Summary
Simulated perfusion using SimLife® technology improved the identification and dissection of the corona mortis (CMOR) in cadaveric pelvic models. This enhanced anatomical visualization aids surgeons in managing life-threatening open book pelvic fractures.
Area of Science:
- Anatomy
- Surgical Education
- Medical Technology
Background:
- Open book pelvic ring fractures pose significant risks, including life-threatening hemorrhage.
- Identifying the corona mortis (CMOR) during surgical fixation is crucial to prevent iatrogenic vascular damage.
- Traditional anatomical training may not fully replicate the dynamic challenges of surgical procedures.
Purpose of the Study:
- To compare cadaveric dissection models for identifying the corona mortis (CMOR).
- To assess the utility of SimLife® perfused cadaver technology in visualizing dynamic anatomy.
- To evaluate the effectiveness of SimLife® in understanding CMOR topography for surgical training.
Main Methods:
- Twelve human cadaveric pelvises were dissected using two protocols.
- Model A involved dissection without perfusion.
- Model B utilized SimLife® pulsatile perfusion for dissection.
Main Results:
- The corona mortis (CMOR) was identified in 66.67% of cases.
- Morphometric parameters (length, diameter, distance to pubic symphysis) were significantly greater in the SimLife® perfused model (Model B).
- Statistical significance was observed for length (p=0.029), diameter (p=0.01), and distance (p=0.022).
Conclusions:
- SimLife® perfusion facilitates easier identification and dissection of the CMOR.
- This perfused cadaver model enhances understanding of CMOR topography.
- The technology offers valuable surgical training for managing open book pelvic lesions.

01:07Laminar and Turbulent Flow
Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the streamlines...
01:28Magnetostatic Boundary Conditions
An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...
01:17Accelerating Fluids
When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

01:13Mortar Joint Deterioration in Masonry
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

01:11Pressure Variation in a Fluid at Rest
In a fluid at rest, the pressure at any point beneath the fluid surface depends solely on the depth, not on the container's shape or size. This principle, known as hydrostatic pressure, arises because, in stationary fluids, there is no acceleration, meaning the forces within the fluid balance out. Only vertical forces, caused by the weight of the fluid above, contribute to pressure changes with depth.

01:17Steady, Laminar Flow Between Parallel Plates
Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.
