US Classification:

606 98

Abstract:

An aiming guide aligns a surgical tool with a hole in a bone plate. The aiming guide includes an arm portion having a longitudinal axis, top and bottom surfaces, and first and second ends. The aiming guide further includes a handle portion having upper and lower ends. The handle portion is, at its lower end, connected to the bone plate. The handle portion is, at its upper end, connected to the arm portion. Bores extend from the top surface to the lower surface of the arm portion. Each bore is configured and dimensioned to receive a tool guide in at least two different preset positions which locates the channel in at least two different hole positions. The bore includes two diametrically opposed slots extending along at least a portion of a length of the bore, the slots configured and dimensioned to mate with diametrically opposed knobs extending radially outward from a tool guide. The tool guide has a head and a sleeve portion, which has a centered channel. The sleeve portion and channel are eccentric with respect to the head portion.

International Classification:

A61B017/56

US Classification:

606069000

Abstract:

The present invention is directed to a bone plate and its method of use for reducing a bone fracture, the bone plate having a longitudinal axis, the bone plate comprising an upper surface, a lower surface, a first hole for engaging a head of a first bone anchor. The first hole is configured and adapted to fix a shaft of the first bone anchor along a first axis. A second hole is spaced apart from the first hole along the longitudinal axis. The second hole is for engaging a head of a second bone anchor, and is configured and adapted to fix a shaft of the second bone anchor along a second axis. The first hole and the second hole are configured such that the first axis and the second axis define a single plane and intersect at a point below the lower surface. The shafts of the first and second bone anchors may touch or nearly touch at the point of intersection, such that the first and second bone anchors form a truss.

International Classification:

A61B 17/58

US Classification:

606105000

Abstract:

A tool is disclosed for use in distracting and compressing fractures of any of a variety of bones. In particular, the tool has a pair of engaging arms, one arm having a hook element to engage a bone plate connected to one side of a fracture, and the other arm having at least one recess for engaging a head of a bone screw or guide wire connected to the other side of the fracture. Actuation of the tool causes the opposing bone segments of the fracture to be pushed apart or drawn together, depending on whether the tool handles are squeezed together or pulled apart. The tool may have a scissors joint that allows the ends of the tool to maintain a parallel alignment during operation, thus reducing the chances for misalignment of the bone segments during operation.

The aiming guide further includes a handle portion having upper and lower ends. The handle portion is, at its lower end, connected to the bone plate. The handle portion is, at its upper end, connected to the arm portion. Bores extend from the top surface to the lower surface of the arm portion. Each bore is configured and dimensioned to receive a tool guide in at least two different preset positions which locates the channel in at least two different hole positions. The bore includes two diametrically opposed slots extending along at least a portion of a length of the bore, the slots configured and dimensioned to mate with diametrically opposed knobs extending radially outward from a tool guide. The tool guide has a head and a sleeve portion, which has a centered channel. The sleeve portion and channel are eccentric with respect to the head portion. The tool guide is inserted in a first preset position in order to align a surgical tool with one portion of a two-portion bone plate hole, or in a second preset position rotated 180 from the first preset position, in order to align a surgical tool with the second portion of a two-portion bone plate hole.

International Classification:

A61B 17/80

US Classification:

606290, 606280

Abstract:

A bone plate includes (a) a body having a first surface which, in an operative configuration, faces away from a bone on which the plate is to be mounted and a second surface, which in the operative configuration, faces the bone, the body including a first section extending along a first longitudinal axis and a second section extending along a second longitudinal axis angled with respect to the first longitudinal axis; (b) a first hole extending through the body from the first surface to the second surface and defining a first hole axis, the first hole being structured to lockingly engage a head of a first bone anchor inserted therein such that a shaft of the first bone anchor extends along the first hole axis; and (c) a second hole extending through the body and spaced apart from the first hole. The second hole defines a second hole axis and is structured to lockingly engage a head of a second bone anchor inserted therein such that a shaft of the second bone anchor extends along the second hole axis. The first and second hole axes defines a single plane and intersecting at a point on a side of the bone plate facing the second surface.
