### Instruction:

Create a detailed description for the following product: POSEIDON™ ST, belonging to category: Spinal Implant

### Response:
The POSEIDON ST spinal implant offers great flexibility when it comes to adapting to individual circumstances. The slim base body is combinable with end plates in different sizes and angles. If required, the construct can be amplified by an extension at each end of the base body. The end plates have a serration that is firmly anchored in the vertebral bodies. The open-pored titanium grid structure serves to optimise adhesion to the bone.
