“…Researchers have attempted to describe their mechanical properties as a function of their anatomy (Haftek, 1970;Sunderland, 1990). All biological tissues have viscoelastic material properties including peripheral nerves (Abrahams, 1965;Haftek, 1970;Vogl et al, 2015). This is important to note because injuries will depend not only on the magnitude of the deforming force but also on the rate of the force during retraction in hip surgery or hip trauma (Sunderland, 1990).…”

Despite the extensive literature regarding peripheral nerve stretch injuries, there are few studies that compare the nerve histology with the mechanical properties in humans. There is clinical evidence suggesting that the peroneal nerve is at greater risk for injury compared to the tibial nerve following total hip arthroplasty and hip trauma. We examined the two nerves from fresh human cadavers with or without controlled stretch. The mechanical properties, stiffness, and strain were compared with light microscopic preparations in longitudinal sections stained by the trichrome method for collagen and showing the effects of structural deformation. The tibial nerve had an average failure load 1.7× that for the peroneal nerve (P = 0.0001). Although the corresponding average stiffness showed a trend toward being larger (4.39 vs. 3.81 N/mm), the difference was not significant (P = 0.126). Histologically, the perineurium along with the underlying nerve fascicle was undulated in the control specimens and straightened out in the stretched specimens. Peroneal nerves went on to failure at lower loads and exhibited a wavy pattern on pathologic slides after failure, which shows that peroneal nerves fail mechanically before they can unfold. The tibial nerve has a biomechanical and histological advantage compared to the peroneal nerve during tensile testing, which could be the reason why it is less commonly damaged. We conclude that the perineurium is especially protective against deformation changes in human nerves relative to the respective nerve size and number of fascicles.

“…Many investigations have studied the local material properties of costal cartilage (Feng et al, 2001;Guo et al, 2007;Roy et al, 2004;Abrahams and Duggan, 1964;Mattice et al, 2006;Lau et al, 2008). Up till now, there have been no validating data to indicate how these local material properties affect the structural function of costal cartilage.…”

“…The human body, from an engineering point of view, is a load-transmitting mechanism. It is subjected to self-originated and/or environmentally-imposed actions (Abrahams 1965, Paul 1967. These in turn manifest themselves in actions on tissue, and the tissue's capability to withstand and transmit the corresponding loads through deforming appropriately can be characterized in health and disease.…”
