Abstract

Abstract An element for fixing a ligament adapted to be inserted in an osseous canal comprising an at least partially hollowed truncated element including an internal conduit adapted to receive one of the end sections of a ligament. A fastening member is provided that extends through the truncated element and clamps the respective end section of the ligament inside the conduit.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 249 words
An element for fixing a deformable ligament within an osseous canal comprising: a truncated conical element including a first diametric end portion and a second, widened diametric end portion, said truncated conical element being adapted to be received within an osseous canal with at least part of said second, widened diametric portion projecting outside the osseous canal, said truncated conical element being formed with an internal conduit defining a longitudinal axis and which is adapted to receive a deformable end of a ligament, said internal conduit including a widened zone defined by a recessed segment, said truncated conical element also being formed with a threaded bore opening at the part of said second widened diametric end portion projecting outside the osseous canal and opening into said internal conduit, said bore being inclined with respect to said longitudinal axis and opening into sad internal conduit at a position opposite the recessed segment of said internal conduit; and a threaded fastener positioned within said bore, said fastener having a first end that is accessible form outside said bore and a second end that is adapted to be shifted toward said recessed segment whereby, upon insertion of a deformable end of a ligament within said internal conduit, said fastener can be threaded within said bore such that the second end of said fastener engages the ligament to cause the ligament to deform so as to fill said recessed segment by taking a bend shape thereby retaining the ligament within said internal conduit.
Claim 2
Dependent Claim 249 words
An element for fixing a deformable ligament within an osseous canal comprising: a truncated conical element including a first diametric end portion and a second, widened diametric end portion, said truncated conical element being adapted to be received within an osseous canal with at least part of said second, widened diametric portion projecting outside the osseous canal, said truncated conical element being formed with an internal conduit defining a longitudinal axis and which is adapted to receive a deformable end of a ligament, said internal conduit including a widened zone defined by a recessed segment, said truncated conical element also being formed with a threaded bore opening at the part of said second widened diametric end portion projecting outside the osseous canal and opening into said internal conduit, said bore being inclined with respect to said longitudinal axis and opening into sad internal conduit at a position opposite the recessed segment of said internal conduit; and a threaded fastener positioned within said bore, said fastener having a first end that is accessible form outside said bore and a second end that is adapted to be shifted toward said recessed segment whereby, upon insertion of a deformable end of a ligament within said internal conduit, said fastener can be threaded within said bore such that the second end of said fastener engages the ligament to cause the ligament to deform so as to fill said recessed segment by taking a bend shape thereby retaining the ligament within said internal conduit.
Claim 3
Dependent Claim 20 words
An element according to claim 1, wherein the first diametric end portion of said truncated conical element is rounded edges.
Claim 4
Dependent Claim 20 words
An element according to claim 1, wherein said recessed segment is defined by a bent section of said internal conduit.
Claim 5
Dependent Claim 28 words
An element according to claim 1, wherein the first diametric end portion of said truncated conical element has an associated diameter less than or equal to 5 mm.
Claim 6
Dependent Claim 29 words
An element according to claim 4, wherein the second, widened diametric end portion of said truncated conical element has an associated diameter less than or equal to 8 mm.
Claim 7
Dependent Claim 33 words
An element according to claim 1, wherein the first end of said threaded fastener defines a head having a screwing groove formed therein and the second end of said threaded fastener is tapered.
