A biomechanical model for the gravid uterus
نویسندگان
چکیده
The biomechanics of the uterus is studied on a mathematical model based on a shell of ellipsoid of revolution. The myometrium is treated as a homogenous, isotropic and incompressible elastic material using continuum approach and large deformation theory as introduced by Fliigge and Chou [1] and Green and Adkins [2]. The governing equations which are nonlinear differential equations of boundary value type are solved by the shooting method together with the Runge-Kutta integration scheme. The numerical results showing the variation of stretch ratios with uterine pressure are presented graphically for neo-Hookean and Mooney-Rivlin type of materials.

متن کاملGravid Uterus in an Umbilical Hernia
Umbilical hernias large enough to contain a gravid uterus are rare. We report a case of a woman with prolapse of a gravid uterus through a previously repaired umbilical hernia. Our plans for elective surgery with caesarean section and hernia repair were foiled by poor compliance. The hernia was repaired during an emergency caesarean section. We provide details of her management and briefly revi...
متن کاملHerniated gravid uterus through an infra-umbilical laparotomy scar: a case report
Herniation of a gravid uterus through the abdominal wall is a rare and potentially serious condition due to its antecedent complications. Management is determined by gestational age. Simultaneous hernioplasty with cesarean section is considered safe. Clinical awareness of this complication will prevent delay in its diagnosis and treatment. Delay in recognition of this condition can lead to inca...
