Definitions
- a copolymer is a material created by polymerizing a mixture of at least two monomers. Suitable combinations can for example exist of two monomers, three monomers (a so-called terpolymer), four monomers, etcetera.
- a monomer comprising covalently bound iodine is used.
- 4IEMA is used since this crystalline material can be easily prepared in bulk-quantities in pure form via radical polymerization.
- 2-[2', 3', 5'-triiodobenzoyl]-oxo-ethyl methacrylate is used, which is useful to introduce a high level of X-ray contrast in the copolymer, since during polymerization three iodine atoms are introduced per monomer.
- the hydrogel In order to give the hydrogel the right mechanical properties the hydrogel generally has a maximal EWC of 95 wt.% .
- the suitable monomers in the copolymer of the present invention can have one or more reactive groups.
- at least one monomer is used having two or more reactive groups.
- a polymer network can be formed.
- monomers having two reactive groups, suitable for the present invention are dimethacrylates, divinylbenzene, or allylmethacrylate.
- Figure 4 shows the resulting X-ray image of the implantation whereby samples of Examples 3 (H95) and 4 (H90) were implanted between two adjacent vertebrae of a porcine cadaver. Three intervertebral structures are seen: the native disc ( * ) on the bottom, the sample of Example 4 in the middle and the sample of Example 3 on top. The native discus is seen as a non-absorbing (white) band, while samples of Experiments 3 and 4 are clearly visible as X-ray absorbing bands.
