Vertebral fusions are part of the surgical treatment of conservative resistant segmental instabilities and degenerative diseases. Many different cage systems were developed over the last decades. The purpose of this study was the examination of the technical possibilities and the clinical results of a cage system without the need of bone substitute ore bone graft. In this study, we used a plasmapore® covered intervertebral block (Prospace®, Aesculap, Tuttlingen).


39 patients (18 women, 21man, average 56 years) with conservative therapy resistant low back pain were operated with the Prospace® cage. The interbody fusion was combined with a posterior transpedicular screw system. 23 patients had chronic discogenic low back pain with modic reaction, 16 patients had degenerative instability up to meyerding grade II associated with spinal stenosis. If decompression was necessary, the cage implantation was performed by dorsal access, otherwise by transforaminal access. Only monosegmental operations were included. The outcome was evaluated with general parameters as well as following specific parameters: German version of North-American-Spine-Society-Instrument (NASS), Oswestry-Low-Back-Pain-Disability Questionnaire, VAS, SF-36.


No serious intraoperative or postoperative complications occurred. Dislocations or implant loosening were not found. The results were excellent or good in 69,2% (27 patients) fair in 23,1% (89 patients) and poor in 7,7% (3 patients).


By regard of a follow up of 2 years, the lumbar intervertebral fusion with plasmapore® covered intervertebral blocks (Prospace®) is an alternative to implants with bone substitute or bone graft. It seems, that Prospace® promotes sufficient osteointegration.
