Long-term results of treatment of patients with fractures of cervical spine vertebrae with the use of coral-based bone substitute material «BoneMedik-s»

This study represents short- and long-term results of surgical treatment of 39 patients with fractures of cervical spine vertebrae with the use of coral-based bone substitute material, performed between 2010 and 2012. Mean observation time was 3,2 years (2.8-4.0). During the surgery, after decompression of spinal cord, bony defect has been filled with bone substitute material, and then bones have been fixated with metal plate. Computer tomography was used to evaluate osseointegration and biodegradation. In every case we have observed tight donor-recipient bone contact, bone density in contact zone matched the criteria of marked osseointegration ( difference between density in contact zone and appropriate zone of adjacent vertebrae was 3-7%), there were no zones of clarification between bone and substitute material, but even after long-term observation we could not mark full biodegradation of this material.
