Thermal analysis of tendon, cartilage and bone samples from shoulder joint replacement patients using differential scanning calorimetry (DSC) and thermogravimetry (DTA/TG)

Abstract Despite advanced imaging techniques, more information on the extent of joint degeneration and modifications in tendon collagen content is required for selecting appropriate type shoulder prosthesis. The goal this study was to compare thermal parameters various tissue samples from patients who had arthroplasty correlate shifts with outcomes radiological histopathological assessments. Rotator cuff (ROC) tendon, hyaline cartilage, subchondral bone were obtained throughout surgery a comminuted 4-part proximal humerus fracture or tear arthropathy. Thermal measured using differential scanning calorimetry thermogravimetry (DTA/TG). ROC: effect damage visible denaturation curves osteoarthritis samples. Only moderately increased enthalpy melting temperature found trauma patients. Cartilage: revealed that structural change generated by pathologic conditions exceeded effects trauma. Bone: degenerative calcification decrease than Correlation: A statistically significant relationship between variables cartilage discovered. Authors suggest analysis may be useful diagnostic process orthopedic posttraumatic diseases.
