Spinologics wins the ANSYS Hall of Fame competition for its FE simulation capabilities

Posted on 01/8/15

ANSYS Inc., the makers of the leading simulation platform used at Spinologics, has awarded Spinologics with an induction into their Hall of Fame for the advanced use of its computational platform.  The expertise at Spinologics allows for the customized coding of state of the art simulations tailored towards investigation spine pathological studies and the evaluation of medical devices.  Many years of development and validation has positioned Spinologics as a world leaders in the biomechanical analysis and understanding of the spine.  Read more…

Spinal Surgery Simulation: Improvements and new features.

Posted on 08/18/14

Spinologics presents the new features of its spinal surgery FE simulator. The latest release includes notably an improved multi-axial screw finite element model and a new spinal hook model. Additional surgical maneuvers can be simulated: in-situ bending, vertebral derotation and contraction-distraction. Gravitational effects are now included in the simulation process. Revision surgeries, with up to 4 rods, can now be analyzed. The surgery simulator of Spinologics can help you testing/optimizing your spinal instrumentation design during or after product development, comparing your spinal instrumentation to a generic design, proving your new spinal instrumentation design is an improvement over previous versions or other existing designs or assist you in obtaining regulatory approval

3-points bending test of spinal rods: FE Simulation

Posted on 08/14/14

Spinologics presents his finite element model allowing to simulate the 3-points bending test of spinal rods. The model allows evaluating in-silico the stiffness and yield strength of any spinal rod design. Any material (Ti, CoCr, SS, etc..) can be modeled. Plasticity is included.

The FE model can help exploring and optimizing spinal rod designs, validating experimental tests or obtaining FDA approval. Read more…

Development of a Detailed Volumetric Finite Element Model of the Spine to Simulate Surgical Correction of Spinal Deformities

Posted on 10/15/13

Spinologics publishes another study demonstrating the efficacy of its parametric volumetric detailed finite element model of the osteoligamentous spine to simulate surgical corrections of common spinal pathologies.  This model serves as a time and cost effective manner to evaluate medical devices from concept to market.

Biomechanical Assessment of Reduction Forces Measured During Scoliotic Instrumentation Using Two Different Screw Designs

Posted on 10/15/13

Spinologics teams up with DePuy Synthes Spine to compare two pedicle screw designs to evaluate their biomechanical differences.  Results suggest that a screw design enabling a larger degree of motion and excursion range to capture the spinal rod, such as the Favored Angle screw for example, effectively reduce pullout forces measured at the screw-vertebra interface.
