6974460, Dec 13, 2005

Filed:

Mar 5, 2002

Appl. No.:

10/091068

Inventors:

John Carbone - Lutherville MD, US
Aaron Markworth - Pompton Lakes NJ, US
Michael Horan - Charleston SC, US
Yves Crozet - Ramsey NJ, US

Assignee:

Stryker Spine

International Classification:

A61B017/70

US Classification:

606 61, 606 60

Abstract:

A bone fixation assembly including a coupling element having an inner surface defining a first bore coaxial with a first longitudinal axis, and a second bore coaxial with a second longitudinal axis, whereby the second longitudinal axis intersects the first longitudinal axis. The coupling element has a seat adjacent the lower end of the coupling element, the seat being defined by the inner surface of the coupling element. The assembly includes an anchoring element assembled with the coupling element, the anchoring element having a first end for insertion into bone and a head spaced from the first end, the head being in contact with the seat of the coupling element. The assembly provides sufficient angulation between adjacent anchoring elements securing a common orthopedic rod, and is particularly useful for assemblies mounted in spines having abnormal curvatures and in the cervicothoracic region of the spine.

International Classification:

A61B 17/88

US Classification:

606279

Abstract:

In one embodiment, the present invention includes a method of stabilizing a spine including providing a coupling element having an uppermost end defining a first plane, a lowermost end defining a second plane, and at least one bore extending from said uppermost end toward said lowermost end, wherein said first and second planes intersect one another, assembling said coupling element with an anchoring element, and after the assembling step, securing said anchoring element in bone.

International Classification:

A61B 17/70
A61B 17/88

Abstract:

In one embodiment, the present invention includes a bone fixation assembly comprising a coupling element and a bone anchor. The coupling element has an upper surface with a first diameter defining a first bore extending along a first axis, a lower surface with a second diameter defining a second bore extending along a second axis, and an internal surface area defining a seating portion adjacent to the lower surface. The bone anchor has an insertion end opposite of a head. The head may be curved for receipt within the seating portion. The first diameter of the first bore is greater than the second diameter of the second bore. Likewise, the first and second axes may intersect such that the first and second bores are in communication with one another. Related elements and systems of this assembly are also disclosed.

International Classification:

A61B 17/70

Abstract:

In one embodiment, a method of stabilizing bone, including providing a fixation assembly including an anchoring element and a coupling element, the coupling element having an upper surface with a first diameter defining a first bore extending along a first axis, a lower surface with a second diameter smaller than the first diameter defining a second bore extending along a second axis, the first and second axes intersect such that the first and second bores are in communication with one another and an internal surface area defining a seating portion adjacent to the lower surface, and the anchoring element having a head portion positioned within a coupling element; securing the fixation assembly to bone.

In one embodiment, the present invention includes a bone fixation assembly comprising a coupling element and a bone anchor. The coupling element has an upper surface with a first diameter defining a first bore extending along a first axis, a lower surface with a second diameter defining a second bore extending along a second axis, and an internal surface area defining a seating portion adjacent to the lower surface. The bone anchor has an insertion end opposite of a head. The head may be curved for receipt within the seating portion. The second diameter of the second bore may be greater than the first diameter of the first bore or vice versa. Likewise, the first and second axes may intersect such that the first and second bores are in communication with one another. Related elements and systems of this assembly are also disclosed.
