[BAS-0 Bioactive Glass-ceramic as a Bony Tissue Replacement (Clinical Experience after a Longterm Interval after...

The authors present evaluation of the application of BAS-0 bioactive glass-ceramics at the Orthopaedic Clinic in Hradec Králové in the period 1990-1997. Bioactive glass-ceramics was implanted in total in 106 patients of which in 38 patients during THR revision surgery and in 20 patients with bone infection. Of 48 patients with bioactive glass-ceramics used as a bony tissue replacement in filling the defects during operations of benign tumours or tumours of similar affections and in the surgical treatment of fractures of tibial plateau, 31 were followed up for the period ranging between 3 months to 6 years (average 3,2 years). In all patients followed the soft tissue surrounding the implanted glass-ceramics shows no reaction, radiographs showed bone trabeculae continuously pass over to the surface of the glass-ceramic particles and in no case we recorded periostal reaction or any other X-ray changes showing irritation, loosening or extrusion of this bone replacement. Key words: bioactive glass-ceramics, benign bone tumours and tumour-like affections, fractures of tibial plateau.
