition zone including a step having a face defining a plane perpendicular to a longitudinal axis of the first end adapted to serve as an abutment preventing overinsertion of the implant into the second bone part.
6. The intramedullary implant of claim 1, wherein the first and second ends are coaxial.
7. The intramedullary implant of claim 1, wherein a longitudinal axis through the first end is offset from the longitudinal axis of the second end by an angle between 1 degree and 30 degrees.
10. The intramedullary implant of claim 1, wherein the first and third tooth are positioned at the same axial location along the longitudinal axis of the second end.
11. An intramedullary implant for use between first and second bone parts, the implant comprising:
a second end extending from the first end for anchoring to the second bone part, the second end having a flat cross-section in a direction perpendicular to a longitudinal axis thereof and a plurality of teeth projecting from the flat cross-section, at least a first tooth of the plurality of teeth spaced from a second tooth of the plurality of teeth in a direction along the longitudinal axis of the second end, and at least the first tooth facing in a direction opposite a third tooth of the plurality of teeth and the second tooth facing in a direction opposite a fourth tooth of the plurality of teeth.
12. The intramedullary implant of claim 11, wherein the first threaded end tapers in a direction away from the second end.
13. The intramedullary implant of claim 11, wherein the second end has an opening defining at least two spreadable arms.
14. The intramedullary implant of claim 11, further comprising a central transition zone between the first and second ends, the central transition zone including a step having a face defining a plane perpendicular to a longitudinal axis of the first end adapted to serve as an abutment preventing overinsertion of the implant into the second bone part.
15. The intramedullary implant of claim 11, wherein the first and second ends are coaxial.
16. The intramedullary implant of claim 11, wherein a longitudinal axis through the first end is offset from the longitudinal axis of the second end by an angle between 1 degree and 30 degrees.
17. A method for performing arthrodesis or osteosynthesis of first and second bone parts, the method comprising the steps of:
inserting a first threaded end of an implant into a first bone part, the implant including a second end extending from the first end, the second end having a longitudinal axis, a body portion, and a plurality of teeth projecting from the body portion,
wherein at least a first tooth of the plurality of teeth is spaced from a second tooth of the plurality of teeth in a direction along the longitudinal axis of the second end, at least the first tooth facing in a direction opposite a third tooth of the plurality of teeth and the second tooth facing in a direction opposite a fourth tooth of the plurality of teeth; and
fitting the second end into the second bone part.
18. The method of claim 17, further comprising the step of preparing the second bone part with a rasp prior to fitting the second end of the implant into the second bone part.
19. The method of claim 17, further comprising the step of tapping the first bone part prior to inserting the first end of the implant into the first bone part.
20. The method of claim 17, wherein the second end has an opening defining at least two spreadable arms, and wherein the arms are in a compressed position while being fitted into the second bone part, the arms expanding once fitted within the second bone part.
