Abstract: A composite structure comprising a first porous portion comprising a plurality of interconnected pores and a second solid portion having a first surface, said first surface secured to said first portion wherein said first and second portions are fabricated from a polymer material. The material may be suitable for implant, illustratively vertebral or spinal implants, comprising a rigid biocompatible polymer such as PEEK comprising a plurality of interconnected pores. The polymer illustratively has a porosity of between 50% and 85% by volume and in a particular embodiment is able to withstand pressures of up to 20 MPa. The porous PEEK material may also have a minimum thickness in any dimension of one (1) inch.
