Abstract
A transverse fixation device is disclosed. The device includes one or more connecting bodies disposed substantially between two elongate rods. Each connecting body includes a receptacle that is capable of engaging with the two elongate rods. A c-ring comprising an outer surface having a spherical curvature is also included. A third rod may be inserted into the c-ring. A clamp included in the connecting bodies may then be disposed about the c-ring and third rod to allow the connecting bodies to slidingly engage with the third rod.
Claims20
A method for stabilizing spinal elements comprising:
- providing a transverse fixation device, the transverse fixation device comprising:
- a first, second and third elongate rod;
- a connecting body comprising a receptacle facing outwards towards the first rod and away from the second rod, the connecting body further comprising a clamp;
- wherein the clamp is disposed around the third rod,
- wherein the clamp allows the connecting body to slidingly engage with e third rod,
- a screw for connecting the connecting body to the clamp, wherein the screw includes a shaft that is capable of passing through the clamp and into the connecting body;
- and
- wherein the third rod is laterally offset from the receptacle of the connecting body for accommodating anatomical structural elements,
- wherein the clamp, the connecting body and the receptacle are configured as a single monolithic structure
- wherein the receptacle is configured with a uniform curvature to engage between 45% and 75% of a diameter of the first rod, and
- securing the transverse fixation device to the spinal elements.

A method for stabilizing spinal elements comprising:
- providing a transverse fixation device, the transverse fixation— device comprising:
- a first, second, and third elongate rod;
- a c-ring having first and second free ends facing each other to define an opening;
- a connecting body comprising a receptacle facing outwards towards the first rod and away from the second rod, the connecting body further comprising a clamp;
- a screw for connecting the connecting body to the clamp, wherein the screw includes a shaft that is capable of passing through the clamp and into the connecting body,
- wherein the clamp is disposed around the c-ring and the third rod, the clamp having a curved surface corresponding to the outer surface of the c-ring, and
- wherein the third rod is laterally offset from the receptacle of the connecting body for accommodating anatomical structures,
- wherein the clamp, the connecting body and the receptacle is configured as a single monolithic structure,
- wherein the receptacle is configured with a uniform curvature to engage between 45% and 75% of a diameter of the first rod, and
- securing the transverse fixation device to the spinal elements.
7 more elements
A method of stabilizing spinal elements comprising:
- providing a transverse fixation device, the transverse fixation device comprising:
- a first, second and third elongate rod;
- a first and a second one-piece connecting body, the first and second connecting bodies each comprising a receptacle facing outwards towards either the first rod or second rod and away from the other of the first rod or second rod, wherein the first connecting body comprises a first clamp disposed around one end of the third elongate rod and the second connecting body comprises a second clamp disposed around an opposite end of the third elongate rod;
- a first set screw capable of securing the first clamp to the third rod;
- and
- a second set screw capable of securing the second clamp to the third rod, and;
- wherein rotation of the first set screw causes the first clamp to be clamped around the third rod relative to the first connecting body, and
- wherein rotation of the second set screw causes the second clamp to be clamped around the third rod relative to the second connecting body
- wherein the third rod is laterally offset from the receptacles of the first and second connecting bodies for accommodating anatomical structural elements
- wherein the receptacle is configured with a uniform curvature to engage between 45% and 75% of a diameter of the first rod, and
- securing the transverse fixation device to the spinal elements.
