The present disclosure includes a method for reducing a bone fracture and an apparatus such as a cable button for use with a bone plate, the cable button including cable button threads, a plurality of cable button apertures, a hex socket, and a hex opening. The present disclosure also includes a method for reducing a bone fracture and an apparatus such as a cable button for use with a bone plate, the cable button including a plurality of legs, where a leg includes a protrusion, where the protrusion engages the bone plate, and the cable button defines at least one cable button aperture.

A compression force magnifier including a vertical axis through a body and a proximal surface of the body sloped at a predetermined angle relative to the vertical axis. A flat distal surface of the body is disposed opposite the proximal surface. A bore is disposed through the body from the proximal surface through the distal surface. The body is connected to an arm having a connection opening configured to allow connection of the body to a bone plate. The connection opening has a connection axis spaced from the vertical axis.

The present application relates to a pedicle tract stabilization system comprising a bone anchor and a fixation mechanism. The bone anchor is used for stabilizing vertebra during surgical instrumentation of the spine; and the fixation mechanism is used for fixing a bone anchor during the surgical instrumentation. The bone anchor comprises a gripping mechanism for securing the bone anchor to the vertebra cortex and a central body for coupling the gripping mechanism. The fixation mechanism comprises a frame movably attached to the bone anchor. In addition to the bone anchor and the fixation mechanism, the pedicle tract stabilization system may further comprise an external clamping mechanism and a linking mechanism.

A nut for treating a bone includes a head and a body extending longitudinally from the head to a free end and including a channel extending longitudinally thereinto from the free end, the channel configured to engage an end of a bone screw, and an exterior threading extending about the body from an exterior surface thereof along an entire length thereof, an outer contour of the exterior threading defined via radially outermost edges of the exterior threading, a first portion of the outer contour adjacent the head portion having a smaller diameter than a second portion of the outer contour extending from the first portion to the free end of the body.

A construct may include a connector having a first body portion and a second body portion rotatably coupled to another. A first implant cavity may be defined, at least partly, by at least two threaded arm portions defining a first axis between the at least two threaded arm portions. The first implant cavity may include a first receiving cavity configured to adjustably orient a first rod in a plane substantially perpendicular to the first axis, and the second implant cavity may include a second receiving cavity configured to orient a second rod. In some embodiments, the threaded arm portions are configured to receive a first set screw such that when the first set screw is fully tightened along the first axis the first rod is fixed relative to the first body portion in a direction extending substantially parallel with the plane.

The cannulated compression device creates fixation and compression across its tang housing, thus stabilizing and closing a bone fracture during placement. After insertion of the cannulated compression device, tangs are extended outward from the tang housing, locking the tang housing with respect to both rotational and axial movement. A compression nut is then threaded onto the proximal end of the tang housing. The nut has two sets of threads: a first set of threads interfaces with the tang housing, a second set of threads interfaces with the bone. By using different pitches, the amount of linear movement for the first set of threads and second set of threads is different.

A bone repair system, kit and method for percutaneous repair of a bone segment containing a first bone segment and a second bone segment in a patient, each bone segment having a drill hole. The system comprises a longitudinal member configured to contact the first bone segment and the second bone segment and having at least one opening and cleats on the side adapted to contact the first bone segment and the second bone segment; a first fastener assembly configured to be disposed through the opening of the longitudinal member to hold the longitudinal member in place through the opening and the hole in the first bone segment; and a second fastener assembly configured to be disposed through the opening of the longitudinal member to hold the longitudinal member in place through the opening and the hole in the second bone segment.

Embodiments herein are generally directed to fastener or fixation members, such as bone screws, for use in orthopedic stabilization assemblies.

The present invention relates to a surgical screw connection system (100) for use in the region of the pelvic bone. The surgical screw connection system (100) comprises or consists of at least one rod (10) with a first end section (11) and a second end section (13). The rod (10) is cannulated throughout and the first end section (11) consists of or comprises a first threaded section (111). The present invention also relates to an instrument set (200), a treatment set and a method for securing a locking nut (21)

A surgical implant includes a first portion and a second portion. The first portion includes a body and connector assemblies. The body includes a posterior surface and defines a first bore defining an acute angle with respect to a first axis that is orthogonal to the posterior surface. The connector assemblies are disposed on opposing lateral sides of the body. Each connector assembly is selectively rotatable relative to the body. The second portion includes a base extending in a cephalad direction from the first portion, and an extension extending in the cephalad direction from the base. The base defines second bores configured to receive respective bone screws. The extension defines a third bore. The first bore of the body and the third bore of the extension define a second axis. The second bores are defined along a third axis orthogonal to the second axis.
