Sažetak
The aim of this study was to investigate ectopic bone formation and osseointegration in the posterolateral spinal fusion (PLF) model in New Zealand white rabbits using a novel innovative autologous bone graft substitute (ABGS) containing recombinant human Bone Morphogenetic Protein 6 (rhBMP6), autologous blood coagulum (ABC) and tricalcium-phosphate (TCP) or biphasic (composed of 80% TCP and 20% hydroxyapatite) granulate bioceramics as compression resistant matrix (CRM). Blood samples were collected from rabbit ear marginal vein into tubes without an anticoagulant substance in a volume of 2500 µl. rhBMP6 (125 µg) was mixed with blood and bioceramics. The ABGS implants (n=6 per group) were implanted bilateraly between tranverse processes of the lumbar vertebrae L5-L6 following exposition and decortication of transverse processes. All animals were euthanized on day 50 after surgery. To visualize new ectopic bone formation, lumbar spine was scanned by µCT. The success of spinal fusion was analysed on µCT sections through the anterior and posterior transverse process. Furthermore, lumbar spine was palpated and the mobility of fused transverse processes was tested. Total fusion success rate was 90, 9% and the same result was obtained by both analysis of spinal fusion on µCT sections and by palpatory mobility testing. µCT analyses revealed that an extensive amount of newly formed bone was present in both experimental groups and that there was no significant difference among experimental groups regardless the type of bioceramics used (biphasic bioceramics vs tri-calcium phosphate bioceramics). Bone formation and osseointegration were confirmed on histological sections through newly formed bone between transverse processes. Successful spinal fusion between adjacent transverse processes was confirmed radiologically (µCT sections and µCT analyses), by palpatory segmental mobility test and on histological sections. Therefore, an ABGS containing rhBMP6, ABC and bioceramic granulate might be an innovative and original biological approach for achieving a successful lumbar spine fusion.
