Abstract: | This study reports several clinical cases for orthopaedic bone regeneration using an injectable bone substitute (MBCP Gel®) to demonstrate its safe use and efficiency in clinical applications. The biomaterial is a composite of microporous bioceramic hydroxyapatite granules that are associated with beta tricalcium phosphate (MBCP) and a synthetic hydrosoluble polysaccharide hydrogel (CE mark 123 and FDA dental domain registered). The present exploratory study demonstrated the generative osseous performance of this injectable bioceramic for filling various orthopaedic bone defects. The clinical cases showed bone ingrowth into the cavities created by drilling when removing the aseptic osteonecrosis of the femoral head during biopsy taking. Furthermore, bone reconstruction was seen after filling large cystic defects, at the time of the revision surgery of the hip prosthesis. Resorption and bone ingrowth with trabecular bone architecture were observed in defects created in long bones (femur and tibia). Patients were followed during 5 months to 1 year. The overall results demonstrated the safe use and the clinical performance of this injectable bioceramic in orthopaedics. |
