Abstract
The presentation “Engineering of Abdominal Wall Reinforcement Prostheses” outlines the fundamental principles of the design, development, and evaluation of implants used for abdominal wall reinforcement.
It highlights that the choice of a prosthesis depends on multiple factors: type of hernia, surgical approach, implant positioning, material used, and surgeon preferences. The essential characteristics of implants result from a balance between biology, performance, and biomechanics: porosity to promote tissue integration, elasticity to adapt to the constraints of the abdominal wall, mechanical strength, and the nature of the polymer. The design of the prosthesis is a key element of reinforcement and must incorporate all these characteristics.
The presentation also describes the dynamics of the tissue response and emphasizes that the materials used, particularly polypropylene, must have good biocompatibility and a long clinical history.
Finally, preclinical, clinical, and numerical evaluations — including mechanical testing, physicochemical analyses, animal models, registries, and simulations — help anticipate long-term performance and ensure safety and effectiveness.
