Abstract
A spinal cage for implantation between two adjacent vertebrae includes a polymer composition that includes a polyetherimide. The polyetherimide includes repeating units of the formula
Claims19
A spinal cage for implantation between two adjacent vertebrae, wherein the spinal cage comprises a polymer composition, the polymer composition comprising a polyetherimide, wherein the polyetherimide comprises repeating units of the formula
- wherein R is a divalent radical of the formula
- or combinations thereof wherein Q is selected from —O—, —S—, —C(O)—, —SO2—, —SO—, and —CyH2y— wherein y is an integer from 1 to 5;
- and T is —O— or a group of the formula —O—Z—O— wherein the divalent bonds of the —O— or the —O—Z—O— group are in the 3,3′, 3,4′, 4,3′, or the 4,4′ positions and Z is a divalent group of the formula
- wherein Q2 is selected from —O—, —S—, —C(O)—, —SO2—, —SO—, and —CyH2y— wherein y is an integer from 1 to 5.
1 more element
A spinal fusion system comprising:
- a spinal cage and a plate, wherein the plate secures the spinal cage to the vertebrae, wherein the spinal cage comprises a polymer composition, the polymer composition comprising a polyetherimide, wherein the polyetherimide comprises repeating units of the formula
- wherein R is a divalent radical of the formula
- or combinations thereof wherein Q is selected from —O—, —S—, —C(O)—, —SO2—, —SO—, and —CyH2y— wherein y is an integer from 1 to 5;
- and T is —O— or a group of the formula —O—Z—O— wherein the divalent bonds of the —O— or the —O—Z—O— group are in the 3,3′, 3,4′, 4,3′, or the 4,4′ positions and Z is a divalent group of the formula
- wherein Q2 is selected from —O—, —S—, —C(O)—, —SO2—, —SO—, and —CyH2y— wherein y is an integer from 1 to 5.
2 more elements
A method of treating a spine of a patient comprising:
- removing a damaged spinal disk and inserting a spinal cage into an area of the spine that contained the damaged spinal disk, wherein the spinal cage comprises a polymer composition comprising a polyetherimide,
- wherein the polyetherimide comprises repeating units of the formula
- wherein R is a divalent radical of the formula
- or combinations thereof wherein Q is selected from —O—, —S—, —C(O)—, —SO2—, —SO—, and —CyH2y— wherein y is an integer from 1 to 5;
- and T is —O— or a group of the formula —O—Z—O— wherein the divalent bonds of the —O— or the —O—Z—O— group are in the 3,3′, 3,4′, 4,3′, or the 4,4′ positions and Z is a divalent group of the formula
- wherein Q2 is selected from —O—, —S—, —C(O)—, —SO2—, —SO—, and —CyH2y— wherein y is an integer from 1 to 5.
