This application is a continuation of U.S. patent application Ser. No. 13/636,416, filed on Nov. 8, 2012, which is a continuation-in-part of International Application No. PCT/US11/42127, filed on Jun. 28, 2011, which claims priority to, and the benefit of, U.S. Provisional Patent Application No. 61/359,028, filed on Jun. 28, 2010. U.S. patent application Ser. No. 13/636,416 also claims priority to and the benefit of U.S. Provisional Patent Application No. 61/537,112, filed on Sep. 21, 2011. The entire contents of each of these prior applications are hereby incorporated by reference herein.
The pair of rod bending devices may each include a plurality of apertures configured and dimensioned to receive therethrough the connecting rod. The plurality of apertures may be defined to receive the rod in different orientations. Bending the connecting rod may include inserting the connecting rod through the apertures of the pair of rod bending devices having different orientations and applying twisting force. In addition, inserting the connecting rod into the connecting rod slots in the bone screws may include positioning the elongate round portion of the connecting rod in the connecting rod slots in the plurality of bone screws. Bending the connecting rod may include bending the connecting rod to conform to a desired contour of the spine.
With reference back to FIGS. 1-4, connecting rod 10 is configured and dimensioned to be selectively and releasably secured to bone screw 50. Connecting rod 10 is defined by an elongate body of a particular length. The elongate body is made of a biocompatible material such as Titanium (Ti—CP) and its alloys (e.g., Ti-6Al-4V), Cobalt-Chrome Alloy (CoCr) or Stainless Steel (SS).
With reference to FIGS. 39 and 40, another embodiment of the present disclosure is shown generally as a spinal stabilization system 1000. Spinal stabilization system 1000 includes at least one bone screw 50 and a connecting rod 500 releasably secured to bone screw 50. Connecting rod 500 is configured and dimensioned to be selectively and releasably secured to bone screw 50. Connecting rod 500 is defined by an elongate body of a particular length. The elongate body is made of a biocompatible material such as Titanium (Ti—CP) and its alloys (e.g., Ti-6Al-4V), Cobalt-Chrome Alloy (CoCr) or Stainless Steel (SS).
a connecting rod formed as a unitary construct, the connecting rod including:
a neck portion defining a pair of concave sides connecting the elongate round section to the elongate head portion, wherein a cross-section of the connecting rod is asymmetric about a first axis of the connecting rod.
2. The spinal stabilization system according to claim 1, wherein the elongate head portion has a non-circular cross-section.
3. The spinal stabilization system according to claim 2, wherein the elongate head portion has a substantially rectangular cross-section.
4. The spinal stabilization system according to claim 1, wherein the neck portion and the elongate head portion extend away from the housing when the elongate round section is disposed in the slot.
5. The spinal stabilization system according to claim 4, wherein the neck portion is rotatable about a longitudinal axis defined by the elongate round section with the elongate round section disposed in the slot of the bone screw.
6. The spinal stabilization system according to claim 1, wherein the cross-section of the connecting rod is symmetric about a second axis transverse to the first axis.
7. The spinal stabilization system according to claim 1, wherein the neck portion is narrower than the elongate round section.
8. The spinal stabilization system according to claim 1, wherein the elongate head portion, the elongate round section, and the neck portion are monolithically formed.
9. The spinal stabilization system according to claim 1, wherein at least one of the elongate round section, the elongate head portion, or the neck portion is formed from a biocompatible material.
10. The spinal stabilization system according to claim 1, wherein at least one of the elongate round section, the elongate head portion, or the neck portion is formed from a material selected from a group consisting of titanium, titanium alloy, cobalt-chrome alloy, and stainless steel.
11. The spinal stabilization system according to claim 1, wherein the housing includes an inner housing and an outer housing selectively positionable relative to the inner housing to lock the connecting rod positioned within the slot defined in the inner housing.
a connecting rod including an elongate round portion defining a longitudinal axis, an elongate head portion, and a neck portion connecting the elongate round portion with the elongate head portion wherein the neck portion is narrower than the elongate round portion, the connecting rod including a cross-section asymmetric about an axis of the connecting rod; and
a bone screw including a housing portion and a screw shaft extending distally from the housing portion, the housing portion defining a slot dimensioned to releasably secure the elongate round portion of the connecting rod therein, wherein the elongate head portion extends away from the housing and is rotatable about the longitudinal axis of the elongate round portion when the elongate round portion is disposed in the slot of the housing portion.
13. The spinal stabilization system according to claim 12, wherein the elongate head portion of the connecting rod has a non-circular cross-section.
14. The spinal stabilization system according to claim 13, wherein the elongate head portion includes a planar surface.
15. The spinal stabilization system according to claim 13, wherein the elongate head portion of the connecting rod has a substantially rectangular cross-section.
16. The spinal stabilization system according to claim 12, wherein the housing portion of the bone screw is transitionable between a locked position and an unlocked position.
17. The spinal stabilization system according to claim 16, wherein the elongate head portion is rotatable when the housing portion is in the unlocked position.
18. The spinal stabilization system according to claim 12, wherein the connecting rod is monolithically formed.
19. The spinal stabilization system of claim 12, further comprising a plurality of bone screws.
20. The spinal stabilization system of claim 12, wherein the housing portion of the bone screw includes an inner housing and an outer housing slidably surrounding at least a portion of the inner housing, the inner housing defining the slot, wherein the outer housing is movable relative to the inner housing between an unlocked state in which the elongate round portion of the connecting rod is releasable from the slot defined in the inner housing and a locked state in which the connecting rod is secured in the slot.
21. A spinal stabilization system comprising:
a connecting rod including a first portion and a second portion, the first portion including an elongate round portion, an elongate head portion including a planar surface, and a neck portion connecting the elongate round portion with the elongate head portion, the second portion including a circular rod coupled to the elongate round portion, the first portion of the connecting rod having a cross-section asymmetric about an axis of the first portion; and
a bone screw including a housing portion and a screw shaft extending distally from the housing portion, the housing portion defining a slot configured to releasably secure the connecting rod therein, wherein the elongate head portion extends away from the inner housing when the elongate round portion is disposed in the slot of the inner housing.
