Osteogenesis imperfecta as an interdisciplinary medical problem]

In years 2001-2003 six children (3 boys ond 3 girls) from 2.1 to 18.7 years old with osteogenesis imperfecta (OI) were treated in our clinic. Besides clinical and radiological evaluation, densitometry and biochemical analysis of collagen were performed. Biochemical analysis was performed on cultured in vitro fibroblasts from the skin biopsies. Based on this findings 1 child was graded as type I of OI, 4 children as type III and 1 as type IV. Recognition of collagen defect helps with diagnosis and makes the decision for pharmacological treatment easier. In 1 child with the dramatic type III OI therapy with pamidronian was implemented with good result. Performed surgical treatment, intramedullar stabilisation with Rush rod, proved to be useful choice in correcting axial deformations of the lower extremities and preventing from the future fractures.
