SECOND HARMONIC GENERATION IMAGING AND NANOINDENTATION OF CARTILAGINOUS TISSUES

Popis výsledku v původním jazyce

Interest on mechanical properties of a cartilaginous endplate (CEP) seems to be more actual at present spine biomechanics. Endplate is a transition zone between intervertebral disc (IVD) and vertebral body which plays undeniable role of a force transmission. Poroelastic structure of CEP assures nutrients delivery into and from the avascular IVD. Knowledge of this amazing a few hundreds micrometres thick indispensable cartilaginous slice could explain basic steps of nature evolution. We are not a first team who tried to study mechanical properties of CEP. Surprisingly, we found alarming anticoincidence in present papers. Mechanical properties of the CEP are presented in literature with large range of values. Elastic moduli are given in the range from 5 MPa to 10 GPa. Which raises the following questions: What causes this large range of values? Is it an erroneously performed experiment? Is it a poorly identified endplate? Is it a non-sensitive macroscopic experiment to inner microstructure of the endplate that causes large range of measured values?
