Abstract EN
This study was designed to analyze the flow and distribution of polymethylmethacrylate (PMMA) in vertebral body through computer simulation.
Cadaveric lumbar vertebrae were scanned through electron beam tomography (EBT).
The data was imported into Mimics software to build computational model.
Vertebral body center and junction of pedicle and vertebral body were chosen as injection points.
Silicone oil with viscosity of 100,000 cSt matching with PMMA bone cement was chosen for injection.
The flow and distribution of silicone oil were analyzed using Fluent software.
In vertebral body, silicone oil formed a circle-like shape centered by injection point on transverse and longitudinal sections, finally forming a sphere-like shape as a whole.
Silicone oil diffused along lateral and posterior walls forming a circle-like shape on transverse section centered by injection point in pedicle, eventually forming a sphere-like shape as a whole.
This study demonstrated that silicone oil flowed and diffused into a circle-like shape centered by injection point and finally formed a sphere-like shape as a whole in both vertebral body and pedicle.
The flow and distribution of silicon oil in computational model could simulate PMMA distribution in vertebral body.
It may provide theoretical evidence to reduce PMMA leakage risk during percutaneous vertebroplasty.
