Investigation of bone tissue mechanical properties in the supra-acetabular region

Introduction The investigation of the trabecular bone strength in acetabular area and its dependence on age gender may provide a theoretical basis for development implants replacement. purpose this study was to determine mechanical characteristics tissue supra-acetabular region patients different groups. Materials methods cadaveric material 60 studied included 20 young (age range, 18 44), middle-aged range 45 59) elderly 74). Fragments 3 × 1.5 cm size were removed from using an osteotome. Cylindrical specimens, 6 mm diameter 9 high, produced these fragments crown cutter. All samples subjected uniaxial compression at loading rate 1 mm/ min. Results Comparison male each parameters did not reveal differences (p > 0.05). In women groups, magnitude elastic deformation significantly both by multiple analysis pairwise comparison groups < There also no statistically significant difference maximum stress modulus elasticity Discussion data obtained behavior values are explained spatial arrangement fibers structural proteins, cross-linking profile collagen, degree matrix mineralization, structure hydroxyapatite, amount bound water. Conclusion patients, do change with age. women, value increases tensile ages show any changes.
