In Situ Mechanics of the Subarachnoid Space

Subarachnoid mechanics characterizationCongratulations to PhD Graduate Nik Benko on his publication Mechanical characterization of the human pia-arachnoid complex published in the Journal of Mechanical Behavior and Biomedical Materials. In this study, Nik quantified the normal traction modulus of the pia-arachnoid complex (PaC) in five post-mortem human subjects using hydrostatic fluid pressurization in combination with optical coherence tomography. This study is the first to characterize the mechanics of the human pia-arachnoid complex and quantify material properties in situ. Data from the study suggest implementing a heterogeneous model of the brain-skull interface in computational models of TBI may lead to more realistic injury prediction.
