| description | of the efficacy and safety of xenogenic bone graft material impregnated with antibiotics, vancomycin or meropenem, in an experiment on a model of
long bone defect healing in rabbits. Methods The study was performed on 28 male rabbits aged from 8 months to 1.2 years. All animals were modeled
with a cavity defect of the right and left distal femoral metaphysis measuring 4 × 4 × 6 mm. Bone matrix blocks of the same size were implanted into
the defect cavity. Animals of group 1 (n = 8, control) were implanted with a free “clean” bone block. Animals of group 2 (n = 10) with a bone block
saturated with vancomycin. Animals of group 3 (n = 10) with a bone block impregnated with meropenem. To assess the effectiveness and safety of the
material, clinical, radiological, pathomorphological, histological, and laboratory methods were used. Results X-ray signs of substitution of the studied
materials in the defect in animals of group 1 were noted by 182 days, in group 2 – by 84 days, in group 3 – about 182 days. In each group, there was a
complication, arthrosis of the knee joint (one animal in each group). According to the histological study, it was found that in groups 2 and 3, a complete
elimination of xenomaterial in the middle part of the defect and its replacement with trabecular bone was noted by 182 days after implantation. The
severity of irritating action of the materials in the animals of groups 2 and 3 did not exceed the control value. The laboratory blood tests in the animals
of groups 2 and 3 also did not reveal significant differences with group 1. Conclusion The developed osteoplastic materials based on bovine bone
xenomatrix, impregnated with vancomycin or meropenem, have acceptable safety and efficacy characteristics. |
