“…Our results do not support the hypothesis that physical exposures lead to formation of medial hernias through a mechanism involving connective tissue degradation and weakening of the transversalis fascia. In accordance with this, a recent study found no differences in key mechanical properties of the transversalis fascia in patients with or without inguinal hernias (unfortunately, the study did not distinguish between medial and lateral hernias) 31. Interestingly (and as noted in the aforementioned recent systematic review,7), two previous studies have observed that lateral hernias were more likely to occur among patients with heavy work 32 33…”

“…The collagen fibres and fibrils are thinner and unevenly distributed in the rectus sheath of patients with a direct or indirect inguinal hernia compared with people without a hernia 26,31 . The collagen fibril diameter of the rectus sheath in patients with a direct inguinal hernia was thinner than in patients with an indirect inguinal hernia 26 , whereas there was no difference in the transversalis fascia fibril diameter between these groups 32,33 . The amount of interfibrillar matrix of fascia transversalis was higher in patients with a direct inguinal hernia than in individuals with an indirect inguinal hernia 32 .…”

“…The mechanical properties of abdominal fascia have been investigated using uniaxial tensile tests, punch tests, and elasticity measurements involving a suction device [9][10][11]. Several of these investigations revealed the elastic properties of fascia and its anisotropic behavior-namely, its direction-dependent response to an applied load [11,12].…”

This investigation is devoted to the study of the viscoelastic behavior of human abdominal fascia from the umbilical region. Seventeen samples 10 mm wide and up to 70 mm long were cut along the primary fiber direction (group FL) or perpendicular to it (group FT) and subjected to relaxation tests. The viscoelastic response of the tissue at three different strain levels (4%, 5%, and 6%) was investigated. The relaxation curves were fitted using a two-stage decaying exponential form. The following parameters were determined: initial stress σ(0), relaxation times τ(1) and τ(2), stress reduction Δσ, initial relaxation modulus E and equilibrium relaxation modulus E(eq), as well as the ratio E/E(eq). Fiber orientation and strain levels were varied to determine their influence on the viscoelastic properties of fascia. The results highlight the inherent viscoelastic mechanical properties of umbilical fascia. The values of the viscoelastic parameters determined for the longitudinal and transverse directions varied markedly. Significant differences were found between the two groups FL and FT for the initial stress at 5% and 6% strain (p < 0.038) and for the initial and equilibrium moduli at the 6% strain level (p < 0.046). The stress reduction in samples from the FL group (45-55%) was less than that in samples from the FT group (37-54%), but this difference was not significant (p > 0.388). The influence of strain level on the parameter values was not statistically significant (p > 0.121). The nonlinear response of the tissue was demonstrated over the chosen strain range.
