摘要: The design of meshes for the treatment incisional hernias could benefit from better knowledge mechanical response abdominal wall and how this is affected by implant. aim study was to characterise behaviour human wall. Abdominal walls were tested ex vivo in three states: intact, after creation a defect simulating an hernia, reparation with mesh implanted intraperitonally. For each state, subjected air pressure loading. Local strain fields determined using digital image correlation techniques. on internal external surfaces exhibited different patterns. patterns surface appeared be related underlying anatomy Higher strains observed along linea alba than perpendicular direction. Under loading, created incision increased compared intact state 5 cases total 6. In addition, repair decreased incised 4 These results suggest that intraperitoneal restores at least partially provides quantification effects various regions.
