[Long-term results of using Pyrost in orthopedic operations--our own observations].
Based on clinical material of 21 patients age from 9 to 67 years (average 32.8 years) at whom bone defects were supplemented by Pyrost our own observations were presented. Only Pyrost was used in 10 cases, in 9 cases it was used together with homogenous bone grafts and in 2 with autogenous bone grafts. The indications for using Pyrost were following: non union in 9 cases, realloplasty of the hip in 5, after tumour bone resection in 5, inflammation of bone in 1 and supplementation after augenous bone grafting in 1. Analysis of medical documentation and control examinations of 16 patients with follow-up 11.8 years shown good patients' tolerance of Pyrost and absence of locally and generally unuseful reactions. First signs of osteogenesis were observed after 6 weeks. Successive evaluations shown rebuilding of bone to the end of it. Long term results confirmed whole rebuildings of Pyrost to the bone tissue and absence of resorption of Pyrost, without weakness of bone structure. Non-satisfactory results were observed in 3 cases: no consolidations of 2 non unions and 1 septic failed hip realloplasty.
