“…The custom-made clamps used in our study were previously used in a biomechanical study of muscles in other species. 25 No slippage was reported in the Chism et al 25 study with the use of dumbbell-shaped specimens, as recommended for tensile testing of elastomers 10 and cheese grater clamps. No slippage at tissue-grip interface was observed in our study.…”

ObjectiveTo compare biomechanical properties and mechanism of failure of 3 regions of ventral abdominal wall in cats by using 2 suture materials, 2 suture bite‐to‐stitch intervals (SBSI), and full‐thickness versus fascia‐only closure.Study DesignRandomized, cadaveric, ex vivo mechanical testing.Sample Population16 adult cat cadavers, 3 samples per cat.MethodsThree regions of ventral abdominal wall were mechanically tested (N = 48 samples). Preumbilical, umbilical (U), and postumbilical (POU) regions were harvested by using a template. The thickness of the linea alba was recorded. Six samples without celiotomy served as controls. Twenty‐eight samples were randomized to SBSI (2 × 2 or 5 × 5 mm) and suture material (3‐0 polyglactin 910 or 3‐0 polydioxanone) for simple continuous celiotomy closure. Fourteen samples were randomized to full‐thickness or fascia‐only closure. Samples were tested by linear distraction; tensile strength and mechanism of failure were recorded. Effects of body weight, thickness of linea alba, anatomic region, SBSI, type of closure, and suture material were evaluated by mixed model linear analysis. Load to failure was compared between males and females, full‐thickness and fascia‐only closure by independent t test, with P < .05 considered statistically significant.ResultsThe POU region achieved lower loads to failure. Load to failure was greater in males compared with females. No difference was detected between full‐thickness and fascia‐only closure. Failure most commonly occurred by tearing of suture through tissues. Tissue failure with suture line loosening occurred mainly in the 5 × 5‐mm SBSI group.ConclusionThe POU region is biomechanically weak and may therefore be predisposed to incisional herniation.

“…The reported results show that the MF direction is the weakest direction in this muscle in terms of mechanical resistance to elongation. A more surprising behavior has been reported for the chicken pectoralis muscle in which the tissue is stiffer in the direction of 45° with respect to the MF direction (Mohammadkhah et al 2016).…”

“…Most of the passive muscle models in the literature do not consider any distinction between CFs and MFs, or at least do not consider the mechanical effects of CFs on the 3-D behavior of tissue. These models cannot provide a realistic account of the observed stress-stretch responses in muscle tissue, especially in tissue that amazingly shows stronger resistance against elongation in a direction different from the MF alignment , Hernández et al 2011, Mohammadkhah et al 2016and Wheatley et al 2016. Recently, Grasa et al (2016) have introduced the CFs in their passive muscle model that can describe such an amazing stress-stretch behavior, but this model does not include the 3-D distribution of the CFs.…”

“…Depending on the sarcomere length, the mean CF angle with respect to the MF axis varies in the range of 20° to 80°. This explains why mechanical passive properties of some muscles are stronger in the direction transverse to the MF direction , Mohammadkhah et al 2016and Wheatley et al 2016. For these muscles, the available CLs, in which the CFs and the MFs are identified with the same direction, cannot describe the observed stress-stretch behavior.…”

“…Furthermore, a new CL is proposed for the passive behavior of muscle tissue which can specifically take into consideration the 3-D effects of the CFs. To evaluate the proposed model, its accuracy in approximating the experimental data is demonstrated for our data about the bovine genioglossus tissue as well as for published experimental data about the pig longissimus dorsi muscle and the chicken pectoralis muscle (Mohammadkhah et al 2016).…”

Mechanical properties of muscle tissue are crucial in biomechanical modeling of the human body. Muscle tissue is a combination of Muscle Fibers (MFs) and connective tissue including collagen and elastin fibers. There are a lot of passive muscle models in the literature but most of them do not consider any distinction between Collagen Fibers (CFs) and MFs, or at least do not consider the mechanical effects of the CFs on the Three-Dimensional (3-D) behavior of tissue. As a consequence, unfortunately, they cannot describe the observed stress-stretch behavior in tissue in which the reinforced direction is not parallel to the MF direction. In this research, a new passive muscle model is presented, in which the CFs are separately considered in the formulation: they are distributed along the MFs in a cross-shaped arrangement. Thanks to this new architecture, a mechanical reinforced direction can be proposed, in addition to the muscle main fiber direction. The passive biomechanical properties of the genioglossus muscle of a bovine tongue have been measured under uniaxial tensile tests. To characterize the 3-D response of the tissue, tests have been performed in different directions with respect to the MF direction. Moreover, a Constitutive Law (CL) has been proposed for modeling this behavior. In addition to our measurements on the bovine genioglossus muscle, results published in the literature on experimental data from the longissimus dorsi of pigs and the chicken pectoralis muscle were used to appraise the applicability of the proposed model. It is demonstrated that the proposed passive muscle model provides an accurate description of the fiber-oriented nature of muscle tissue. Also, it has been shown that using Finite Element Analysis (FEA) it might be possible to predict the angle θ between CFs and MF.

The passive properties of skeletal muscle are often overlooked in muscle studies, yet they play a key role in tissue function in vivo. Studies analyzing and modeling muscle passive properties, while not uncommon, have never investigated the role of fluid content within the tissue. Additionally, intramuscular pressure (IMP) has been shown to correlate with muscle force in vivo and could be used to predict muscle force in the clinic. In this study, a novel model of skeletal muscle was developed and validated to predict both muscle stress and IMP under passive conditions for the New Zealand White Rabbit tibialis anterior. This model is the first to include fluid content within the tissue and uses whole muscle geometry. A nonlinear optimization scheme was highly effective at fitting model stress output to experimental stress data (normalized mean square error or NMSE fit value of 0.993) and validation showed very good agreement to experimental data (NMSE fit values of 0.955 and 0.860 for IMP and stress, respectively). While future work to include muscle activation would broaden the physiological application of this model, the passive implementation could be used to guide surgeries where passive muscle is stretched.
