Mathematical study of a tissue‐implant connection in a ventral hernia repair in a context of the system's parameters

Abstract

Ventral hernia repair is nowadays a well recognized matter in surgery and advanced techniques of operating are developed. However, mechanical properties of the system after an operation are not known so recurrences of the illness happen. The paper describes a simple mathematical model of a human fascia-synthetic implant system. The synthetic mesh is modeled by a cable structure and its elastic supports simulate the human fascia. The junction force in the fascia-implant system is sought. A relation of the force change to variations of some parameters of the system is also studied by applying a sensitivity analysis. The authors conclude that a crucial role for the junction force and a patient's comfort plays the implant's elasticity modulus and initial tension of the mesh is the least important factor.

Biomechanical evaluation of three fixation modalities for preperitoneal inguinal hernia repair: a 24-hour postoperative study in pigs

“… 5 , 16 – 19 In those cases, the test conditions are vastly different from those of physiological ones. Numerical models of the repaired abdominal wall could be of great interest to better understand the complexity of the mechanical response 20 – 23 but, as the assessment of the integration process is still challenging, studies currently focus only on the immediate postoperative time. Biomechanical test methods have been developed to characterize the mechanical behavior of hernia repair under more physiological loading conditions.…”
