Aim: To investigate the prevalence of osteoporosis in thoracic surgery patients and highlight the clinical significance for physicians. Methods: Thoracic computed tomographies(CT) of 306 patients were examined for medullary density of T12 vertebra. Hounsfield units (HU) between men and women; under the age of 70 and those who are "70 years and older" groups were compared. To evaluate the diagnostic performance of the age parameter in predicting osteoporosis, ROC analysis, and logistic regression analysis were used. The rib cortical defects identified in this study group and their causes were explained. Results: HUs of 51 subjects (or 16.7%) was less than 110 (osteoporosis); of 177 people (57.8%) was higher than 160 (normal). HU values ranged from 111 to 159 (borderline) for 78 individuals (25.5%). There was no significant difference between males and females. It was discovered that the difference between the population under 70 and the population over 70 was statistically significant (p

Objective: The study aimed to assess the sternum's morphology and morphometry, and to find anomalies and diseases using breast magnetic resonance imaging (MRI). Materials and Methods: Retrospective evaluations of 320 breast MRIs were conducted. Congenital abnormalities accompanying pathological conditions were investigated. The sternum overall’s length, the manubrium-corpus’ width and length, and the manubrium-corpus-xiphoid’s shape were all measured. The relationship between the manubriosternal fusion and age was analyzed. Results: Pectus excavatum, sternal band, sternal foramen, angled sternum and the sternal band, rachitic rosary, intraosseous ganglion, sternoclavicular joint degeneration, sternoclavicular joint ganglion cyst and costal cartilage calcifications, breast carcinoma metastasis, enchondroma and invasion of costal cartilages by malignant mesenchymal tumour were determined. The average length of the sternum was 144±14 mm, the manubrium length is 46±6 mm and the corpus length is 89±10 mm for adults. Manubrium was most commonly trapezoid in shape, the corpus was longitudinal oval and xiphoid was flat. 67% had no manubriosternal fusion. The degree of manubriosternal fusion did not show statistically significant correlation with increasing age. Conclusion: The sternum, sternoclavicular, and sternocostal joints are susceptible to a wide range of congenital abnormalities and clinical conditions. Age increase has no relation to manubriosternal fusion.
