In this study, a case report is presented with Turner\'s Syndrome with isochromosome carrier, Juvenile Osteoporosis and spontaneous fracture risk. As regards the case, who was referred to Genetic laboratory of Medical Biology Department, Medical Faculty, Dicle University, with pre-diagnosis of growth and development retardation and primary amenore, on average 10 preparats were prepared after performing peripheric blood culture method for chromosomal analysis. The preparats were stained with Giemsa Banding Techniques , and were studied. As a result of chromosomal analysis of the case, whose X-chromatid was positive, the chromosom constitution was determined to be 46,X,i(X)(qter→q10::q10→qter) and diagnosed as Turner\'s Syndrome. In the assessment of the results obtained from lumbar vertebrae L1, L2, L3 and L4 which were subjected to osteo-densitometric analysis, BMD was found to be 0.592g/cm²and it was concluded that it might be Juvenil Osteoporosis with spontaneous fracture risk due to bone mineral density loss of 31% (Z-score: -27) according to WHO criteria. Key words: Juvenile Osteoporosis,Turner\'s Syndrome Chromosomal Analysis
