Abstract
In one embodiment, the present invention includes an intramedullary osteosynthesis or arthrodesis implant including a central body, a first pair of legs extending from the central body to a pair of leg tips, and a second pair of legs extending from the central body, in a direction opposite the first pair of legs, to a pair of leg tips such that the central body, first pair of legs and second pair of legs are positioned alongside a longitudinal axis.
Claims18
An intramedullary osteosynthesis or arthrodesis implant comprising:
- a monolithic body extending along a longitudinal axis, the body including a plurality of notches on an outward-facing surface of the body, at least a first notch of the plurality of notches is spaced from a second notch of the plurality of notches in a first direction along the axis, the first and second notches extending outwardly in the first direction from the axis, and at least the first notch having a taper along the axis in a different direction than a taper of the second notch along the axis, the first notch being wider adjacent to the monolithic body and narrower at an opposite end thereof to define the taper of the first notch, the second notch being wider adjacent to the monolithic body and narrower at an opposite end thereof to define the taper of the second notch,
- wherein the first notch is defined by first and second sidewalls extending from the body, the first sidewall being longer than the second sidewall, the second notch being defined by third and fourth sidewalls, the third sidewall being longer than the fourth sidewall, the second sidewall facing the fourth sidewall such that second sidewall is parallel to the fourth sidewall,
- wherein the monolithic body includes a pair of legs, the first and second notches on a first leg of the pair of legs, the pair of legs being movable about a base point.
An intramedullary osteosynthesis or arthrodesis implant comprising:
- a monolithic body extending along a longitudinal axis, the body including a plurality of notches on an outward-facing surface of the body, at least a first notch of the plurality of notches is spaced from a second notch of the plurality of notches in a direction along the axis, the first and second notches extends outwardly in a first direction from the axis, the first notch being wider adjacent to the monolithic body and narrower at a tip at an opposite end thereof, the second notch being wider adjacent to the monolithic body and narrower at a tip at an opposite end thereof, the first notch being defined by first and second sidewalls extending from the body, the first sidewall being longer than the second sidewall, the second notch being defined by third and fourth sidewalls, the third sidewall being longer than the fourth sidewall, the second sidewall facing the fourth sidewall such that second sidewall is parallel to the fourth sidewall,
- wherein, in an open position, the tip of the first notch extending outwardly a first distance from the axis and the tip of the second notch extending outwardly a second distance from the axis, the first distance is greater than the second distance,
- wherein the first and second notches are movable about a base point from the open position to a closed position.
An intramedullary osteosynthesis or arthrodesis implant comprising:
- a monolithic body extending along a longitudinal axis, the body including a plurality of notches on an outward-facing surface of the body, at least a first notch of the plurality of notches is spaced from a second notch of the plurality of notches in a direction along the axis, the first and second notches extending outwardly in the same direction from the axis, the first notch having a first taper toward a tip of the first notch and the second notch having a second taper toward a tip of the second notch, the first taper being longer than the second taper, the first notch being wider adjacent to the monolithic body and narrower at an opposite end thereof to define the first taper, the second notch being wider adjacent to the monolithic body and narrower at an opposite end thereof to define the second taper,
- wherein the first notch is defined by first and second sidewalls extending from the body, the first sidewall being longer than the second sidewall, the second notch being defined by third and fourth sidewalls, the third sidewall being longer than the fourth sidewall, the second sidewall facing the fourth sidewall such that second sidewall is parallel to the fourth sidewall,
- wherein the monolithic body includes a pair of legs, the first and second notches on a first leg of the pair of legs, the pair of legs being movable about a base point.
